Introduction

1.2 Description

The CDX and IDX pumps are rugged, reliable dry vacuum pumps designed specifically for use in the chemical and pharmaceutical industries, and in industrial processing applications.

The CDX and IDX pumps are single stage pumps which use the screw principle, in which a pair of intermeshing, noncontacting rotors are held in correct phase relation by a pair of timing-gears. The gears and the double-row angular contact ball bearings are oil lubricated.

The double-ended design means that the bearings, seals and gearbox remain at atmospheric pressure, and that axial loading on the bearings is minimal.

1.3 Shaft-seals purge system

Refer to Figure 1, 2 and 3, detail C. The shaft-seals purge pipelines (24) deliver an air or nitrogen purge to the shaft- seals. This purge:

 Ensures that the shaft-seals are maintained at a positive pressure during pump operation.

 Prevents the entry of corrosive or toxic process vapours into the pump gearbox.

 Prevents contamination of t he process gases by pump oil.

 Prevents damage to the shaft-seals by debris.

Note: Accessory kits are available to provide gas ballast, inlet and exhaust purge facilities on the pump: refer

to Section 7.4.

1.4 Air bleed - IDX1300 only

CAUTION

Blockage of the air bleed intake and/or the filter element will lead to seizure of the pump.

Refer to Figure 2. The IDX1300 is fitted with a permanent atmospheric air bleed at each end of the pump.

Refer to Section 5.16 for details of how to clean/replace the filter element.

1.5 Temperature control system

Refer to Figure 1, 2 and 3. The CDX and IDX pumps have an indirect cooling system. A coolant circulation pump (driven by the vacuum pump mechanism) circulates secondary coolant, in a closed loop, through jackets around the pump body, and through oil coolers. A heat exchanger in the circuit transfers heat to the primary coolant (that is, cooling water).

The primary coolant supply passes through a filter (Figure 12, item 20).

In operation, the pump is maintained at a constant temperature by a thermostatic control-valve (TCV, 17) which controls the supply of primary coolant (cooling water) to the heat exchanger.

The heat exchanger has a pressure cap and a coolant overflow pipe (Figure 7, item 4). As the temperature of the pump body increases, and the secondary coolant expands, excess coolant may be discharged from this pipe.

Two positive displacement oil pumps located in the gearbox and the end cover circulate oil (through a filter) to cool and control the temperature of the rotors, and to lubricate the bearings and gears.

The oil circulates through oil coolers (10, 22). The oil coolers are plate heat exchangers, in which heat is transferred from the oil to the secondary coolant.

Each oil circuit is also fitted with a pressure switch (IDX) or transmitter (CDX) to protect against loss of oil supply.

Introduction

A708-01-880 Issue E

Refer to Figure 1. IDX pumps have a thermal snap-switch box (9) on the end cover which contains two thermal snap-switches and a pressure switch (32) attached to the oil supply pipe at each end:

 Connect the shut-down thermal snap-switch to a suitable control circuit to shut down the pump if it

overheats: refer to Section 3.7.

 Connect the two pressure switches to a suitable control circuit to shut the pump down if either of the oil

circuits loses pressure. This is most easily done by wiring them in series. The shut-down thermal snap switch can be wired in series with the two pressure switches to shut down the pump if any one of the three switches trip.

 Connect the warning thermal snap-switch to the control equipment to provide an indication that the pump is

too hot: refer to Section 3.7.

Refer to Figure 3. CDX pumps have a temperature sensor (9) fitted to the end cover and a pressure transmitter (32) attached to the oil supply pipe at each end. Connect these sensors to a suitable control circuit, in order to shut down the pump if it overheats or if either of the oil circuits loses pressure, refer to Section 3.6.

1.6 Drive coupling operation

The pump has a flexible drive coupling which transmits the drive from the pump motor to the pump rotors.

