DANGER

⚠ WARNING

BEFORE opening any liquid chamber (pumping chamber, reservoir, relief valve adjusting cap fitting, etc.) be sure that:

INSTALL pressure gauges/sensors next to the pump suction and discharge connections to monitor pressures.

• Any pressure in the chamber has been completely vented through the suction or discharge lines or other appropriate openings or connections.

© Viking Pump, Inc.

• The pump drive system (motor, turbine, engine, etc.) has been “locked out” or otherwise been made non-operational, so that it cannot be started while work is being done on the pump.

• You know what material the pump has been handling, have obtained a material safety data sheet (MSDS) for the material, and understand and follow all precautions appropriate for the safe handling of the material.

⚠ WARNING

USE extreme caution when lifting the pump. Suitable lifting devices should be used when appropriate. Lifting eyes installed on the pump must be used only to lift the pump, not the pump with drive and/or base plate. If the pump is mounted on a base plate, the base plate must be used for all lifting purposes. If slings are used for lifting, they must be safely and securely attached. For weight of the pump alone (which does not include the drive and/or base plate) refer to the Viking

Pump ® product catalog.

DANGER

DO NOT place fingers into the pumping chamber, or its connection ports, or into any part of the drive train if there is any possibility of the pump shaft being rotated.

AVOID contact with hot areas of the pump and/or drive.

Certain operating conditions, temperature control devices

(jackets, heat-tracing, etc.), improper installation, improper operation, and improper maintenance can all cause high temperatures on the pump and/or drive.

⚠ WARNING

© Viking Pump, Inc.

⚠ WARNING

BEFORE operating the pump, be sure that:

• It is clean and free from debris.

• All valves in the suction and discharge pipelines are fully opened.

• All piping connected to the pump is fully supported and correctly aligned with the pump.

THE PUMP must be provided with pressure protection. This may be provided through a relief valve mounted directly on the pump, an in-line pressure relief valve, a torque limiting device, or a rupture disk. If pump rotation may be reversed during operation, pressure protection must be provided on both sides of pump. Relief valve adjusting screw caps must always point towards suction side of the pump. If pump rotation is reversed, position of the relief valve must be changed. Pressure relief valves cannot be used to control pump flow or regulate discharge pressure. For additional information, refer to Appendix , General Installation Notes ,

© Viking Pump, Inc.

®

⚠ WARNING

• Pump rotation is correct for the desired direction of flow.

© Viking Pump, Inc.

THE PUMP must be installed in a manner that allows safe access for routine maintenance and for inspection during operation to check for leakage and monitor pump operation.

INTRODUCTION

The illustrations used in this manual are for identification purposes only and cannot be used for ordering parts.

Obtain a parts list from your Viking Pump ® representative.

Always give a complete name of part, part number and material with the model number and serial number of pump when ordering repair parts. The unmounted pump or pump unit model number and serial number are on the nameplate.

This manual only applies to the pump models specified in the

"Model Number Chart" on page 1 . Pump specifications and recommendations are listed in the Catalog Sections, which

SPECIAL INFORMATION

PRESSURE RELIEF VALVES

1. Viking pumps are positive displacement pumps and must be provided with some sort of pressure protection. This may be a relief valve mounted directly on the pump, an inline pressure relief valve, a torque limiting device or a rupture disk.

© Viking Pump, Inc.

include a jacketed relief valve or return to tank relief valve.

3. If pump rotation is reversed during operation, pressure protection must be provided on both sides of pump.

4. Relief valve adjusting screw cap must always point towards suction side of pump, see

"Figure 5" on page

15

. If pump rotation is reversed, remove pressure relief valve and turn end for end.

5. Pressure relief valves cannot be used to control pump flow or regulate discharge pressure.

ROTATION

Viking pumps can operate equally well in a clockwise or counter-clockwise rotation; however, some constructions may require modifications. Consult your Viking Pump ® representative if unsure. Shaft rotation determines which port is suction and which is discharge. Suction port is where pumping elements (gear teeth) come out of mesh.

For additional information on pressure relief valves, Refer to

representative for

MECHANICAL SEALS

Extra care should be taken in repair of pumps with mechanical seals. Be sure to read and follow all special instructions supplied with your pump.

Relief valve adjusting screw cap must always point towards suction side of pump. If pump rotation is reversed, remove pressure relief valve and turn end for end.

CIRCULATION LINES

This equipment (not utilized on all pumps) must be connected properly. Packed pumps typically have a flush line from packing chamber to discharge port. Mechanical seal pumps typically have a suckback line from seal chamber to suction port. If pump rotation is reversed, be sure circulation

© Viking Pump, Inc.

