1.6 Safety

1.6.1 Summary of safety markings

These User Instructions contain specific safety markings where non-observance of an instruction would cause hazards. The specific safety markings are:

This symbol indicates electrical safety instructions where non-compliance will involve a high risk to personal safety or the loss of life.

This symbol indicates safety instructions where non-compliance would affect personal safety and could result in loss of life.

This symbol indicates “hazardous and toxic fluid” safety instructions where non-compliance would affect personal safety and could result in loss of life.

This symbol indicates safety instructions where non-compliance will involve some risk to safe operation and personal safety and would damage the equipment or property.

This symbol indicates explosive atmosphere zone marking according to ATEX. It is used in safety instructions where non-compliance in the hazardous area would cause the risk of an explosion.

Always coordinate repair activity with operations and health and safety personnel, and follow all plant safety requirements and applicable safety and health laws and regulations.

1.6.3 Safety action

This is a summary of conditions and actions to help prevent injury to personnel and damage to the environment and to equipment. For p roducts used in potentially explosive atmospheres section 1.6.4 also applies.

PREVENT EXCESSIVE EXTERNAL PIPE LOAD Do not use pump as a support for piping. Do not mount expansion joints, unless allowed by Flowserve in writing, so that their force, due to internal pressur e, acts on the pump flange.

ENSURE CORRECT LUBRICATION (See section 5, Commissioning, startup, operation and shutdown.)

START THE PUMP WITH OUTLET V ALVE PAR TLY OPENED (Unless otherwise instructed at a specific point in the User Instructions.) This is recommended to minimize the risk of overloading and damaging the pump motor at full or zero flow. Pumps may be started with the valve further open only on installations where this situation cannot occur. The pump outlet control valve may need to be adjusted to comply with the duty following the run-up process. (See section 5, Commissioning start-up, operation and shutdown.)

This symbol is used in safety instructions to remind not to rub non-metallic surfaces with a dry cloth; ensure cloth is damp. It is used where noncompliance in the hazardous area would cause the risk of an explosion.

This sign is not a safety symbol but indicates

an important instruction in the assembly process.

1.6.2 Personnel qualification and training

All personnel involved in the operation, installation, inspection and maintenance of the unit must be qualified to carry out the work involved. If the personnel in question do not already possess the necessary knowledge and skill, appropriate training and instruction must be provided. If required the operator may commission the manufacturer/supplier to provide applicable training.

Page 5 of 64

NEVER RUN THE PUMP DRY

INLET VALVES TO BE FULLY OPEN WHEN PUMP IS RUNNING Running the pump at zero flow or below the recommended minimum flow continuously will cause damage to the seal.

DO NOT RUN THE PUMP AT ABNORMALLY HIGH OR LOW FLOW RATES Operating at a flow rate higher than normal or at a flow rate with no backpressure on the pump may overload the motor and cause cavitation. Low flow rates may cause a reduction in pump/bearing life, overheating of the pump, instability and cavitation/vibration.

NEVER DO MAINTENANCE WORK

WHEN THE UNIT IS CONNECTED TO POWER

HAZARDOUS LIQUIDS

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

When the pump is handling hazardous liquids care must be taken to avoid exposure to the liquid by appropriate siting of the pump, limiting personnel access and by operator training. If the liquid is flammable and/or explosive, strict safety procedures must be applied.

Gland packing must not be used when pumping hazardous liquids.

DRAIN THE PUMP AND ISOLATE PIPEWORK BEFORE DISMANTLING THE PUMP The appropriate safety precautions should be taken where the pumped liquids are haza rdous.

FLUORO-ELASTOMERS (When fitted.) When a pump has experienced temperatures over 250 ºC (482 ºF), partial decomposition of fluoroelastomers (example: Viton) will occur. In this condition these are extremely dangerous and skin contact must be avoided.

HANDLING COMPONENTS Many precision parts have sharp corners and the wearing of appropriate safety gloves and equipment is required when handling these components. To lift heavy pieces above 25 kg (55 lb) use a crane appropriate for the mass and in accordance with current local regulations.

GUARDS MUST NOT BE REMOVED WHILE THE PUMP IS OPERATIONAL The unit must not be operated unless coupling guard is in place. Failure to observe this warning could result in injury to operating personnel.

THERMAL SHOCK Rapid changes in the temperature of the liquid within the pump can cause thermal shock, which can result in damage or breakage of components and should be avoided.

NEVER APPLY HEAT TO REMOVE IMPELLER Trapped lubrican t or vap our could c ause an ex plosion .

HOT (and cold) PARTS If hot or freezing components or auxiliary heating supplies can present a danger to operators and persons entering the immediate area action m ust be taken to avoid accidental contact. If complete protection is not possible, the machine access must be limited to maintenance staff only, with clear visual warnings and indicators to those entering the immediate area. Note: bearing housings must not be insulated and drive motors and bearings may be hot.

If the temperature is greater than 80 °C (175 °F) or below -5 °C (20 °F) in a restricted zone, or exceeds local regulations, action as above shall be taken.

1.6.4 Products used in potentially explosive atmospheres

Measures are required to:

 Avoid excess temperature.  Prevent build up of explosive mixtures.  Prevent the generation of sparks.  Prevent leakages.  Maintain the pump to avoid hazard.

The following instructions for pumps and pump units when installed in poten tially exp losive at mosph eres must be followed to help ensure explosion protection. Both electrical and non-electrical equipment must meet the requirements of European Directive 94/9/EC.

1.6.4.1 Scope of compliance

Use equipment only in the zone for which it is appropriate. Always check that the driver, drive coupling assembly, seal and pump equipment are suitably rated and/or certified for the classification of the specific atmosphere in which they are to be installed.

Where Flowserve has supplied only the bare shaft pump, the Ex rating applies only to the pump. The party responsible for assembling the pump set shall select the coupling, driver and any additional equipment, with the necessary CE Certificate/ Declaration of Conformity establishing it is suitable for the area in which it is to be installed.

The output from a variable frequency drive (VFD) can cause additional heating affects in the motor and so, for pumps sets with a VFD, the ATEX Certification for the motor must state that it is covers the situation where electrical supply is from the VFD. This particular requirement still applies even if the VFD is in a safe area.

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

1.6.4.2 Marking

An example of ATEX equipment marking is shown below. The actual classification of the pump will be engraved on the nameplate.

II 2 GD c IIC 135 ºC (T4)

Equipment Group I = Mining II = Non-mining

Category 2 or M2 = High level protection 3 = normal level of protection

Gas and/or Dust G = Gas; D = Dust

C = Constructional safety (in accordance with En13463-5)

Gas Group (Equipment Category 2 only) IIA – Propane (typical) IIB – Ethylene (typical) IIC – Hydrogen (typical)

Maximum surface temperature (Temperature Clas s ) (See section 1.6.4.3.)

1.6.4.3 Avoiding excessive surface temperatures

ENSURE THE EQUIPMENT TEMPERATURE CLASS IS SUITABLE FOR THE HAZARD ZONE Pumps have a temperature class as stated in the ATEX Ex rating on the nameplate. These are based on a maximum ambient of 40 °C (104 °F); refer to Flowserve for higher ambient temperatures.

The surface temperature on the pump is influenced by the temperature of the liquid handled. The maximum permissible liquid temperature depends on the temperature class and must not exceed the values in the table that follows.

The temperature rise at the seals and bearings and due to the minimum permitted flow rate is taken into account in the temperatures stated.

The responsibility for compliance with the specified maximum liqu id temperature is with the plant operator.

Temperature classification “Tx” is used when the liquid temperature varies and the pump could be installed in different hazardous atmospheres. In this case the user is responsible for ensuring that the pump surface temperature does not exceed that permitted in its actual installed location.

If an explosive atmosphere exists during the installation, do not attempt to check the direction of rotation by starting the pump unfilled. Even a short run time may give a high temperature resulting from contact between rotating and stationary components.

Where there is any risk of the pump being run against a closed valve generating high liquid and casing external surface temperatures it is recommended that users fit an external surface temperature protection device.

Avoid mechanical, hydraulic or electrical overload by using motor overload trips, temperature monitor or a power monitor and make routine vibration monitoring checks.

In dirty or dusty environments, regular checks must be made and dirt removed from areas around close clearances, bearing housings and motors.

1.6.4.4 Preventing the build up of explosive mixtures

ENSURE THE PUMP IS PROPERLY FILLED

AND VENTED AND DOES NOT RUN DRY. Ensure the pump and relevant suction and discharge

pipeline system is totally filled with liquid at all times during the pump operation, so that an explosive atmosphere is prevented. In addition it is essential to make sure that seal chambers, auxiliary shaft seal systems and any heating and cooling systems are properly filled.

If the operation of the system cannot avoid this condition the fitting of an appropriate dry run protection device is recommended (eg liquid detection or a power monitor). To avoid potential hazards from fugitive emissions of vapour or gas to atmosphere the surrounding area must be well ventilated.

Page 7 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

1.6.4.5 Preventing sparks

To prevent a potential hazard from mechanical contact, the coupling guard must be non-sparking and anti-static for Category 2.

To avoid the potential hazard from random induced current generating a spark, the earth contact on the base plate must be used. Avoid electrostatic charge: do not rub non-metallic surfaces with a dry cloth ensure cloth is damp. The coupling must be selected to comply with 2006/42/EC and correct alignment must be maintained.