Refer to Figure 14. A coupling hub (10) is fitted to the pump shaft (14) and a drive hub (19) is fitted to the motor shaft (4). A flexible insert (18) fits between the two hubs.

1.7 Hazardous area and safe area versions of the pump

1.7.1 Safe area (in relation to an external atmosphere)

A safe area is one where there is no possibility of a potentially explosive atmosphere existing, therefore it is not necessary to take special precautions to avoid mechanical or electrical ignition sources.

1.7.2 Hazardous area

A hazardous area (in relation to an external atmosphere) is one where there is the possibility of a potentially explosive atmosphere existing, therefore it is necessa ry t o take spe cial prec aut ions to avoid mechanical or electrical ignition sources.

1.7.3 Pumped gases

Hazardous gases and vapours can be defined as materials that could be one or more of the following:

 To xi c

 Corrosive

 Pyrophoric

 Flammables in the flammable range

 Oxidants

 Flammables below the upper flammability limit.

Pumps that are suitable for pumping hazardous gases and vapours have a leak tightness specification of better than 10

-3

mbar l s.

Introduction

Non hazardous gases and vapours do not constitute a hazard should they leak into the external environment or should the pump develop an inward air leakage, this could include one or more of the following:

 Vapo urs

 Inert gases

 Materials below the lower flammability limit

 Non toxic materials

 Non corrosive materials.

Pumps that are suitable for pumping non hazardous gases and vapours cannot be guaranteed not to leak small amounts of gas (greater than 10

-3

mbar l s) into or out of the pump, therefore it has to be assumed that there is the

possibility for some pumped gases to be present in the external atmosphere.

Note: Where pumps suitable for non hazardous gases and vapours are used to pump inert gases they should be

located in a well ventilated area in order to avoid the possibility of asphyxiation.

The CDX pumps are suitable for Hazardous Area operation. Refer to the CDX pumping system instruction manual which will specify the technical specification and hazard classification of the system.

IDX pumps are only suitable for Safe Area operation: see Section 1.9.2.

1.8 Accessories

A number of accessories are available for the CDX and IDX pumps; use these to configure the pump for specific applications.

These accessories are listed in Section 7.4.

1.9 Normal/abnormal operation

1.9.1 Normal operation: CDX pumps

In normal operation, depending on the flame arrestors fitted and the level of systemisation, CDX pumps are safe to handle gases as follows:

External

Ex II 2 G c k IIB, IIC T3, T160, T4

Internal

Ex II 1,2 G B3, IIB T3, T4

To find out which certification has been assigned to the pumping syst em, refer to the system nameplate and specific system documentation.

If the CDX pump is part of a hazardous area system, it may be fitted with integral or external flame arrestors: refer to the CDX pumping system instruction manual.

If the CDX pump is part of an ATEX system, it may be fitted with integral or external flame arrestors: refer to the ATEX system instruction manual.

2.10 Coolant

The pump is supplied filled with Edwards coolant which is monopropylene based, and is both an antifreeze and a corrosion inhibitor. Spare Edwards coolant is available: refer to Section 7.3. A Material Safety Data Sheet for the coolant is available on request.

If using another coolant type to replenish lost coolant:

 It must prevent the formation of visible oxide sludge and scale deposits.

 It must provide frost protection down to a temperature of -14 °C (7 °F), when mixed in accordance with the

manufacturer’s recommendations.

 It must be compatible with the materials of construction of the cooling system; that is: SG iron, copper,

brass, aluminium, stainless steel, rubber (hoses) and fluoroelastomer (Viton) seals.

 It must comply with the requirements of BS 6580-1992 and BS 5117.

 It must be based on monopropylene glycol or ethylene glycol fluid.

 It must not contain amines.

The coolants shown in Table 10 may be suitable for use in the CDX and IDX pumps. All of these coolants are amine free, automotive grade, ethylene glycol antifreezes and must be d i luted to b etw e en 35% t o 50% by v o lume w i th wat er to provide the required cooling protection. However, Edwards recommends the use of Edwards coolant; Edwards cannot guarantee other types of coolant will provide the best corrosion protection for the pump.

