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.

This symbol is used in safety instructions to remind not to rub non-metallic surfaces with a dry cloth; ensure the cloth is damp. It is used in safety instructions where non-compliance 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.

1.6.2Personnel 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.

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.

1.6.3Safety action

This is a summary of conditions and actions to prevent injury to personnel and damage to the environment and to equipment. For products

used in potentially explosive atmospheres section 1.6.4 also applies.

NEVER DO MAINTENANCE WORK WHEN THE UNIT IS CONNECTED TO POWER

GUARDS MUST NOT BE REMOVED WHILE THE PUMP IS OPERATIONAL

DRAIN THE PUMP AND ISOLATE PIPEWORK BEFORE DISMANTLING THE PUMP

The appropriate safety precautions should be taken where the pumped liquids are hazardous.

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.

APPLYING HEAT TO REMOVE IMPELLER There may be occasions when the impeller has either been shrunk fit on to the pump shaft or has become difficult to remove due to products of corrosion.

If you elect to use heat to remove the impeller, it must be applied quickly to the impeller boss. TAKE

GREAT CARE!

Before applying heat ensure any residual hazardous liquid trapped between the impeller and pump shaft is thoroughly drained out through the impeller keyway to prevent an explosion or emission of toxic vapour. This must be carried out with the shaft in the vertical position. On some pump sizes a cavity exists in the impeller bore so on occasions a significant volume of liquid may drain out.

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.

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 must be

Page 5 of 76

flowserve.com

VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 10-13

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 ºC (175 ºF) or below -5 ºC (23 ºF) in a restricted zone, or exceeds local regulations, action as above shall be taken.

HAZARDOUS LIQUIDS

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.

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 pressure, acts on the pump flange.

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

START THE PUMP WITH OUTLET VALVE PARTLY 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.)

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 pump and mechanical 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 back pressure on the pump may overload

the motor and cause cavitations. Low flow rates may cause a reduction in pump/bearing life, overheating of the pump, instability and cavitation/vibration.

1.6.4Products 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 potentially explosive atmospheres must be followed to help ensure explosion protection. For ATEX, both electrical and non-electrical equipment must meet the requirements of European Directive 94/9/EC. Always observe the regional legal Ex requirements eg Ex electrical items outside the EU may be required certified to other than ATEX eg IECEx, UL.

1.6.4.1Scope 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 ATEX 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.

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 ºC (104 ºF); 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 table only takes the ATEX temperature class into consideration. Pump design or material, as well as component design or material, may further limit the maximum working temperature of the liquid.

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 operator is responsible to ensure that the specified maximum liquid temperature is not exceeded

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

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, 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, make regular checks and remove dirt from areas around close clearances, bearing housings and motors.

1.6.4.4Preventing the buildup of explosive mixture

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, fit an appropriate dry run protection device (for example liquid detection or a power monitor).

To avoid potential hazards from fugitive emissions of vapor or gas to atmosphere the surrounding area must be well ventilated.

flowserve.com

VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 10-13

1.6.4.5Preventing sparks

To prevent a potential hazard from mechanical contact, the coupling guard must be non-sparking.

To avoid the potential hazard from random induced current generating a spark, the base plate must be properly grounded.

Avoid electrostatic charge: do not rub non-metallic surfaces with a dry cloth; ensure cloth is damp.

For ATEX applications the coupling must be selected to comply with 94/9/EC. Correct coupling alignment must be maintained.

Additional requirement for metallic pumps on non-metallic base plates

When metallic components are fitted on a nonmetallic base plate they must be individually earthed.

1.6.4.6Preventing 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, install a liquid detection device.

1.6.4.7Maintenance to avoid the hazard

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. When the contract requirement specifies these to be incorporated into User Instructions these are included here. Where performance data has been supplied separately to the purchaser these should be obtained and retained with these User Instructions if required.

1.9 Noise Level

Attention must be given to the exposure of personnel to the noise, and local legislation will define when guidance to personnel on noise limitation is required, and when noise exposure reduction is mandatory. This is typically 80 to 85 dBA.