1.6.4.6 Preventing leakage

The pump must only be used to handle liquids for which it has been approved to have the correct corrosion resistance. Avoid entrapment of liquid in the pump and associated piping due to closing of suction and discharge valves, which could cause dangerous excessive pressures to occur if there is heat input to the liquid. This can occur if the pump is stationary or running. Bursting of liquid containing parts due to freezing must be avoided by draining or protecting the pump and ancillary systems. Where there is the potential hazard of a loss of a seal barrier fluid or external flush, the fluid must be monitored. If leakage of liquid to atmosphere can result in a hazard, the installation of a liquid detection device is recommended.

1.6.4.7 Maintenance to avoid the haz ard

1.7 Nameplate and safety labels

1.7.1 Nameplate

For details of nameplate, see the Declaration of Conformity, or separate documentation included with

these User Instructions.

1.7.2 Safety labels

CORRECT MAINTENANCE IS REQUIRED TO AVOID POTENTIAL HAZARDS WHICH GIVE A RISK OF EXPLOSION

The responsibility for compliance with maintenance instructions is with the plant operator.

To avoid potential explosion hazards during maintenance, the tools, cleaning and painting materials used must not give rise to sparking or adversely affect the ambient conditions. Where there is a risk from such tools or materials; maintenance must be conducted in a safe area. It is recommended that a maintenance plan and schedule is adopted. (See section 6, Maintenance.)

1.8 Specific machine performance

For performance parameters see section 1.5, Duty conditions. Pump performance data are summarised

on pump data sheet which is included in proper section of “Job User’s Instruct ion”.

1.9 Noise level

When pump noise level exceeds 85 dBA attention must be given to prevailing Health and Safety Legislation, to limit the exposure of plant operating personnel to the noise. The usual approach is to control exposure time to the noise or to enclose the

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

machine to reduce emitted sound. You may have already specified a limiting noise level when the equipment was ordered, however if no noise requirements were defined then machines above a certain power level will exceed 85 dBA. In such situations consideration must be given to the fitting of an acoustic enclosure to meet local regulations.

If a pump unit only has been purchased, for fitting with your own driver, then the "pump only" noise levels should be combined with the level for the driver obtained from the supplier. If the m otor is driven by an inverter, it may show an increase in noise level at some speeds. Consult a Noise Specialist for the combined calculation.

Pump noise level is dependent on a number of factors - the type of motor fitted, the operating conditions, pipework design and acoustic characteristics of the building. The levels specified in the table 1.1 are estimated and not guaranteed.

The dBA values are based on the noisiest ungeared electric motors that are likely to be encountered. They are Sound Pressure levels at 1 m (3.3 ft) from the directly driven pump, for "free field over a reflecting plane".

 For units driven by equipment other than

electric motors or units contained within enclosures, see the accompanying information sheets and manuals.

To lift machines or pieces with one or several suspension rings, only use hooks and chains in compliance with the local regulations concerning safety. Never put cables, chains or ropes directly on or in the suspension rings. Cables, chains or lifting ropes must never present excessive bending.

Never bend the lifting hooks, suspension rings, chains, etc., which should only be made to endure stresses within, calculated limits. Remember that the capacity of a lifting device decreases when the direction of the lifting force direction makes an angle with the device axis.

To increase the safety and the efficiency of the lifting device, all the lifting elements must be as perpendicular as possible. If necessary a lifting b eam can be placed between the winch and the load. When heavy pieces are lifted up, never stay or work under the load or in the area, which could be in the path of the load if it were to swing or fall away.

Never leave a load hanging from a winch. The acceleration or the slowing-down of lifting equipment must stay in the safety limits for the staff.

A winch must be positioned in such a way that the load will be raised perpendicularly. Where possible necessary precautions must be taken to avoid the swing of the load, using for example two winches making approximately the same angle, below 30°, with the vertical.

2.3 Lifting

Make sure that any equipment used to lift the pump or any of its components is capable of supporting the weights encountered. Make sure that all parts are correctly rigged before attempting to lift.

A crane must be used for all pump sets in excess of 25 kg (55 lb). Fully trained personnel must carry out lifting, in accordance with local regulations. The driver and pump weights are recorded on general arrangement drawing included into the job user’s instruction.

2.3.1 To Lift unit

Pump, driver and baseplate can be lifted as a unit. Sling from all four (4) eye bolts provided on baseplate side rails. Failure to use all four (4) could result in permanent distortion of the baseplate. Use as long a sling as possible, or use a spreader arrangement.

Coupling bolting and spacer piece

must be removed from between pump and driver half couplings before lifting baseplate with pumping element. To lift pump and baseplate, less driver, or baseplate alone, sling from all four (4) eye bolts.

Do not lift pump, motor, base plate unit by slinging from pump casing and/or eye bolt on motor.

2.3.2 To lift driver

Refer to Manufacturers Instructions.

2.3.3 To lift complete pump only

Rig lifting straps at coupling end bearing bracket and outboard bearing bracket. Make sure straps are adjusted to obtain an even lift.

2.4 Storage

Store the pump in a clean, dry location away from vibration. Leave piping connection covers in place to keep dirt and other foreign material out of pump casing. Turn pump at intervals to prevent brinelling of the bearings and the seal faces, if fitted, from sticking. Electric Motors (Pump Driver) should not be stored in damp places without special protection (Refer to Motor manufacturers instructions).

The pump may be stored as above for up to 6 months.

2.4.1 Long term storage

During extended periods of storage prior to installation, precautions must be taken to protect the pump from deterioration. The various parts of the pump are protected prior to shipment by applying varying grades of preservative to the parts. However, during shipment and handling the preservatives are subjected to conditions that can cause their removal. Also, during extended periods of time the preservatives may deteriorate. The listed procedures (2.4.1.1 to 2.4.1.5) should be followed to prevent deterioration of the pump during the extended storage period. These procedures may also be supplemented by the experience of the person(s) performing the tasks.

2.4.1.1 Inspection upon arrival

When the pump is received it should be inspected for damage or other signs of rough handling. If any damage is found it should be reported to the carrier immediately. Inspect the preservative coating on various parts. If necessary, renew preservative in areas where it has been rubbed or scraped. Inspect all painted surfaces. If necessary, touch up the areas where paint has been chipped or scraped.

Inspect all covers over pump openings and piping connections. If covers or seals for the covers are damaged or loose, they are to be removed, and a visual inspection made of the accessible interior areas for accumulation of foreign materials or water. If necessary, clean and preserve the interior parts as noted above to restore the parts to the "as sh ipped" condition. Install or replace covers and fasten securely.

2.4.1.2 Storage

If at all possible, the pump and its

component parts should be stored indoors where they will be protected from the elements. In no case should any pump element be subjected to extended periods of submergence or wetting prior to start up. If it is not possible to store the pump and its components indoors, precautions must be taken to protect them from the elements. Regardless of whether storage is indoors or outside, the storage area should be vibration free. All boxes marked for indoor storage should be stored indoors. When stored outdoors the pump and its components should be protected from dirt, dust, rain, snow, or other unfavourable conditions by heavy plastic sheets, canvas, waterproof burlap or other suitable coverings. All equipment must be placed upon skids or blocks to prevent contact with the ground and surface contaminants. Equipment must be adequately supported to prevent distortion and bending. The pump shaft should be rotated, in the direction of rotation, at least 1 and 1/4 turns each week during the storage period and any other periods of stand by. When selecting a storage area the following should be taken into consideration.

a) The deterioration of the equipment will be

proportionate to the class of storag e pr ov ide d.

b) The expenses involved in restoring the

equipment at time of installation will be proportionate to the class of storag e pr ov ide d.

2.4.1.3 Inspection and maintenance

The stored equipment has to be placed on a periodic inspection schedule by the purchaser. The responsibility for setting up an inspection schedule rests with the purchaser and will be dependent upon the class of storage provided. It would be expected initially, inspection would occur weekly, then depending upon the inspection reports being favourable or unfavourable, inspection would continue weekly, monthly, or quarterly, as may be determined.

Page 11 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

Each inspection should consist of a general surface inspection to assure that:

a) Pump supports are firmly in place. b) Pump covers over openings are firmly in place. c) Pump coverings, plastic or tarps are firmly in

place. Any holes or tears must be repaired to prevent entrance of dirt or water.

d) Pump covers are periodically removed from

openings and interior accessible areas inspected. If surface rusting has occurred, clean or coat with preservative.

e) If rusting occurs on exterior surfaces clean and

repaint or coat with preservative.

f) Check individually wrapped parts for signs of

deterioration. If necessary, renew preservative and wrapping.

Six months prior to the scheduled installation date, a FLOWSERVE representative is to be employed to conduct an inspection. This inspection may include, not necessarily in its entirety and not limited to the following:

a) An inspection of all periodic inspection r ecords as

kept on file by the purchaser, and all inspection reports that have been compiled during the storage period.

b) An inspection of the storage area to determine

the "as stored" condition of the equipment prior to any protection covers being removed.

c) An inspection of the equipment with protective

covers and flange covers removed.

d) Depending upon the length of time the equipment

was stored, the type of storage provided (i.e. Indoor: heated, unheated, ground floor, concrete floor. Outdoors: under roof, no roof, waterproof coverings, on concrete, on ground) and as a result of the inspection of (a),( b) & (c) above the FLOWSERVE representative may require a partial or complete dismantling of the equipment.

e) Dismantling may necessitate restoration of

painted or preserved surfaces, and, or replacement of gaskets, "O" rings, packing and bearings.

f) All costs involved during inspection, dismantling,

restoration, replacement of parts and reassembly will have to the accounted to the purchaser. All necessary labour, tools and cranes will be supplied by the purchaser.