Installation

3.6 Connect the temperature sensor (CDX pumps only)

CAUTION

Ensure to route the temperature sensor cable away from hot surfaces of the pump or other equipment. If not, the cable may be damaged.

The temperature sensor measures the oil temperature in the end cover. Connect the output of the sensor to a suitable control circuit to shut down the pump when it reaches an unsafe temperature.

Set the trip setpoint of the control circuit (that is, the temperature setpoint at which the control circuit will shut down the pump) as follows:

 For safe area and non-ATEX compliant systems, set the trip setpoint to 95 °C (203 °F) when using an air

shaft-seals purge, and 115 °C (239 °F) when using nitrogen shaft-seals purge.

 For ATEX compliant systems, the trip setpoint will be defined in the ATEX system instruction manual.

Connect the temperature sensor as follows:

1. Refer to Figure 8, detail B. Remove the top cover (3) from the sensor (5).

2. Fit a suitable cable-gland to the cable leadthrough hole (4).

3. Pass a suitable two-wire control cable through the cable-gland and into the sensor.

4. Refer to detail A. Connect the two control cable wires to terminals 1 and 2 (1, 2), as shown in the circuit schematic in detail C.

5. Tighten the cable-gland, then refit the top cover (3).

6. Connect the other ends of the two control cable wires to the control circuit.

WARNING

Connect the temperature sensor to a suitable control circuit to shut down the pump when it overheats. If not, the system will not be ATEX compliant (if applicable), pump damage can occur, and there may be a risk of explosion or fire.

WARNING

Incorporate a manual reset device in the control equipment. If not (and the temperature sensor causes the control circuit to shut down the pump), the pump will automatically switch on again when it cools down. If maintenance or fault finding has been started on the pump, there will then be a risk of fire or explosion and injury to people.

Installation

3.7 Connect the oil pressure sensors (CDX pumps only)

CAUTION

Ensure to route the pressure sensor cables away from hot surfaces of the pump or other equipment. If not, the cable may be damaged.

The pressure sensors measure the oil pressure in the supply pipes. Connect the output of the sensors to a suitable control circuit to shut down the pump when either of the sensors detects a loss of pressure.

Set the control circuit trip setpoint (that is, the pressure setpoint at which the control circuit will shut down the pump) to 0.3 barg (5 psig).

Note: Incorporate a suitable time delay in the signal in the control circuit to allow the pump to start, as initially

there is low oil pressure until the pump attains full rotational speed. The amount of delay will depend on the ramp-up time set on the VFD.

3.8 Connect the thermal snap-switches (IDX pumps only)

CAUTION

Ensure that the thermal snap-switch cable is routed away from hot surfaces of the pump or other equipment. If not, the cable may be damaged.

If required, connect the output of the warning thermal snap-switch to the control equipment to provide an indication that the pump is too hot.

Connect the output of the shut-down thermal snap-switch so that the pump is automatically switched off when it is too hot.

The thermal snap-switches will reset (that is, close again) when the pump cools down to a preset temperature (see

Section 2.8). Edwards recommends that the control equipment incorporates a manual reset device so that the pump

does not automatically switch on after it cools down.

Use the following procedure to connect to the thermal snap-switches. If connecting to the thermal snap-switches as described in this Section, the outputs from the thermal snap-switches will be normally closed and will open when the pump is too hot.

WARNING

Connect the oil pressure sensors to a suitable control circuit to shut down the pump when the oil pressure drops. If not, the system will not be ATEX compliant (if applicable), damage to the pump can result, and there may be a risk of explosion or fire.

WARNING

Connect the shut-down thermal snap-switch so that the pum p sto ps w hen t he th erm al sn ap- swit ch opens. This must be independent of the oil pressure switches so th at if the thermal sn ap switch o r either of the oil pressure switches open, the pump will be shut down. If not, a fire may result.