If pump is handling heated product, be sure circulation line is insulated to assure continued flow.

JACKETED PORTS

Jackets are utilized to heat (or cool) the pump and liquid in the pump prior to startup. Not all pumps have ports for jacketing.

Jacketing port locations vary by model.

MAINTENANCE

These pumps are designed for long, trouble-free service life

service life.

LUBRICATION

External lubrication must be applied slowly with a hand gun to all lubrication fittings every 500 hours of operation with multi-purpose grease, NLGI # 2. Contact your Viking

Pump ® representative with specific lubrication questions.

Engineering Service Bulletin ESB-515 is located in the

Appendix for standard grease thickener types used by Viking to check compatibility. Applications involving very high or low temperatures will require other types of lubrication. O-Pro™

DANGER !

Before opening any Viking pump liquid chamber

(pumping chamber, reservoir, relief valve adjusting cap fitting, etc.) be sure:

© Viking Pump, Inc.

lines, or other appropriate openings or connections.

2. That the driving means (motor, turbine, engine, etc.) has been “locked out” or made non-operational, so that it cannot be started while work is being done on pump.

3. That you know what liquid the pump has been handling and the precautions necessary to safely handle the liquid. Obtain a material safety data sheet (MSDS) for the liquid to be sure these precautions are understood.

Failure to follow above listed precautionary measures may result in serious injury or death.

ASSEMBLY

Reverse procedures outlined under Disassembly. If valve is removed for repairs be sure to replace in same position.

Relief valve adjusting screw cap must always point towards suction side of pump. If pump rotation is reversed, remove relief valve and turn end for end.

If a new spring is installed or if pressure setting of pressure relief valve is to be changed from that which the factory has set, the following instructions must be carefully followed.

1. Carefully remove valve cap which covers adjusting screw.

Loosen locknut which locks adjusting screw, so pressure setting will not change during operation of pump.

2. Install a pressure gauge in the discharge line for adjusting the relief valve setting during operation.

3. Turn the adjusting screw CW (in) to increase the

© Viking Pump, Inc.

representative for Engineering Standard ES-37.

®

4. Close the discharge line at a point beyond the pressure gauge. Limit the amount of time the pump is operated at this condition. The temperature inside the pump will rise rapidly. The pressure gauge will show maximum pressure that valve will allow while pump is in operation.

5. Once the relief valve pressure is set, tighten locknut and replace the cap gasket and valve cap.

IMPORTANT ORDERING INFORMATION

In ordering parts for pressure relief valve, always give

© Viking Pump, Inc.

be sure to give pressure setting desired.

© Viking Pump, Inc.

Mark valve and head before disassembly to ensure proper reassembly.

1. Remove valve cap.

2. Measure and record length of extension of adjusting screw. Refer to “A” on

"Figure 21" on page 15 .

3. Loosen locknut and back out adjusting screw until spring pressure is released.

Before installation is started, a few items of a general nature should be considered.

© Viking Pump, Inc.

© Viking Pump, Inc.

1. Location - always locate the pump as close as possible to the supply of liquid to be pumped. Locate it below the liquid supply if at all practical. Viking pumps are self priming but the better the suction conditions the better the performance.

2. Accessibility - the pump should be located where it is accessible for inspection, maintenance, and repair. For large pumps, allow room to remove the rotor and shaft without removing the pump from the base.

3. Port Arrangement - since the pumps have different port arrangements depending on the model, port location should be checked before starting the installation. The ports may be upright, opposite or at right angles to each other, see Figure A1 . The right angle ports are normally right-hand, see Figure A2 ; some models are available with left-hand arrangements; still other models are available with the right angle ports located in any one of eight positions including right-hand and left-hand.

“A” on Figure A3 , liquid is drawn into the suction port.

Then at point “B” the gears come into mesh, and the liquid is forced out the discharge port. Reversing the rotation reverses the flow through the pump. When determining shaft rotation, always look from the shaft end of the pump.

Unless otherwise specified, rotation is assumed to be clockwise (CW), which makes the suction port on the right side of the pump. The idler pin, which is offset in the pump head, should be properly positioned toward and an equal distance between the port connections. See Figure A3 for correct idler pin location in relation to pump ports.

Suction

Internal type relief valves mounted on Viking pumps should always have the cap or bonnet pointed toward the suction side of the pump. Return-to-tank type relief valves should always be mounted on the discharge side of the pump. If pump rotation is reversed, change the relief valve. Turn the internal type end for end; move the

CAUTION !