Upon completion of the inspection the FLOWSERVE representative shall submit a report to the purchaser, and to the Manager of Customer Service, stating in detail the results of the inspection.

One month prior to installation of the equipment, a FLOWSERVE representative is to be employed to conduct a final inspection. This inspection will be made to assure that the requirements of the six months inspection report were satisfactorily completed and that the equipment is ready for installation. Upon completion of this inspection the FLOWSERVE representative shall submit a final report to the purchaser, and to the Manager of Customer Service, advising the results of the final inspection. All costs involved in conducting the final inspection will have to the accounted to the purchaser. Prior to and during start up, any requirements for the services of an FLOWSERVE representative will revert back to the original contract agreement for equipment purchased, with revised costing.

2.4.1.4 Painting and preservation

Paints and preservatives used are either FLOWSERVE standard or 'special' as required by the contract specification. Refer to FLOWSERVE for the description of paints and preservatives used on this order if needed.

2.4.1.5 Associated equipment

Motors, Turbines, Gears, etc., being supplied by FLOWSERVE. Generally rotors of associated equipment should be blocked to relieve bearing loads. Storage should be indoors and dry. See the specific manufacturers storage requirement s.

2.5 Recycling and end of product life

At the end of the service life of the product or its parts, the relevant materials and parts should be recycled or disposed of using an environmentally acceptable method and local regulations. If the product contains substances which are harmful to the environment, these should be removed and disposed of in accordance with current regulations.

3 PUMP DESCRIPTION

3.1 Configurations

HED pumps are horizontal two stage, radially split, top/top flanged, between bearings centerline mounted for heavy duty process services in full compliance with API 610 standard. All sizes are suitable for both 50 and 60 cycle operation. To reduce NPSH requirements the HED can be fitted with an inducer in front of the first impeller (HED-I) or with a double suction first stage (HED-DS).

3.2 Nomenclature

The pump size will be engraved on the nameplate typically as below:

6-HED-17-A

Nominal discharge branch size Pump type Nominal full size impeller diameter Casing pattern type The typical nomenclature above is the general guide

to the HED/HED-DS description. Identify the actual pump size and serial number from the pump nameplate. Check that this agrees with the applicable certification provided.

3.3 Design of major parts

3.3.1 Pump casing

The casing is radially split with top suction and discharge nozzles integrally cast. This construction simplifies piping layout reducing space requirements. Side/side or side/top arrangements are available on request for particular applications. The mounting is centerline to retain alignment even at elevated temperatures, permitting equal expansion in all directions, and to give positive support to the pump. The first and second stage single volutes are opposed to reduce hydraulic radial thrust and shaft deflection, and the liquid is conveyed from the one to the other by an integral cast crossover. The interstage diaphragm too is integrally cast with the casing. All the flow passages are accurately designed to minimize efficiency losses.

3.3.2 Impeller

The standard impellers, single suction of the closed type, are keyed to the shaft and secured by positive

locking devices. They are mounted face to face to balance the hydraulic axial forces. Impellers first and then the complete rotor are dynamically balanced to avoid vibrations and assure long trouble free life to seals and bearings. Ceramic core castings are used to assure smooth passages and the highest efficiency. Large eye areas and low-entrance velocities give the pump very low NPSH requirements, when extremely low NPSH requirements are encountered, HED pumps can be fitted with an inducer or with a double suction first stage impeller. Some pump sizes have more than one impeller design, with differentiated B.E.P. capacities, for maximum flexibility and operation with high efficiencies throughout the coverage.

3.3.3 Wearing Rings

The casing and the impellers are fitted with replaceable wear rings of hardened material. The rings are held in place by a press fit with locking pins on the casing and with threaded dowels on the impellers.

3.3.4 Rotors

Rotors are of the stiff shaft design. Shafts are of ample diameter, combined with the minimum bearing span to minimize shaft deflectors especially when the pump is operating at off peak conditions. Shafts are designed to meet API 610 deflection and vibration requirements. Fully assembled rotors are dynamically balanced can accommodate a wide variety of single or dual seal arrangements as standard.

3.3.5 Casing Covers

Two covers, one full size at the outboard pump end which permits rotor removal and one reduced size cover at inboard end provide circular type joints and easy pump sealing with confined gaskets. The metal to metal fit with confined controlled compression gasket insures proper alignment between casing and cover.

3.3.6 Bearing Housings

HED/HED-DS pumps are fitted as standard with antifriction bearings. The radial bearing is a deep groove type, while the thrust bearings are dual single row angular contact type. Lubrication is provided by an oil slinger in conjunction with a TRICO constant level oiler, both provided as standard. In case of particularly severe operating conditions sleeve line with antifriction or tilting pad thrust bearing are available with self-contained or external lube system.

Page 13 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

Special bearing isolators (INPROSEAL or equivalent) are available on request. Bearing housings can also be adapted for optional oil mist or purge mist lubrication systems.

3.3.7 Shaft seals

The mechanical seals, attached to the pump shaft, seals the pumped liquid from the environment.

3.3.8 Driver

The driver is normally an electric motor. Different drive configurations may be fitted such as internal combustion engines, turbines, hydraulic motors etc driving via couplings, belts, gearboxes etc.

3.3.9 Coupling/Coupling guards

Flexible spacer couplings are provided in various makes and models to suit custome r preference. (Aluminium non- hinged guards are provided).

3.3.10 Baseplate

Standard baseplates are welded steel, drain pan type in conformance with API 610 standardized dimensions. Horizontal driver alignment screws and vertical baseplate leveling screws are provided when required by API. Special baseplates can be supplied to suit individual installation circumstances.

3.3.11 Accessories

Accessories may be fitted when specified by the customer. Baseplates are fabricated and machined so to guarantee the flatness and parallelism of pads as required by API standard. The requirement is met by supporting and clamping the baseplate at the foundation bolt holes only.

3.4 Performance and operating limits

This product has been selected to meet the specifications of your purchase order see section 1.5. These pumps are furnished for a particular service condition. Changes in the hydraulic system may affect the pump's performance adversely. This is especially true if the changes reduce the pressure at the suction flange or if the liquid temperature is increased. In case of doubt, contact the nearest FLOWSERVE office.

3.4.1 Effect of specific gravity

Pump capacity and total head in meters (feet) do not change with SG, however pressure displayed on a pressure gauge is directly proportional to SG. Power absorbed is also directly proportional to SG. It is therefore important to check that any change in SG

will not overload the pump driver or over-pressurize the pump.

3.4.2 Effects of viscosity

The pump is designed to deliver rated capacity and rated head for a liquid with a particular viscosity. For a given flow rate the total head reduces with increased viscosity and increases with reduced viscosity. Also for a given flow rate the power absorbed increases with increased viscosity, and reduces with reduced viscosity. When contemplating operation at some viscosity other than the one for which the pump was originally designed and/or applied, the changed conditions should be referred to FLOWSERVE for recommendations.

When pump is handling heavy

viscous liquid, the temperature of the liquid must allow it to be pumped easily. Liquid may have to be heated prior to pump start-up.

3.4.3 Changing the pump speed

Changing pump speed effects flow, total head, power absorbed, NPSH

, noise and vibration. Flow varies in

direct proportion to pump speed. Head varies as speed ratio squared. Power varies as speed ratio cubed. If increasing speed it is important therefore to ensure the maximum pump working pressure is not exceeded, the driver is not overloaded, NPSH

>NPSHR, and that noise and vibration are

within local requirements and regulations.

3.4.4 Net Positive Suction Head (NPSH)

Any liquid, hot or cold, must be pushed into the impeller of the pump by absolute pressure, such as the atmospheric or vessel pressure from which the pump takes its suction. The head in feet of liquid necessary to push the required flow into the pump is called Net Positive Suction Head. This value, more commonly called NPSH, is measured above the vapour pressure of the liquid at the pumping temperature. There are two kinds of NPSH: the NPSH

is the head

required by the pump to cover the losses in the pump suction - that is shown on the pump characteristic curve. The second, NPSH

, is the head available in the

system, taking into account friction loss in suction piping, valves, fittings etc. In all cases the NPSH

measured above vapour pressure, must exceed the NPSH

in order to push the liquid into the pump.

Failure to have this will result in both bad performance and mechanical damage to the pump, and in certain cases actual pump failure.

Page 14 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

If any change in NPSHA is proposed, ensure its margin over NPSH to the pump performance curve to determine exact requirements particularly if flow has changed. If in doubt please consult your nearest Flowserve office for advice and details of the minimum allowable margin for your application.

3.4.5 Minimum Continuous Stable Flow

The Minimum Continuous Stable Flow for the pump is stated on the Data sheet.

3.4.6 Minimum flow control

In all cases, it is the customer's responsibility to supply a system and/or control which assures that any pump within a system is not operated below its minimum flow condition. In many cases, this is not a problem because the system is operating within its own flow range to assure product delivery. A simple high pressure alarm, shut down and/or bypass control can be used . However, in systems where product demand has high swings or where more than 100% capacity units are desired to support a product system, additional care must be taken.

3.4.7 Thermal control

A thermal control of the unit can be provided by thermal sensors which read direct or "related to" fluid temperatures and respond accordingly by opening additional flow paths until the given unit reestablishes the acceptable temperature rise, and sets off alarms if not achieved within reasonable/normal time periods. (High limit could actually shut down unit).