WARNING

Incorporate a manual reset device in the control equipment. If not (and a fault which causes the shut-down thermal snap-switch to open is not corrected), the pump will automatically switch on again when it cools down. If maintenance or fault finding has been started on the pump, there will then be a risk of injury to people.

Installation

Installation

3.9 Connect the oil pressure switches (IDX pumps only)

CAUTION

Ensure to route the thermal snap-switch cable away from hot surfaces of the pump or other equipment. If not, the cable may be damaged.

Connect the output of each oil pressure switch so that the pump is automatically switched off if the oil supply at either end fails.

Note: Incorporate a suitable time delay in the signal of the control circuit to allow the pump to start, as initially

there is low oil pressure until the pump attains full rotational speed. The amount of delay will depend on the ramp-up time set on the VFD.

Alternatively a time delay relay can be incorporated in the control circuit.

3.10 Pump motor electrical connections

3.10.1 Introduction

Make the electrical connections to the pump motor as described in the following sections.

Edwards recommends connecting the electrical supply to the pump motor through a suitable current monitor, and configuring the high current setting on the current monitor to switch off the pump motor at a suitable overload

WARNING

Connect the oil pressure switches so that the pump stops when either of the switches or the thermal snap switch opens. If not, a fire may result.

WARNING

Ensure that the electrical installation of the pump conforms to local and national safety requirements. It must be connected to a suitably fused and protected electrical supply and a suitable earth (ground) point.

WARNING

Use suitable flameproof cable glands to connect the electrical supply and control cables to the pump motor of CDX pumps. If not, the installation will not be flameproof.

WARNING

If the CDX pump is part of an ATEX system, refer to the ATEX system instruction manual before making any of the electrical connections. There may be additional electrical requirements mandated by the ATEX Directive.

WARNING

Incorporate a manual reset device in the pump electrical supply circuit. If not, and a fault condition causes a transient failure of the electrical supply, the pump will automatically switch on again when the electrical supply is restored. If maintenance or fault finding has been started on the pump, there will then be a risk of injury to people.

The pump motor can be started either Direct On-Line (DOL) or through a suitable inverter.

Refer to the motor instruction manual (supplied with the pump) for starting and overload protection requirements.

3.10.2 Connect the electrical supply to the pump motor

Connect the electrical supply to the pump motor in accordance with the requirements specified in the motor instruction manual (supplied with the pump).

3.10.3 Connect the thermistor outputs

The motor windings are fitted with thermistors which are terminated in the motor terminal box. Connect the thermistor outputs to a suitable control circuit to isolate the electrical supply from the pump motor and shut down the pump if the windings overheat.

Connect the thermistor outputs to a suitable control circuit in accordance with the requirements specified in the motor instruction manual (supplied with the pump).

3.11 Connect the pump to earth (ground)

1. Refer to Figure 1, 2 or 3, detail E. Connect one end of a suitable earth (ground) conductor to the earth (ground) stud (28).

2. Connect the other end of the conductor to a suitable earth (ground) point in the installation.

3.12 Check the direction of pump rotation

Note: The pump must be heated to at least +5 °C (41 °F) before starting or rotating the pump.

WARNING

If the CDX pump is part of an ATEX system, it must be powered by an electrical supply at the rated frequency of the pump motor, unless the system is specifically designed to operate with a variable speed drive. If this is the case, consult the ATEX system instruction manual.

WARNING

Connect the pump motor thermistor outputs to a suitable control circuit to isolate the electrical supply when the pump motor overheats. If not, the pump can be damaged, and there may be a risk of explosion or fire.

WARNING

Incorporate a manual reset device in the control equipment. If not (and a fault which causes the thermistors to shut down the pump is not corrected), the pump will automatically switch on again when the motor windings cool down. If maintenance or fault finding has started on the pump, there will then be a risk of injury to people.