Page 8 of 76

flowserve.com

VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 10-13

The usual approach is to control the exposure time to the noise or to enclose the 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 attention is drawn to the following table to give an indication of equipment noise level so that you can take the appropriate action in your plant.

Pump noise level is dependent on a number of operational factors, flow rate, pipework design and acoustic characteristics of the building, and so the values given are subject to a 3 dBA tolerance and cannot be guaranteed.

Similarly the motor noise assumed in the “pump and motor” noise is that typically expected from standard and high efficiency motors when on load directly driving the pump. Note that a motor driven by an inverter may show an increased noise at some speeds.

If a pump unit only has been purchased for fitting with your own driver then the “pump only” noise levels in the table should be combined with the level for the driver obtained from the supplier. Consult Flowserve or a noise specialist if assistance is required in combining the values.

It is recommended that where exposure approaches the prescribed limit, then site noise measurements should be made.

The values are in sound pressure level LpA at 1 m (3.3 ft) from the machine, for “free field conditions over a reflecting plane”.

For estimating sound power level LWA (re 1pW) then add 17 dBA to the sound pressure value.

The noise levels shown in table 1.9.1 are extracted from typical motor manufacturer’s data/catalogue to provide the average expected motor noise values at no load for reference only and are not guaranteed. The values could vary depending upon the test and surrounding conditions. The combined noise level of the pump and the motor could exceed the values shown. It is to be noted that adding motors with similar noise levels increases the total noise level. Therefore, the dB correction to the values listed above is required to obtain the combined noise levels of motor and the pump. Actual on-site noise measurement by experts is recommended and safety measures are to be taken accordingly.

VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 10-13

A shaft sealing arrangement is located in the discharge head to seal the shaft at its exit from the liquid chamber.

The shaft seal will usually be either a mechanical seal assembly or stuffing box with an open lineshaft or a tube-packing box with an enclosed lineshaft.

3.3.3Column assembly

The column assembly consists of column pipe, which connects the bowl assembly to the discharge head and carries the pumped fluid to the discharge head. Houses and supports the shaft and may contain bearings. Typical column assemblies are:

a) flanged column assembly

b) threaded column assembly: from 100 mm~355 mm (4~14 in.) sizes only.

The column supports shaft assembly, that is either

a)Open lineshaft construction utilizing the fluid being pumped to lubricate the lineshaft bearings.

Or

b)Enclosed lineshaft construction has an enclosing tube around the lineshaft and utilizes oil or other fluid to lubricate the lineshaft bearings.

The shafts are threaded or key coupled with thrust stud design or clamp ring design.

See sectional drawings supplied with the pump for exact column assembly details as per the order. The size and configuration vary depending upon the specific order requirements and application criteria.

3.3.4Bowl assemblies

The bowl assembly consists of impellers rigidly mounted on the pump shaft coupled to an electric motor. Impellers are cast wheels with multiple diffuser vanes and are generally coated to meet the hydraulic requirements. See section 8.0 for cross sectional and part details.

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

When equipment has been in storage for greater than 6 months, a complete inspection should be conducted in accordance with section 2.4.3. The pump should be located to allow room for access, ventilation, maintenance and inspection with ample headroom for lifting and should be as close as practicable to the supply of liquid to be pumped. Refer to the general arrangement drawing for the pump set.

4.1.1Inspection prior to installation

Six months prior to the scheduled installation date, a Flowserve Pump Division representative is to be employed to conduct an inspection of the equipment and the facility. If any deterioration of equipment is noticed, the Flowserve Pump Division representative may require a partial or complete dismantling of the equipment including restoration and replacement of some components.

4.2 Preparation

The pump should be located to allow room for access, ventilation, maintenance and inspection with ample headroom for lifting and should be as close as practicable to the supply of liquid to be pumped.

Refer to the general arrangement drawing for the pump dimensions and details.

4.2.1General installation check-list

The following checks should be made before starting actual installation.

a)Make sure that motor nameplate ratings and the power supply system match correctly.

b)Check the sump depth and pump length matchup.

c)Check the liquid level in the sump.

d)Check the installation equipment to be sure that it will safely handle the pump weight and size.

e)Check all pump connections (bolts, nuts etc) for any shipping and handling related problems.