3.4.8 Pressure and/or Flow Control

Pressure and/or flow sensors can be used to hold the unit at higher flows by opening additional flow paths once a "high pressure limit" or " low flow limit" was indicated. Upon system reaching increased flow a "low pressure limit" or "high flow limit" setting would close the bypass flow path. Care must be taken to allow for signal spread to avoid cyclic conditions.

3.4.9 Operating at Reduced Capacity

prolonged operations at capacities less than MCSF as stated in Data Sheet.

is not significantly eroded. Refer

Damage to pump may result from

4 INSTALLATION

Equipment operated in hazardous locations

must comply with the relevant explosion protection

regulations. See section 1.6.4, Products used in

potentially explosive atmospheres.

4.1 Location

The pump should always be located as near as possible to the suction supply. Install the unit close to the source of the liquid to be pumped. It is desired to simplify the suction and discharge piping layout. When selecting the location, be sure to allow adequate space for operation as well as for maintenance operations involving dismantling and inspections of parts. Head room is an important consideration as an overhead lift of some type is required

4.2 Part assemblies

Motors may be supplied loose. It is the responsibility of the installer to ensure that the motor is assembled to the pump and lined up as detailed in section 4.5.2.

Prior to grouting, an initial alignment check in accordance with the alignment section of this document shall be performed to verify that coupling spacing and final alignment can be achieved without modifying the hold down bolts or the machine feet. This is necessary to ensure that the baseplate was not damaged during the transportation.

4.3 Foundation

There are many methods of installing pump units to their foundations. The correct method depends on the size of the pump unit, its location and noise vibration limitations. Non-compliance with the provision of correct foundation and installation may lead to failure of the pump and, as such, would be outside the terms of the warranty. The foundation should be sufficiently rigid and substantial to prevent any pump vibration and to permanently support the baseplate at all points.

The most satisfactory foundations are made of reinforced concrete. These should be poured well in advance of the installation to allow sufficient time for drying and curing. The General Arrangement Drawing (In Job’s User Instruction) will furnish overall outline of pump baseplate, anchor bolt locations, size of bolts, etc in order to provide proper shape to the primary concrete. Anchor bolts can be positioned or by a special template (not supplied by FLOWSERVE see figure 4.1) or by the baseplate itself if proper pockets have been provided in primary concrete.

Template for Hanging Foundation Bolts

Figure 4.1

Figure 4.2 below illustrates an alternative foundation bolt arrangement which can be used in lieu of standard foundation bolts. Notice the large washer with lugs at the bottom. It should be welded to the bolt and pipe sleeve to prevent turning. Allow a little more than the specified threaded bolt length above the rail of the baseplate. The excess can always be cut off if it is not needed. A rough finish top surface is best when applying grout.

ALLOW AMPLE THREADED BOLT LENGTH ABOVE ROUGH CONCRETE

ROUGH FINISH

STUFF WASTE AROUND BOLT WHILE POURING CONCRETE

FOR GROUT

In case of installation over a steel structure (platform) ensure that the top of the steel structure is cleaned and degreased.

In order to obtain the parallelism and flatness of pads required by API standard, baseplate has to be properly levelled by levelling screws provided on it and clamping the baseplate at the foundation bolts only (For proper detailed procedure refer to Chapter 5 para 3.9.4 of API RP 686 ).

Coupling bolting and spacer piece must be removed from between the pump and driver half couplings before lifting baseplate with pumping element.

When the unit is mounted directly on structural steel framing, it should be located directly over as near as possible to the main building members, beams, or walls. A soleplate should be bolted or welded to the steel frame to guara ntee the proper surface.

When lifting baseplate with pumping element, sling baseplate from all lifting lugs provided. Refer to Section 2.3.1

Prepare sufficient steel plates to be placed below each baseplate jacking screw furnished with the baseplate. The purpose of the plate is to spread the load of the screw without crushing the concrete below.

4.3.2 Method of levelling baseplate using wedges or shims

a) Level the baseplate by using a machinist's level

on the machined surfaces of the pump and driver

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

pads. Levelling is best achieved by adjusting the shim pack thickness under each holding bolt. Carefully raise the baseplate by using eith er the baseplate jacking screws provided or by levering with a suitable pinch bar or by installing a low level hydraulic jack.

b) Adjust the shim pack thickness and lower the

baseplate.

c) Repeat this procedure in a logical manner at

each bolt position until the baseplate is both straight and levelled. A degree of 0.25 mm per metre (0.0035 inch per foot) length is achievable on most units with a maximum of 0.40 mm per meter length (0.005 inch per foot).

d) In case of installation on steel structures (like

platforms) proceed with these extra steps:  Using a calibrated pin with a cone p oint mark

the centre of baseplate support pads mounting holes on the soleplate.

 Lift and move away the pump skid.  Drill and tap the soleplate fixing holes.  Replace the pump skid so that the soleplate

fixing holes align with the baseplate support pads mounting holes.

 Level the unit like done previously (see points

a, b, c).

e) When the baseplate is level, pull down the

foundation bolts so they are snug or tighten the fixing bolts in case of installation on steel structure. This may have disturbed the baseplate,

so re-check the levels. Ensure that shaft alignment per Section 4.5 can be achieved prior to grouting the baseplate.

4.4 Grouting

Build a dam around the foundation as shown in Figure 4.4 after levelling the baseplate. It is a matter of personal preference whether the levelling wedges under the baseplate should be removed after grouting. If you do not want to remove the wedges, carefully mark their locations before pouring grout.

Before grouting, level machined

pads of baseplate in both directions and perform a rough shaft/coupling alignment. Alignment after grout has set will not be possible if above is not satisfactorily completed.

Use a good, high strength, non shrink grout mix and install as per manufacturer's instructions. Holes are provided in the baseplate to permit pouring the grout and stirring while acting as air vents. Fill under the baseplate completely, stirring to assure correct distribution of the grout. Check to see that the grout flows under the edges of the base plat e even ly.

Do not vibrate baseplate when grouting, making sure baseplate is vented correctly and all areas are thoroughly puddle to preven t any resonant problems. When the grout is thoroughly hardened, remove the dam and wedges, if desired, filling in the holes they leave with grout.

Pour grout until level reaches top of dam. Allow to dry sufficiently to prevent grout from overflowing while completing the remaining grouting.

4.4.2 Baseplate not Intended for Grouting but Installed on Concrete Foundations

According to the figure 4.3.1 and 4.4.1 the baseplate will not be grouted but only a sealing shall be provided. During the preparation, as indicated on the General Arrangement drawing a certain number of openings into the sealing must be guaranteed. After the sealing the blocks used to realise the openings must be removed. Blocks have to be wider than the baseplate longitudinal beam in order to guarantee the opening for the drainage.

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

4.5.2.1 Shaft/Coupling alignment

Shaft alignment must be correct for

successful operation. Rapid wear, noise, vibration and actual damage to the equipment may be caused by shaft misalignment. The shafts must be aligned within the limits given within this

section.

Adjustment to correct the alignment in one direction may alter the alignment in another direction. Always check in all directions after making any adjustment. Coupled equipment must be aligned to minimise unnecessary stresses in shafts, bearings and coupling. Flexible couplings will not compensate for appreciable misalignment. Foundation settling, thermal expansion or nozzle loads resulting in baseplate/foundation deflection and vibration during operation may require the full coupling misalignment capability.

4.5.2.1.1 Types of misalignment

There are two types of shaft misalignment: angular and offset. Therefore, two sets of measurements and corrections are required. Both types of misalignment can occur in horizontal and vertical planes and are present in most applications.

A) Angular misalignment In angular misalignment, the centre line of the shafts intersects, but are not on the same axis.

The pump and motor will normally have to be aligned at ambient temperature and should be corrected to allow for thermal expansion at operating temperature.

4.5.2 Alignment methods

Ensure pump and driver are isolated

electrically and the half couplings are disconnected

Page 18 of 64

Figure 4.7

B) Offset misalignment In offset misalignment, the shaft centre lines are parallel but do not intersect.

Figure 4.8 – offset misalignment

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

Figure 4.9 – combination of offset and angular misalignment

4.5.2.2 Alignment using the reverse dial Indicator

The following practices are recommended when using the reverse method of alignment. These should be carried out prior to main alignment.

The alignment MUST be checked. Although the pump will have been aligned at the factory it is most likely that this alignment will have been disturbed during transportation or handling. If necessary, align the motor to the pump, not the pump to the motor. The alignment is achieved by adding or removing shims under the motor feet and also moving the motor horizontally as required. In some cases where the alignment cannot be achieved it will be necessary to move the pump before recommencing the above procedure.

For couplings with narrow flanges use a dial in dicator as shown on figure 4.11 to check both parallel and angular alignment.

For detailed alignment procedure refer to API RP686.

Figure 4.10

CHECK FOR SOFT FOOT This is a check to ensure that there is no undue

stress on the driver holding down bolts; owing to nonlevel baseplate or twisting. To check, remove all shims and clean surfaces and tighten down driver to the baseplate. Set a dial indicator as shown in sketch and loosen off the holding down bolt while noting any deflection reading on the Dial Test Indicator - a maximum of 0.05 mm (0.002 in.) is considered acceptable but any more will have to be corrected by adding shims, for example, if the Dial Test Indicator shows the foot lifting 0.15 mm (0.006 in.) then this is the thickness of shim to be placed under that foot. Tighten down and repeat the same procedure on all other feet until all are within tolerance.