WARNING

Connect the pump earth (ground) stud to a suitable earth (ground) point. If not, static electricity build-up might provide a source of ignition, and lead to explosion or fire.

2. Fit appropriate pipe fittings (see Section 2.9) to the cooling water supply and return pipes.

3. Fit the pipe fitting on the cooling water supply pipe to the water inlet connection (19), then tighten the connection.

4. Fit the pipe fitting on the cooling water return pipe to the water outlet connection (15), then tighten the connection.

3.14 Connect the shaft-seals purge gas supply

WARNING

Ensure that the pump direction of rotation is correct before operating the pump. If not, and the pump rotation is incorrect, the inlet pipeline will be pressurised and may be damaged and there will be a risk of injury to people or explosion or fire.

WARNING

Keep clear of the pump inlet when operating the pump. If not, there will be a danger of injury or death from the rotating mechanisms of the pump.

WARNING

The shaft-seals purge gas supply pressure must comply with the requirements of Section 2.6. If not, the shaft-seals purge may not operate correctly, or the purge pipelines may become overpressurised and may explode.

WARNING

If the CDX pump is part of an ATEX Category 1 system, or part of any system which handles flammable gases in their flammable range, the shaft-seals purge is safety critical, and the purge supply cannot be interrupted during operation. Refer to the ATEX system instruction manual for further details.

Installation

A708-01-880 Issue E

CAUTION

If operating a CDX pump with an oil temperature (measured on the end cover) higher than 95 °C (203 °F), use a nitrogen shaft-seals purge. If not, the shaft-seals may be damaged during operation.

Use a rigid metal (such as stainless steel) pipeline with an outside diameter of ¼ inch for the nitrogen or compressed dry air supply. If an acoustic enclosure will be fitted, ensure that the pipeline will not obstruct the enclosure.

Edwards recommends installing an automatically operated isolation valve in the gas supply pipeline configured so that:

 The shaft-seals purge gas supply is on whenever the pump is on.

 The shaft-seals purge gas supply remains on for a period of at least 30 minutes after the pump is stopped.

Refer to Figure 1, 2 or 3, detail C and use the following procedure to connect the shaft-seals purge gas supply:

1. Remove the red blanking cap from the shaft-seals purge inlet (25)

2. Connect the gas supply pipeline to the inlet.

3.15 Connect the pump inlet and outlet

Note: If the CDX pump is part of an ATEX system, refer to the ATEX system instruction manual for further

information when connecting the pump inlet and outlet.

Where there is a risk that corrosive or dangerous condensates may form inside the pumping system, Edwards recommends fitting suitable heaters to the inlet and outlet pipelines. If necessary, contact Edwards or the supplier for advice.

3.15.1 Connect the pump to the process system

Note: Flame arrestors are available as accessories: refer to Section 7.4.

When connecting the pump to the process system:

 Support process pipelines to stop the transmission of stress to pipeline joints.

 The pump must be able to be isolated from the atmosphere and process system if pumping or producing

dangerous chemicals.

 To g et t he b es t p um pi n g sp ee d , en su r e th at t he p ip e li n e which connects the process system to the pump is as

short as possible and has an internal diameter not less than the pump inlet.

WARNING

Take all necessary safety precautions when pumping toxic, flammable or explosive gases. If not, there will be a danger of injury or death to people.

WARNING

Ensure that the system can provide adequate gas ballast and/or inlet purge to dilute toxic gases to safe limits. If not, there will be a risk of emission of dangerous gases.

WARNING

If pumping flammable and explosive gases, use a CDX flame-proof pump (use a pump with integral flame arrestors, or fit external flame arrestors) and ensure that the system can provide adequate gas ballast and/or inlet purge to dilute the gases to safe levels. If not, there may be a danger of fire or explosion.