Always support shafting in at least three places when lifting or installing. No installation should be attempted without adequate equipment necessary for a successful installation.

On hollow shaft drivers, check the clutch size against the shaft size, which must go through the clutch

On solid shaft drivers, check the motor shaft size against the coupling bore size

Apply thread lubricant sparingly to male shaft threads only at the time of making up shaft connection. Excess lubricant should be avoided.

Always check motor rotation before connecting driver to pump. Reserve rotation due to improper motor direction can cause extensive damage to the pump.

4.3 Foundation/Anchor Bolts

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 vibration limitations. Non-compliance with the

Page 21 of 76

flowserve.com

VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 10-13

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 must consist of material that will afford rigid support to the discharge head and will absorb expected stresses that may be encountered in service.

Concrete foundations should have anchor bolts installed in sleeves that allow alignment and have holes in the mounting plate as illustrated in the detail below. Sleeve should be filled with non-bonding moldable material after sleeve is set in place.

When a suction barrel is supplied as in the case of the type "TF" discharge head, the suction vessel must provide permanent, rigid support for the pump and motor.

All foundation / anchor bolt recommendations should be verified by prevailing industry standards.

Some wet pit pumps are installed directly by using the flange that comes as an integral part of the discharge head. The pump is lowered into the pit and aligned with the anchor bolts [372].

The mounting flange is shimmed to achieve required level by using a precision machinist’s level. The pump is to be leveled to within 0.16 mm/m

(0.002 in./ft). The data to be recorded for future reference. Anchor bolt nuts [373] are tightened sufficient enough to hold down the pump in place.

Grout is poured and allowed to set for at least 72~80 hours (cure as required) before any further work is done on the pump.

If leveling nuts are used to level the base, they must be backed off as far as possible prior to grouting.

Always shim near foundation bolts and then back off the leveling nuts. Now tighten the foundation bolts. If done otherwise there is a risk of significantly lowering the structural natural frequency that could result in separation of the base from the grout.

Directly mounted pumps are not user friendly for service. Re-installation of these pumps requires re-leveling and re-grouting.

4.3.2Leveling of pumps mounted on a

soleplate and the soleplate is grouted

Some pumps are mounted on a separate plate known as soleplate [23]. In such cases, the level shall be set with a master level or a precision machinist’s level. The mounting surface needs to be leveled to within 0.16 mm/m (0.002 in./ft).

The level should not exceed 0.125 mm (0.005 in.) elevation difference taken on any two points on the individual soleplate. Accurate shimming and grouting of the soleplate is very important. Record the leveling data for future reference. Grout the soleplate and allow to set at least 72~80 hours (cure as required) before the pump is lowered into the pit. Align the discharge head boltholes with the anchor bolts [372].

Check and adjust the pump level to within

0.16 mm/m (0.002 in./ft) with respect to the soleplate and torque the nuts [373] to the required level.

(also referred as “Can” VTPs)

The suction barrel [315] is first lowered into the pit and aligned with the anchor bolts [372]. The suction barrel flange is leveled by using a master level or a precision machinist’s level. Levels should be taken on the equipment mounting surfaces. The suction barrel flange mounting surface needs to be leveled to within

0.16 mm/m (0.002 in./ft) using shims and grouted.

Allow the grout to set for at least 72~80 hours before the pump is installed. Check the barrel mounting surface level after the grout is set and then proceed with the pump installation. Lower the pump assembly into the pit and align the discharge head flange bolt holes to the anchor bolts [372].

Check and adjust the pump level with respect to the barrel flange to within 0.16 mm/m (0.002 in./ft) and final torque the nuts [373]. The leveling data to be recorded for future reference.

Where applicable, grout in the foundation bolts. After adding pipe work connections and re-checking the coupling alignment, the mounting plate/soleplate should then be grouted in accordance with good engineering practice. If in any doubt, please contact Flowserve service center for advice.

Grouting provides solid contact between the pump unit and foundation that prevents lateral movement of running equipment and dampens resonant vibrations. Care should be taken to ensure maximum surface contact with grout between the pump base, sole plate, suction can and foundation (no voids).

Foundation bolts should only be fully tightened after the grout has been cured.