If the driver is an electric motor with sleeve bearings then the magnetic centre at which the rotor will run must be set. This is usually done by lining up a groove in the shaft to a pointer fixed to the motor body (refer to Motor Manufacture’s instructions).

Ensure pump and driver are isolated

electrically and the half couplings are disconnected.

Figure 4.11

Maximum permissible misalignment at working temperature: Parallel 0.05 mm (0.002 in.) TIR Angular 0.05mm/100mm (0.0005In/In)

Pumps with thick flanged non-spacer couplings can be aligned by using a straight-edge across the outside diameters of the coupling hubs and measuring the gap between the machined faces using feeler gauges, measuring wedge or calipers.

When the electric motor 4has sleeve bearings it is necessary to ensure that the motor is aligned to run on its magnetic centreline.

 Refer to the motor manual for details.

A button (screwed into one of the shaft ends) is normally fitted between the motor and pump shaft ends to fix the axial position.

Page 19 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

If the motor does not run in its magnetic centre the resultant additional axial force may overload the pump thrust bearing.

Complete piping as below and see sections 4.7, “Final shaft alignment check” up to and including section 5, “Commissioning, start-up, operation and shutdown” before connecting driver and checking actual rotation.

4.5.3 Shims

The shims between the equipment feet and mounting surface should be clean and dry. This is especially critical for pumps in service for sometime and need to be realigned. Water, dirt and rust may change the height of the shim pack over a period of time. Shim s should be made large enough to support the weight of the equipment on its mounting foot. Do not use many thin shims as this may result in a spongy mounting.

Figure 4.12

Recommended shim design

Move the equipment vertically by adding or removing the calculated thickness of shims. Torque holding down bolts to required values.

4.5.4 Hot alignment – Pump and driver dowels

Pump hold down bolts are to be torqued down and dowel pins are to be located in pump feet. (This is only applicable if Hot Alignment is required). Refer to driver outline drawing and/or driver instructions for driver doweling information. A hot check can only be made after the unit has been in operation a sufficient length of time to assume its NORMAL operating temperature and conditions. If the unit has been correctly cold set, the offset misalignment will be within within the limits stated on

par 4.5.2.2 when in operation.

If not make adjustments.

Do not attempt any maintenance,

inspection, repair or cleaning in the vicinity of rotating equipment. Such action could result in injury to operating personnel.

Before attempting any inspection or repair

on the pump the driver controls must be in the "off" position, locked and tagged to prevent restarting equipment and injury to personnel performing service on the pump.

4.5.5 Assemble coupling

a) Assemble coupling as per the manufacturer's

instructions included in Appendix of this manual.

b) Install coupling guard

4.5.6 Installation check list

a) Level Baseplate? b) Grout Baseplate - Check Foundation Bolts? c) Alignment Shaft/Coupling? d) Piping Installed - Correct Vent, Gauge, Valve,

Suction Strainer Locations?

e) All Flange Bolting Correctly Torqued with

appropriate gaskets in place? f) Check Shaft/Coupling Alignment again. g) Coupling guard correctly installed ?

4.6 Piping

Never use the pump as a support for

piping.

4.6.1 General

These units are furnished for a particular service condition. Changes in the hydraulic system may affect performance adversely. This is especially true if the changes reduce the pressure at the suction or if the liquid temperature is increased. In case of doubt contact FLOWSERVE. Suction and discharge piping should be of ample size, be installed in direct runs, and have a min imum of bends. Double bends must be avoided in suction line and a straight run of pipe, equal 7 to 10 times the pipe diameter is desired directly upstream of the suction nozzle. In order to minimize friction losses and hydraulic noise in the pipework it is good practice to choose pipework that is one or two sizes larger than the pump suction and discharge. Typically main pipework velocities should not exceed 2 m/s (6 ft/sec) suction and 3 m/s (9 ft/sec) on the discharge.

Provision must be made to support piping external to the pump to prevent excessive nozzle loads, maintain pump/driver alignment and avoid pipe induced vibrations.

Take into account the available NPSH which must be higher than the required NPSH of the pump.

Page 20 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

Maximum forces and moments allowed on the pump flanges vary with the pump size and type. To minimize these forces and moments that may, if excessive, cause misalignment, hot bearings, worn couplings, vibration and the possible failure of the pump casing, the following points should be strictly followed:

 Prevent excessive external pipe load.  Never draw piping into place by applying force to

pump flange connections.

 Do not mount expansion joints so that their force,

due to internal pressure, acts on the pump flange.

Ensure piping and fittings are flushed

before use.

Ensure piping for hazardous liquids is arranged

to allow pump flushing before removal of the pump.

4.6.2 Suction Piping

a) The inlet pipe should be one or two sizes larg er

than the pump inlet bore and pipe bends should be as large radius as possible.

b) Keep the suction pipe free of all air pockets.

(Vent is required).

c) Pipework reducers should have a maximum tota l

angle of divergence of 15 degrees.

d) Use only eccentric reducers with the straight side

on the top.

e) Flo w should enter the pump suction with uniform

flow, to minimize noise and wear. f) A gate valve is recommended in the suction line. g) Except if considerable foreign matter is expected

strainers are not recommended in inlet piping.

Inlet strainers, when used, should have a net

“free area” (see section 4.6.2.1)

4.6.2.1 Suction Strainer

It is recommended that a temporary strainer be placed in the suction pipe to prevent lodging of foreign material in the impeller. A pipe spool of sufficient size should be provided with gauge taps to accommodate the suction strainer. The strainer should be installed as close to the pump as possible. The open area of the strainer should have a minimum of a 3 to 1 ratio to the area of the pump inlet. Pressure gauges should be installed on both sides of the strainer, so the pressure drop across the strain er can be measured when the unit is operated.

Typical temporary suction strainer

Pressure gauges should be installed on both sides of the screen so that the pressure drop across the screen can be measured. When the unit is being started, the gauges on each side of the screen should be carefully watched. An increase in the differential pressure between the two gauges indicates that the screen is becoming clogged with dirt and scale. At this point, the pump should be shut down, and the screen cleaned and/or replaced.

A spool piece should be installed in suction line so that the suction strainer may be installed and removed with a pressure gauge between the strainer and pump.

4.6.2.2 Bypass Line

Operation at low flows results in

pump horsepower heating the liquid. A bypass may be required to prevent vaporization and subsequent pump damage. Refer to local FLOWSERVE branch to determine if a bypass is required. Mechanical damage may result from continuous operation at flows less than specified.

4.6.3 Discharge piping

a) Install a check valve and a gate valve in the

discharge pipe of the pump. When the pump is stopped, the check valve will protect the pump against excessive pressure and will prevent the pump from running backward. The check valve should be installed between the gate valve and the pump nozzle in order to permit its inspection. Never throttle pump on suction side and never place a valve directly on the pump inlet nozzle.

b) Pipe work reducers should have a maximum total

angle of divergence of 15 degrees.

4.6.4 Drains and Vents

Pipe pump casing drains and vent to a convenient disposal point.

Jacket piping

The stuffing boxes are jacketed for water cooling and also the bearing brackets can be jacketed. They

Page 21 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

should be provided with cooling only if required by the operating conditions

4.6.5 Pumps fitted with mechanical seals

Single seals requiring re-circulation will normally be provided with auxiliary piping from pump casing already fitted. Symbols which FLOWSERVE work on seal connections are as follows: Q - quench F - flush D - drain outlet BI - barrier fluid in BO - barrier fluid out

Single seals which require external flushing or auxiliary quench must be connected to a specific supply. Double seals require a barrier liquid compatible with the pumped liquid. With back-to-back double seals, the barrier liquid should be at a minimum pressure of 2 bar above the maximum pressure on the pump side of the inner seal. The barrier liquid pressure must not exceed limitations of the seal on the atmospheric side. For toxic service the barrier liquid supply and discharge must be in a safe area. For specific information refer to the mechanical seals manufacturer’s instructions.

4.6.6 Final checks

Check the tightness of all bolts in the suction and discharge pipework. Check also the tightness of all foundation bolts and auxiliary lines.

4.7 Final shaft alignment check

After connecting piping to the pump, rotate the shaft several times by hand to ensure there is no binding and all parts are free.

Recheck the coupling alignment, as previously described, to ensure no strain on coupling is due to pipe. If pipe strain exists, correct piping.

4.8 Electrical connections

Electrical connections must be made by a qualified Electrician in accordance with relevant local national and international regulations.

It is important to be aware of the EUROPEAN DIRECTIVE on potentially explosive areas where compliance with IEC60079-14 is an additional requirement for making electrical connections.

It is important to be aware of the EUROPEAN DIRECTIVE on electromagnetic compatibility when wiring up and installing equipment on site. Attention must be paid to ensure that the techniques used during wiring/installation do not increase electromagnetic emissions or decrease the electromagnetic immunity of the equipment, wiring or any connected devices. If in any doubt contact Flowserve for advice.

The motor must be wired up in accordance with the motor manufacturer's instructions (normally supplied within the terminal box) including any temperature, earth leakage, current and other protective devices as appropriate. The identification nameplate should be checked to ensure the power supply is appropriate.

A device to provide emergency stopping must be fitted. If not supplied pre-wired to the pump unit, the controller/starter electrical details will also be supplied within the controller/starter. For electrical details on pump sets with controllers see the separate wiring diagram.