A708-01-880 Issue E

Installation

 Use a flexible connection in the pipeline from the process system to the pump to reduce vibration and stress

in the system pipelines.

Use the following procedure to connect the pump inlet to the process system. Do not allow debris to get into the pump during installation. Refer to Figure 1, 2 or 3.

1. As supplied, both IDX pumps and CDX pumps without flame arrestors have an inlet filter in the pump inlet (6):

 If installing the pump in a new process system, leave the filter in the pump inlet to prevent the entry of weld

particles or other debris into the pump. Remove the filter in Section 5.6.

 If installing the pump in an existing process system which does not contain any debris that could damage the

pump, remove the filter from the pump inlet.

2. Use suitable bolts to connect the pump inlet (6) to the process system. Use a suitable PTFE gasket to seal the connection. Edwards recommends using the gasket type specified in Section 2.9.

3.15.2 Connect the pump outlet

CAUTION

Install an outlet catchpot to prevent the drainage of condensate back into the pump. If not, condensate which drains back into the pump may damage it or cause it to seize.

Use suitable bolts to connect the pump outlet (Figure 1, 2 or 3, item 16) to the exhaust system. Use a suitable PTFE gasket to seal the connection. Edwards recommends using the gasket type specified in Section 2.9.

The exhaust pipeline system must be designed so that the pressure in the pipeline during pump operation is less than

1.15 bar absolute (1.15 x 10

Pa, 16.7 psi) for the CDX/IDX1000 and less than 1.05 bar absolute (1.05 x 105 Pa,

15.25 psi) for the IDX1300. If the pressure in the pipeline is higher than t his press ure, the p ump will oper ate at a hi gh

temperature and may trip (because of excessive electrical current consumption) or seize.

Support the exhaust pipelines to prevent the transmission of stress to the pipeline coupling-joints.

If using flexible bellows, ensure bellows which have a maximum pressure rating which is greater than the highest pressure that can be generated in the system are used.

WARNING

Connect the pump outlet to a suitable exhaust treatment plant, to prevent the discharge of dangerous gases and vapours into the surrounding atmosphere.

WARNING

Incorporate safety devices to prevent operation of the pump when the exhaust pipeline is restricted or blocked. If not, the exhaust pipeline may become over-pressurised and may burst.

WARNING

For ATEX pumps only. Install the pump outlet in such a way so that a backflow of pumped media is reliably prevented after the pump has been switched off. If an inlet valve is fitted to the inlet of the vacuum pump, it will prevent backflow of pumped media when the pump is shut down.

Installation

A708-01-880 Issue E

3.16 Leak test the system

Leak-test the system after installation and seal any leaks found. Substances which leak from the system may be dangerous to people and there may be a danger of explosion if air leaks into the system.

The leak rate of the pump is tested to be less than 1 x 10

-3

mbar l s-1 (1 x 10-1 Pa l s-1, 7.5 x 10-2 Torr l s-1) when

supplied. The required leak rate for the system will depend on the safety and process requirements.

Operation

A708-01-880 Issue E

4 Operation

4.1 Operational safety

The procedures in the following sections assume that there is a pump inlet isolation valve fitted to the pump.

WARNING

The CDX pump is suitable for handling flammable vapours from gas groups IIA, IIB3 and IIB within temperature classifications T1, T2, T3 and T4, depending on the flame arrestor configuration fitted. If in any doubt, contact Edwards for advice.

WARNING

If the CDX pump is part of an ATEX Category 1 system, or part of any system which handles flammable gases in their flammable range, the shaft-seals purge is safety critical, and ensure the purge supply cannot be interrupted during operation. Refer to the ATEX system instruction manual for further details.

WARNING

If the CDX pump is part of an ATEX system, a pump case tempe rat ure limit wi ll have be en specif ied for normal pump operation. (Refer to the ATEX syst em instru ction manual for details.) Ensure that the pump case temperature is maintained below this limit, otherwise the pump will be switched off by the ATEX control system.

WARNING

During operation, parts of the pump can become very hot. Under abnormal conditions, the temperature of the pump body can reach 115 °C (239 °F). Do not touch the pump.

WARNING

Do not operate the pump with a coupling cover removed. If so, there will be a danger of injury or death from the rotating mechanisms.

WARNING

Do not operate the pump with the pump inlet or pump outlet open to atmosphere. If so, there will be a danger of injury or death from the rotating mechanisms, from the exposure to vacuum or to toxic gases, from explosive gases, or from hot exhaust gases.

4. Check the end cover oil level: refer to Section 3.5.2.

5. Turn on the cooling water supply, shaft-seals purge gas supply and exhaust extraction system (if fitted).

6. Check that the pressure of the shaft-seals purge gas supply is correct and adjust if necessary.

7. Switch on the pump.

Note: The pump must be heated to at least +5 °C (41 °F) before starting or rotating the pump.

4.3.2 Allow the pump to warm up

CAUTION

Allow the pump to warm up and use full gas inlet purge and gas ballast (if fitted) before pumping condensable vapours. If not, the vapours may condense in the pump and corrode or damage the pump.

Leave the pump to operate (with the inlet isolation-valve closed) to allow the pump to warm up to its operating temperature.

Without inlet purge, warm-up takes approximately 90 minutes, depending on the ambient temperature.

When the pump has warmed up to its operating temperature, start process pumping.

In the first 30 seconds of pumpdown, open the inlet isolation valve slowly if there is liquid in the inlet pipeline, in order to minimize the ingress of liquid (entrained in the process gas stream) into the pump.

WARNING

During pump warm-up, coolant may drain out of the coolant overflow pipe. Take all necessary precautions if this may present a hazard.

Operation

A708-01-880 Issue E

4.3.3 Shut down the pump

CAUTION

If the pump is operating in an ambient temperature between -20 and -5 °C (-4 and 23 °F), Edwards recommends that the pump is never shut down, other than for maintenance. If doubts about this, contact Edwards for advice.

CAUTION

Purge the pump before shutting it down. If not, process vapours may condense in the pump and corrode or damage the pump.

Note: If the pump will be shut down for a long time in an environment where the temperature is close to freezing,

 Do not reuse O-rings or gaskets.

 Protect sealing-faces from damage.

 Do not touch or inhale the thermal breakdown products of fluorinated materials which may be present if the

pump has overheated to 260 °C (500 °F) and above. These breakdown products are very dangerous. The pump may have overheated if it was misused, if it malfunctioned, or if it was in a fire. Edwards Safety Data Sheets for the fluorinated materials used in the pump are available on request: contact the supplier or Edwards.

 Leak-test the system after maintenance work is complete and seal any leaks found to prevent leakage of

dangerous substances out of the system and leakage of air into the system: refer to Section 3.16.

5.2 Maintenance plan

WARNING

Obey the safety instructions in this Section and take note of appropriate precautions. Failure to observe these instructions may result in injury to people and damage to equipment.

WARNING

If the pump is certified for II C external operation, only wipe the outside of the pump with a damp cloth.

WARNING

If the CDX pump is part of an ATEX system, maintain the pump using the schedule given in Table 15 and as described in Sections 5.6, 5.7, 5.8, 5.9, 5.10, 5.11, 5.12, 5.13, 5.14, 5.15 and 5.16 of this manual, for the ATEX certification to remain valid.

If the CDX pump is part of an ATEX system, there may be additional maintenance requirements for the ATEX system: refer to the ATEX system instruction manual.

A708-01-880 Issue E

Edwards and the Edwards logo are trademarks of Edwards Limited.

Maintenance

The plan in Table 15 (page 49) details the maintenance operations that must be carried out for CDX pumps which are part of an ATEX system, and the maintenance operations Edwards recommends to maintain non-ATEX CDX pumps and IDX pumps in normal operation. Instructions for each operation are given in the section shown.