See section 5.3, Direction of rotation

before connecting the motor to the electrical supply

4.9 Protection systems

The following protection systems are recommended particularly if the pump is installed in a potentially explosive area or is handling a hazardous liquid. If in doubt consult Flowserve. If there is any possibility of the system allowing the pump to run against a closed valve or below minimum continuous safe flow a protection device should be installed to ensure the temperature of the liquid does not rise to an unsafe level.

If there are any circumstances in which the system can allow the pump to run dry, or start up empty, a power monitor should be fitted to stop the pump or prevent it from being started. This is particularly relevant if the pump is handling a flammable liquid.

If leakage of product from the pump or its associated sealing system can cause a hazard it is recommended that an appropriate leakage detection system is installed. To prevent excessive surface temperatures at bearings it is recommended that temperature or vibration monitoring are carried out. See sections

5.7.4 and 5.7.5.

5 COMMISSIONING, START-UP, OPERATION AND SHUTDOWN

The following procedures are presented to outline the most important steps involved in pump operation. Any modification of these procedures due to particular installation peculiarities should conform to good engineering practices.

Never operate the pump with suction

valve closed. Never operate the pump unless it is filled with liquid

and vented. Never operate the pump unless a liquid source is

available. Never operate the pump with discharge valve closed

or below the minimum specified flow rate. If reduced capacity operation is required on occasion, a recirculating line should be installed according FLOWSERVE recommendations.

Where possible avoid severe thermal shocks due to sudden changes of liquid temperature. Warm-up the pump at all times before start-up if the pumped liquid is hot or subject to crystallize

Lubricate the unit prior to starting. Do not operate the unit unless coupling guards are

bolted in place. Never operate the pump above the name plate

conditions. During pump operation, keep the vent and drain

valves in closed position, to prevent any liquid from a high pressure point flowing into a low pressure point.

Do not wipe down in the vicinity of rotating parts. If unusual noise or high vibrations occur, secure the pump as soon as possible.

5.1 Pre-commissioning procedure

The following steps should be followed at initial start up and after the equipment has been overhauled: a) Prior to installing the pump, flush the suction side

of the system to remove all deposit (slag, bolts etc).

b) Ensure the pump and piping is clean. Before

putting the pump into operation, the piping should

be thoroughly back flushed to remove any foreign matter which may have accumulated during installation. Take all possible care not to contaminate your system.

c) Install suction strainer if required. (See Section

4.6.2.1).

d) Fill the bearing housings with the appropriate oil

to the correct level. Bearing must receive a small amount of oil prior to startin g to ensure adequa te lubrication at start up. (Refer to Section 5.1.1).

e) Turn pump rotor by hand or with a strap wrench

to make sure it turns smoothly.

f) Assure that correct seal piping has been installed

and has not been damaged.

Most cartridge seals are equipped

with a spacer between the gland plate and drive collar. This spacer must be removed before starting unit.

g) Prior to coupling installation, bump start motor to

check for correct rotation. If rotation is not correct refer to motor manual for appropriate connections to change rotation (Shut down all power prior to change).

h) Ensure coupling is correctly aligned and

lubricated, and pump and driver is satisfactorily doweled. (Refer to Section 4.5).

The unit must not be operated unless

coupling guard is securely and completely bolted in place. Failure to observe the warning could result in injury to operating personnel.

i) Check torque of all bolting and the plugs for

tightness.

5.1.1 Lubrication

Lubrication of bearing is by oil circulation into the bearing housing provided by oil ring, sling er or pure oil mist. A constant level oiler is normally furnished (except for pure oil mist lubrication) with the pump unless otherwise specified.

5.1.1.1 Ball Ball Lubrication

Before filling the bearing housing reservoir, flush out the housing thoroughly with safety solvent and a leading grade of flushing oil, compatible with the lubrication oil that will be used.

Page 23 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

level oiler can be adjusted by changing the height of the cross arms which support the glass reservoi r, as illustrated for TRICO oiler in section 5.1.2.

Figure 5.1

The oil circulation is ensured by slinger according to the description as follow.

Line bearing & thrust bearings side lubrication:

 The slinger splash the oil from the oil sump to

the bearing housing walls;

 The oil is collected by the oil collector and

reaches the line bearing through an hole;

 The oil returns into the oil sump once it flows

into the bearings.

Figure 5.2

Figure 5.3

5.1.1.2 Sleeve Ball Lubrication

Before filling the bearing housing reservoir, flush out the housing thoroughly with safety solvent and a leading grade of flushing oil, compatible with the lubrication oil that will be used.

The oil level must be maintained at the correct level: oil lack may cause overheating and failure of the bearings, while exceeding the correct level can result in leakage from the labyrinth seals. The constant level oiler can be adjusted by changing the height of the cross arms which support the glass reservoir, as illustrated for TRICO oiler in section 5.1.2.

The oil circulation is ensured by oil ring according to the description as follow.

Line bearing & thrust bearings side lubrication:

 The oil ring splash the oil from the oil sump to

the bearings;

 The oil returns into the oil sump once it flows

into the bearings.

Page 24 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

Figure 5.4

5.1.1.3 KTB Lubrication

The oil circulation is ensured by an high pressure system according to the description as follow.

Line bearing & thrust bearings side lubrication:

 High pressure oil pass through bearing

housing hole to the bearings;

 The oil returns into the oil sump once it flows

into the bearings.

Page 25 of 64

Figure 5.5

5.1.2 TRICO oiler setting (standard)

TRICO is used only on ball ball lubrication and sleeve ball lubrication: a) Initial fill via top of housing, using overflow plug to

establish correct level.

b) Release thumb screw and remove bottle.

Establish a measurement from the centre line of the oiler connection in bearing housing to the upper cross arm of 6 mm (0.24 in.); this can be obtained by completely screwing down the lower arm as illustrated on figure 5.6.

c) Fill bottle with recommended oil and install on

holder. Remove and fill bottle as many times as is

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

required to fill the bearing housing up to the cross arm level and no air bubbles appear in the bottle.

d) Remove bottle and ascertain that the oil level is 6

mm (0.24 in.) from the centre line of oiler connection. Adjust upper cross arm as required and lock in place with lower arm.

Figure 5.6

Never fill reservoir through the air vent

opening. The constant level oil control maintains a constant

level of oil in the reservoir. The control feeds only enough oil to maintain the required level. It operates on the liquid seal principle, feeding only when the level in the reservoir is low enough to break the liquid seal at the end of the shank, thus permitting air to enter the bottle. It will cease to feed when there is sufficient oil in the reservoir to cover the hole in the end of the shank.

5.1.3 Inspection

For ball ball and sleeve ball lubrication inspect the oil level in the bearing housing at least once a day. Inspect the condition of the oil at least weekly. Oil is always subject to gradual deterioration from use and contamination from dirt and moisture which is the cause of premature bearing wear.

Figure 5.7

Sight glass

5.1.4 Replenishment

Replenish the oil in the oiler as required for ball ball and sleeve ball. More frequent replenishment at high temperatures may be required.

5.1.5 Oil change

Frequency of oil change is dependent on pump service and environmental conditions. As a general guide, oil in the bearing housing should be changed every 4000 operating hours, after the initial change.

5.1.6 Lubrication Specification

The ideal bearing lubricant is a straight well refined, neutral mineral, preferably of the turbine type. It should not contain free acid, chlorine sulphur or more than a trace of free alkali. It is suggested th at the oil conform to the following physical characteristics.

5.1.7 Oil Mist Lubrication

5.1.7.1 Pure Oil Mist Lubrication

If the pump bearing housing is arranged for pure oil mist lubrication the following connections are provided in the bearing housing:

Ball ball lubrication:

- ¼” NPT inlet connection

- ¼” NPT vent connection

- ½” NPT drain connection

For oil lubricated pumps, fill the bearing housing with correct grade of oil to the correct level, i.e. constant level oiler bottle (standard configuration) and sight glass (when fitted on request).

(*) Note that it normally takes 2 hours for bearing temperature stabilize and the final temperature will depend on the ambient, r/min, pumpage temperature and pump size. Also some oils have a greater Viscosity Index than the minimum acceptable of 95 (e.g. Mobil DTE13M) which may extend the minimum temperature capability of the oil. Always check the grade capability where the ambient is less than -5 ºC (-23 ºF).

If a synthetic lubricant (fire resistant fluid) is to be used instead of the normal type oil for the lubrication of bearings, gears etc., the material of all gaskets and "O" rings in contact with the lubricant must be compatible with the lubricant. Normal gasket materials will usually swell and deteriorate when immersed in synthetic lubricants: also normal paints will peel from internal walls of reservoirs and bearing chambers.

In case of Pure Oil Mist lubrication the lubricant oil should be rust and oxidation inhibited and stray mist suppressed, manufactured in accordance with good commercial practice. The viscosity should be ISO VG

100. Recommended Oil Suppliers are according to the previous list.

140-160 °F

When the starting temperature is below -10°C (14°F) for long time it’s suggested to use synthetic oil. Other drivers and gearboxes, if appropriate, should be lubricated in accordance with their manuals.

In the case of product lubricated bearings

the source of product supply should

be checked against the order. There may be requirements for an external clean supply, particular supply pressure or the commencement of lubrication supply before pump start-up.