In practice, the frequency of maintenance of IDX and non-ATEX pumps is dependent on the process. In clean processes, the frequency of maintenance operations can be decreased; in harsh processes, the frequency of maintenance operations may have to increase. Adjust the maintenance plan for IDX and non-ATEX pumps according to experience.

When maintaining the pump, use Edwards maintenance and service kits. These contain all of the seals and other components necessary to complete maintenance operations successfully. The Item Numbers of these kits are given in Section 7.3.

5.3 Check the oil levels

Note: If pouring oil into the gearbox or end cover frequently, or if there is a sudden loss of a large amount of oil,

this may indicate that the pump has a fault. In these circumstances, Edwards recommends shutting down the pump as soon as possible and contact the supplier or Edwards for advice.

5.3.1 Check the gearbox oil level

Figure 1, 2 and 3 show the locations of the two gearbox oil level sight-glasses (18).

1. Refer to detail D. With the pump running, check that the pump gearbox oil level is between the MIN and MAX mark on the bezel (26) of either of the two oil level sight-glasses. If the oil level is below the MAX mark, continue at Step 2, otherwise continue at Section 5.3.2.

2. If the pump is operating, shut down the pump: (refer to Section 4) and allow the pump to cool.

3. Remove the gearbox oil filler plug and bonded seal (4): see Warning above.

4. Fit a suitable funnel or nozzle to the oil filler port, then pour oil into the pump gearbox until the oil level fills the oil level sight-glass (see detail D).

5. If the gearbox is overfilled: place a suitable container under the gearbox drain plug (Figure 10, item 3); unscrew and remove the drain plug and bonded seal and allow the oil to drain from the gearbox, then refit and tighten the drain plug and bonded seal.

6. Remove the funnel or nozzle from the oil filler port, then refit the oil filler plug and bonded seal (4).

2. Switch off the pump, and leave it for at least 15 minutes (see warning above).

3. Refer to Figure 1, 2 and 3. Remove the four bolts which secure one of the coupling covers (20) and remove the coupling cover.

4. If a pump inlet isolation-valve is in the system, close the valve. If a pump inlet isolation-valve is not in the system, disconnect the pump inlet (6) from the process system and fit a blanking-flange to the pump inlet.

5. Refer to Figure 11. Remove the two plugs (1, 2) from the cleaning solution flush ports.

6. Disconnect the pump outlet (Figure 1, 2 and 3, item 16) from the exhaust pipeline and fit a blanking-flange to the pump outlet.

7. Slowly pour a suitable cleaning solution into one of the cleaning solution flush ports (1, 2). (The other port will allow air to vent from the pump when filling it.) Wait for several minutes to allow the cleaning solution to drain into the pump.

8. Repeat Step 7 until the level of cleaning solution in the pump reaches the flush ports (see Ta b l e 3 for the capacity of the pump).

9. Leave the pump for at least one hour for the cleaning solution to fully react with the deposits in the pump.

10. Fit a steel rod or other suitable tool (not supplied) into one of the 16 mm (0.625 inch) holes in the drive hub (Figure 14, item 19), then try to turn the pump clockwise:

 If the pump cannot be turned, continue at Step 9 (to leave the pump for longer).

 If the pump can be turned, continue at Step 11.

11. Place a suitable container under the pump outlet (Figure 1, 2 and 3, item 16) and remove the blanking-flange.

12. Use the steel rod or tool to turn the pump clockwise through three or four complete revolutions. If the pump seizes, this is probably because of a hydraulic lock in the pump: wait for a few seconds for the cleaning solution to drain through the pump.

13. If necessary, repeat Steps 7 to 12 to flush the pump again.

14. Remove the blanking-flange from the pump inlet (Figure 1, 2 and 3, item 6) and reconnect the pump inlet to the process system (refer to Section 3.15.1) or open the pump inlet isolation-valve.