5.2.4

Lubrication schedule

5.2.4.1 Oil lubricated bearings

Normal oil change intervals are 4000 operating hours or at least every 6 months. For pumps on hot service or in severely damp or corrosive atmosphere, the oil will require changing more frequently. Lubricant and bearing temperature analysis can be useful in optimizing lubricant change intervals. The lubricating oil should be a high quality mineral oil having foam inhibitors. Synthetic oils may also be used if checks show that the rubber oil sea l s w i ll not be adversely aff ec te d. Based on the specified operating conditions and an ambient temperature of 43C (110°F) for ring-oiled or splash systems, oil sump temperature below 82C (180°F) is expected.

A continuously rising temperature, or an abrupt rise, indicates a fault.

5.3 Direction of rotation

Ensure the pump is given the same rotation as the pump direction arrow fit on bearing housing. In any case the direction of rotation must be checked with the pump disconnected. To avoid dry running the pump must either be filled with liquid or have the flexible coupling disconnected before driver is switched on.

If maintenance work has been carried out to the site's electricity supply, the direction of rotation should be re-checked as above in case the supply phasing has been altered.

Page 30 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

5.4 Guarding

Guarding is supplied fitted to the pump set. If this has been removed or disturbed ensure that all the protective guards around the pump coupling a nd exposed parts of the shaft are securely fixed.

5.5 Priming and auxiliary supplies

Ensure all electrical, hydraulic, pneumatic, sealant and lubrication systems (as applicable) are connected and operational.

Ensure the inlet pipe and pump casing are completely full of liquid before starting continuous duty operation.

Before starting or while operating the pump, the casing and suction line must be completely filled with the liquid being pumped. The rotating parts depend on this liquid for lubrication and the pump may seize if operated without liquid.

5.6 Starting the pump

a) Close discharge valve if valve is not already

closed, and then crack open to assure minimal flow. (Do not start unit with fully closed valve). On first starts care must be taken not to cause a system water hammer.

b) Prepare the driver for start up in accordance with

the driver manufacturer's instructions. c) Warm up pump (if applicable). d) Avoid severe thermal shocks to the pump as the

result of sudden liquid temperature changes. The

pump must be preheated prior to start up. Unless

otherwise specified the thermal temperature of

the casing must be within 55 °C (100 °F) of the

temperature of the liquid to be pumped at time of

start up. Due to the heavy metal sections, the

casing will lag the liquid temperature during such

changes, and severe temperature stresses and

subsequent misalignment of machined fits may

result. Preheating is accomplished by circulating

a small amount of hot fluid through the casing by

utilizing vents, drains or bypass from discharge.

Preheat pump slowly at a rate not to ex ceed 55

°C per hour (100 °F per hour). e) Prime pump and ensure suction valve is open.

Ensure flushing and/or cooling/

heating liquid supplies (if required) are turned ON before starting the pump.

Before starting or while operating

the pump, the casing and suction line must be completely filled with the liquid being pumped. The rotating parts depend on this liquid for lubrication and the pump may seize if operated without liquid.

f) Ensure pump recirculating line (if required) is

open, clear and free of obstructions.

g) Check that pump is vented by observing leakage

from casing vent (when fitted) and seal piping vent. Close vent (if fitted) when liquid is emitted.

h) Turn on cooling liquid and assure correct flow

exists (to cooler, insert gland etc.) as specified.

i) Double check pump rotation by starting unit

momentarily. The direction of input shaft

rotation is counter clockwise when facing pump shaft from coupling end. Ensure that the pump coasts down to a gradual stop.

If pump stops abruptly when d river

is shut down, investigate for pump binding. Take necessary remedial action before resuming operation.

j) Start the driver and bring it up to speed quickly. k) As soon as the pump is up to rated speed slowly

open discharge valve.

l) This will avoid abrupt changes in velocity and

prevent surging in the suction line.

m) Perform the operating checks.

5.7 Operating checks

In the interest of operator safety the unit

must not be operated above the nameplate conditions. Such operations could result in unit failure causing injury to operating personnel. Consult user instruction book for correct operation and maintenance of the pump and its supporting components.

Operation at low flows results in

pump heating the liquid. A bypass may be required to prevent vaporisation and subsequent pump damage. Refer to local FLOWSERVE branch to determine if a bypass is required. Mechanical damage may result from continuous operation at flows less than the specified minimum continuous stable flow.

Page 31 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

Immediately after start up, and frequently during running check the following:

a) Check suction and discharge pressure gauges. b) Check pressure gauges on each side of suction

strainer. c) Check for excessive leakage at seal areas. d) Check for unusual noises. e) Check oil level in bearing housing. (Refer to

Section 5).

Operation of the unit without correct

lubrication can result in overheating of the bearings, bearing failures, pump seizures and actual break-up of the equipment exposing operating personnel to physical injury.

f) Check for vibrations. g) Check for adequate flow of cooling liquids. Check for hot alignment: for services 55 °C ( 100 °F) and more above ambient, after unit has been operated a sufficient period of time to reach normal operating temperature and condition, the unit is to be shut down and a "HOT" coupling alignment check must be made (Refer to Section 4.5.4).

5.7.1 Venting the pump

Vent the pump to enable all trapped air to

escape taking due care with hot or hazardous liquids. Under normal operating conditions, after the pump

has been fully primed and vented, it should be unnecessary to re-vent the pump.

5.7.2 Pumps fitted with mechanical seal

Mechanical seals require no adjustment. Any slight initial leakage will stop when the seal is run in.

Before pumping dirty liquids it is advisable, if possible, to run in the pump mechanical seal using clean liquid to safeguard the seal face.

External flush or quench should be started before the pump is run and allowed to flow for a period after the pump has stopped.

Never run a mechanical seal dry, even for a short time.

5.7.3 Bearings

If the pumps are working in a potentially explosive atmosphere temperature or vibration monitoring at the bearings is recommended

If bearing temperatures are to be monitored it is essential that a benchmark temperature is recorded at the commissioning stage and after the bearing temperature has stabilized (see 5.2.4.1 for temperature limits). When a oil temperature sensor is provided:  set the alarm at 82 °C (180 °F) and the trip at 90

°C (194 °F) for high ambient temperature and/or

hot service When the bearing temperature sensor is provided:  set the alarm at 93 °C (180 °F) and the trip at 105

°C (200 °F) It is important, to keep a check on bearing

temperatures. After start up the temperature rise should be gradual, reaching a maximum after approximately 1.5 to 2 hours. This temperature rise should then remain constant or marginally reduce with time.

5.7.4 Normal vibration levels, alarm and trip

For guidance, pumps generally fall under a classification for rigid support machines within the International rotating machinery standards and the recommended maximum levels below are based on those standards.

Alarm and trip values for installed pumps should be based on the actual measurements (N) taken on the pump in the fully commissioned as new condition. Measuring vibration at regular intervals will then show any deterioration in pump or system operating conditions.

5.8 Normal Start Up

The starting procedure to be followed for normal start up is the same as that for initial starting with the exception that Step (i) section 5.6 "CHECK ROTATION" does not have to be repeated as long as driver systems have not been changed since last pump operation.

5.9 Stopping the pump

a) Shut down driver.

The pump should be shut

down rapidly to protect the internal wearing parts which are lubricated by the liquid be ing pumped.

If pump stops abruptly when driver is shut down, investigate for pump binding. Take necessary remedial action before restarting pump.

b) Close the pump discharge valve, while the

suction valve normally remains open.

c) Close valve in bypass line and closed whenever

possible, switch off flushing and/or cooling liquid supplies.

temperatures the pump must be drained of liquid to prevent damage to the pump. For pumping hot liquid or fluid subject to crystallize, the flush supply must be maintained on completion of pumping, to avoid seals damage.

In some installations the use of a check valve is not feasible due to the creation of pressure surges or water hammer as a result of the sudden closing of the valve under high discharge pressure. In such cases the discharge valve should be closed slowly prior to stopping the driver to eliminate the possibility of water hammer.

If pump is subjected to freezing

5.10 Hydraulic, mechanical and electrical duty

6.1 General

It is the plant operator's responsibility to ensure that all maintenance, inspection and assembly work is carried out by authorized and qualified personnel who have adequately familiarized themselves with the subject matter by studying this manual in detail. (See also section 1.6)

Oil and grease leaks may make the ground

slippery. Machine maintenance must always begin and finish by cleaning the ground and the exterior of the machine.

If platforms, stairs and guard rails are required for maintenance, they must be placed for easy access to areas where maintenance and inspection are to be carried out. The positioning of these accessories must not limit access or hinder the lifting of the part to be serviced.

When air or compressed inert gas is used in the maintenance process, the operator and anyone in the vicinity must be careful and have the appropriate protection.

Do not spray air or compressed inert gas on skin. Do not direct an air or gas jet towards other people. Never use air or compressed inert gas to clean

clothes. Before working on the pump, take measures to

prevent an uncontrolled start. Put a warning board on the starting device with the words: "Machine under repair: do not star t ".

With electric drive equipment, lock the main switch open and withdraw any fuses. Put a warning board on the fuse box or main switch with the words:

"Machine under repair: do not connect".

Before attempting any inspection or repair on the pump, the driver controls must be in the "off" position, locked and tagged to prevent injury to personnel performing service on the pump.

Before attempting to disassemble pump, pump must be isolated from system, by closing suction and discharge system valves, drained of liquid and cooled, if pump is handling hot liquid.

pipework for corrosion/erosion. b) Check internal pump components for wear. c) Change bearings

6.2.5 Re-lubrication

Lubricant and bearing temperature analysis can be useful in optimizing lubricant change intervals. In general however, the following is recommended.

6.2.5.1 Oil lubrication

Maintaining the correct oil level is very

important.

Page 34 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

If the pump is supplied with a constant level oiler the oil level will be automatically maintained and as long as oil is visible in the glass bottle there is no need to refill. If however a sight glass has been fitted then regular checks should be made to ensure the level is maintained at the centre of the glass window.

Refer to section 5.1.1 for methods of oil fill, section

5.2.1 for oil grade recommendations and 5.2.4 for the schedule and temperature limits.

6.2.6 Mechanical seals

No adjustment is possible. When leakage reaches an unacceptable level the seal will need replacement.

6.3 Spare parts

6.3.1 Ordering of spares

Flowserve keep records of all pumps that have been supplied. When ordering spares the following information should be quoted:

1) Pump serial number

2) Pump size

3) Part name (a)

4) Part number (a)

5) Number of parts required (a) Taken from the cross section dra wing stored into

the job user instruction book and only in case not available see at section 8.

The pump size and serial number are shown on the pump nameplate. To ensure continued satisfactory operation, replacement parts to the original design specification should be obtained from Flowserve. Any change to the original design specification (modification or use of a non-genuine part) will invalidate the pump’s safety certification.

6.3.2 Storage of spares

Spares should be stored in a clean dry area away from vibration. Inspection and re-treatment of metallic surfaces (if necessary) with preservative is recommended at 6 monthly intervals

Torque Values listed above are selected to achieve the correct amount of pre-stress in the threaded fastener. Maintenance personnel must ensure that threads are in good condition (free of burrs, galling, dirt, etc.) and that commercial thread lubricant NILS Wega 2 containing molybdenum disulfide is used. Torque should be periodically checked to ensure that it is at the recommended value.

6.7 Disassembly

Refer to section 1.6, Safety, before dismantling

the pump.

Before dismantling the pump for overhaul, ensure genuine Flowserve replacement parts are availab le .

Refer to sectional drawings for part

numbers and identification.

Before attempting to disassemble the pump,

the pump must be isolated from the system, by closing suction and discharge system valves, drained of liquid and cooled, if pump is handling hot liquid.

When the pump is handling “hot” liquid,

extreme care must be taken to ensure the safety of personnel when attempting to drain pump. Hot pumps must be allowed to cool before draining.

When the pump is handling “caustic” liquid,

extreme care must be taken to ensure the safety of personnel when attempting to drain pump. Protective devices of suitable protective materials must be worn when draining pump.

Before attempting any maintenance work on pumps in vacuum service, the pumps must be isolated from suction and discharge system then carefully vented to return pressure in pump casing to atmospheric pressure.

Remove the pipe plug(s) from the

top of the bearing housing(s) and check to see that oil rings are riding free on the pump shaft and are not hung up. Failure to observe this caution could result in damage to or destruction of equipment.

6.7.1 Disassembly procedure

Care must be exercised in the dismantling operation to prevent damages to internal parts of the pump. Lay out all parts in the same order in which they are removed for convenience at reassembly. Protect all machined faces against metal-to-metal contact and corrosion.

a) Switch off, lock and tag the motor circuit

breakers.

b) Switch off, isolate and tag all instrumentation and

monitoring equipment.

c) Close the pump suction valve. If discharge valve

has not already been closed this must be done prior to dismantling.

d) Remove the pump coupling guard which is bolted

to the baseplate.

e) Remove the pump coupling spacer (Refer to

coupling instructions).

Do not attempt to inspect condition

of bearings until they have been cleaned.

c) Solvent for cleaning bearings should be in a

clean container. Place bearings in solvent and let soak for a short time. Agitate the bearing around near the top of the container, giving it a turn now and then until it is clean. Rinse in a clean container of fresh solvent.

Do not spin dirty bearings. Rotate

them slowly while washing.

d) Dry thoroughly cleaned bearings. If an air hose is

used for drying, make sure it is clean dry air.

Do not allow the bearings to spin by

force of air. Hold the inner and outer rings to prevent bearing from spinning.

e) Inspect bearings immediately. If there is any

question as to the condition of a bearing do not hesitate to replace it. There are many conditions that contribute to the deterioration of the bearings. A qualified bearing representative should be consulted if there is any question of bearing condition.

f) Inspected bearings which will be reused should

be packed with new grease or dipped in clean lubricating oil, covered with clean lint free r ags or other suitable covering and placed in a clean box or carton until ready for installation.

Under no circumstances the

bearings are to be left exposed.

g) Thoroughly flush and clean the oil passages,

then coat the inner surfaces with a thin film of lubricating oil. Remove all scale and deposit in the water circulation space, if provided, by scraping and chemical treatment when necessary. Cover the bearing bodies to keep them clean until ready for installation

6.8.7.2 Sleeve Ball

Anti-friction bearings are slightly shrunk on the shaft and a pulling device must be used to remove them. The pulling jaws or fingers must be located behind the shoulder of the inner race.

Unless extreme care is used when removing an antifriction bearing, the bearing may be damaged to the extent that is no longer useable.

Always check the bearing immediately after removal for any imperfections or any play between the races. It is recommended that new bearings be used for replacement of removed bearings since very often damage caused by removal cannot be detected until the pump is put into operation.

When mounting anti-friction bearings on the pump shaft remember that the satisfactory operation of antifriction bearings requires that the inner be firmly held on the shaft so that it cannot turn on the shaft.

Heat the bearing to expand the inner race and shrink it on the shaft.

Place bearings on a shelf in a temperature controlled oven. A temperature of 80° for one half hour should be sufficient.

Care must be taken to keep the bearing clean and uncontaminated.

Check the position of the bearing on the shaft with a feeler gage to make sure it is pressing firmly against the shoulder.

6.8.7.3 KTB

Babbitted sleeve bearings The sleeve bearings supplied with the HED/HED-DS pump are of the split type and are easily removed or installed. When removed, they should be cleaned in a suitable solvent. Use rags or cloth, as waste leaves lint which might cause trouble in the bearing. A poorly cleaned bearing will score and wear out rapidly. A bearing surface is not clean until a cloth wiped over it shows no soil. Inspect all bearing parts after cleaning. Remove, with a scraper, any bruises on the babbitt faces before reassembling.

Kingsbury thrust bearing For maintenance of the Kingsbury thrust bearing refer to the manufacturer’s instructions.

6.8.8 Labyrinths or bearing isolators (if fitted)

a) The lubricant, bearings and bearing housing

seals are to be inspected for contamination and damage. If oil bath lubrication is utilized, these provide useful information on operating conditions within the bearing housing.

b) If bearing damage is not due to normal wear and

the lubricant contains adverse contaminants, the cause should be corrected before the pump is returned to service.

Page 41 of 64

HED/HED-DS USER INSTRUCTIONS ENGLISH 85392695 – 06/14

c) Labyrinth seals and bearing isolators should be

inspected for damage but are normally nonwearing parts and can be re-used.

d) Bearing seals are not totally leak free devices.

Oil from these may cause staining adjacent to the bearings.

6.9 Assembly

To assemble the pump consult the sectional drawings, see section 8, Parts list and drawin gs . Ensure threads, gasket and O-ring mating faces are clean.

6.9.1 Wear rings

The impeller is fitted with both front and rear wear rings. The impeller rings are renewable and should be replaced when badly grooved, and/or when pump performance does not meet the system requirements. Whenever it becomes necessary to replace either wear ring, both rings involved (impeller and casing cover) must be ordered and replaced as a set as they are furnished standard size only. Spare impeller wear rings are supplied with a material stock over outside diameter which has to be machined off after rings fitting on impeller. If an impeller with its wear rings is ordered as spare, it will be supplied fully machined, including wear rings outside diameter, to original dimensions. Casing Cover wear rings are always supplied fully machined. Be sure to re-establish the original running clearance between the two wear rings involved by machining the fitted impeller rings.

6.9.1.1 Impeller wear rings

a) To remove impeller wear rings, mutually remove

wear ring set screws or ground off tack weld. Rings can be machined off or grind two slots diametrically opposite across the width of the ring so it can be split apart. Use caution if ring is removed by grinding so as not to damage impeller hubs.

HAND GRI ND ER

Figure 6.3

b) Make sure ring fits on impeller are free of nicks or

burrs. Heat new ring to 107 °C (225 °F) and install on impeller. Drill and tap new holes in

IMPELLER

IMPELLER RING

impeller spaced half the circular distance from the previously used holes in the impeller. See sketch below.

Figure 6.4

Impeller wear rings when installed must

be machined to establish original diameter and running clearance. Whenever an impeller has new wear rings fitted it must be dynamically balanced before being reassembled. Refer to the Cross Sectional drawing for the requested running clearance.

The impeller wear ring bore is relieved at

one edge. Ensure that the ring is installed on the impeller so that the chamfered edge is sitting against the impeller.

6.9.1.2 Casing cover wear rings

Each wear ring is locked against rotation with a cylindrical pin. a) To remove the wear ring, press it out. If this

method does not easily effect removal of the ring, it can be split apart. First, however, drill one or

more holes in the face of the worn ring. New rings to be installed must be shrunk by freezing 20°C (-4°F) when installing in casing cover. Fit and secure with a locking pin. Replacement wear rings are furnished standard size in the bore. Check the running clearance between impeller and casing ring against the appropriate value.

6.9.2 Rotor Assembly

a) Install central shaft sleeve onto the shaft. b) Place 1st and 2 nd stage impeller key in relevant

shaft key-way.