Viking pumps can be furnished with either an internal pressure relief valve - one which directs the flow from the

to the supply tank. See Figure A5-A and Figure A5-B .

An inline relief valve mounted in the discharge piping also directs the flow back to the supply tank. This type of valve should be mounted close to the pump so that the pressure drop through the piping between the pump and the valve is at a minimum. Be sure there are no shutoff valves between the pump and relief valve. Piping from a returnto-tank or an in-line valve to the supply tank should also be as short and as large as possible.

to fill a tank, and then by use of a reversing switch or other means of changing the rotation to permit the same pump to circulate the liquid through a heater or to load out, then pressure protection must be provided on both sides of the pump for both rotations. This may be a combination of relief valves, torque limiting devices or rupture disks.

NOTE: On some models, the relief valve is mounted on the pump casing instead of the pump head.

valve, sensing only those pressures on each side of the poppet. It should not be used as a pressure or flow control device. It is intended strictly as a relief valve.

The pressure at which either the return-to-tank or internal relief valve bypasses can be changed by turning the adjusting screw. Do not back the adjusting screw all the way out. Stop when spring tension is off the screw (the screw starts to turn easily). For details on maintenance of the relief valve, refer to the Technical Service Manual covering your model series.

6. Motor - follow local electrical codes when hooking up

some form of pressure protection, e.g. torque limiting devices or rupture disks.

5. Pressure Protection - Viking pumps are positive displacement pumps. This means that when the pump is rotated, liquid will be delivered to the discharge side of the pump. If there is no place for this liquid to go, i.e. the discharge line is blocked or closed, pressure can build up until the motor stalls, the drive equipment fails, a pump part breaks or ruptures, or the piping bursts. Because of this, some form of pressure protection must be used with

© Viking Pump, Inc.

torque limiting device or a rupture disk.

Every pump should have a solid foundation. It may be any structure sufficiently strong to hold the pump rigid and to absorb any strain or shock that may be encountered.

A certified print of the pumping unit should be used in preparing the foundation. If a separate foundation is provided, make it at least four inches wider and longer than the base of the unit.

When the unit is placed on the foundation, it should be leveled

COMPONENT & UNIT LIFTING

FEATURES

The pressure relief valve mounted on most Viking pumps and most in-line valves are of the spring-loaded poppet design. See Figure A4 . The spring (a) holds poppet

(b) against the seat in the valve body (c) with a given force determined by the spring size and by how tightly it is compressed by the adjusting screw (d). The pump discharge pressure pushes against the underside of the poppet at point (e). When the force exerted by the liquid under the poppet exceeds that exerted by the spring, the poppet lifts and liquid starts to flow through the valve.

Removable lifting features, such as threaded eye bolts and hoist rings, installed in components (pumps, reducers, motors, etc.) and baseplates should be left on the components.

These features are used to safely lift and move the individual components. Following are general guidelines for lifting Viking

Pump ® units.

ALIGNMENT

CHECK ALIGNMENT AFTER MOUNTING

For detailed coupling alignment procedures see coupling manufacturers’ recommendations.

The pump, drive, and motor were properly aligned at the time they were assembled. During shipping and mounting the alignment is often disturbed. BE SURE TO RECHECK

ALIGNMENT AFTER THE PUMP UNIT IS INSTALLED!

1. Check pump ports to be sure they are square and in the proper position; shim or move the pump as required. Do

© Viking Pump, Inc.

2. If the pump is driven by a flexible coupling(s) either directly connected to the motor or through a reducer, remove any coupling guards or covers and check alignment of the coupling halves. At a minimum, a straightedge (such as a piece of key stock) across the coupling must rest evenly on both rims at the top, bottom, and sides.

See Figure A10-A .

3. If the pump is driven by V-belts, check the alignment by using a long straightedge or tightly drawn string across the face of the sheaves. See Figure A10-B .

4. Make a final check on alignment after piping is hooked up.

© Viking Pump, Inc.

Piping section.

Figure A11 and Figure A12 show typical direct drive and gear reducer drive units.

5. For high temperature applications (those above 300°F) allow the pump to reach operating temperature, then recheck alignment.

FIGURE A11: DIRECT DRIVE

© Viking Pump, Inc.

FIGURE A12: REDUCER DRIVE

© Viking Pump, Inc.

PIPING

The cause of many pumping problems can be traced to suction piping. It should always be as large and short as practical. For help in selecting the proper size suction and discharge piping, refer to Viking General Catalog Section 510 .

1. Never use piping smaller than the pump port connections.

2. Be sure the inside of the pipe is clean before hooking it to the pump.

3. FOOT VALVE - When pumping a light liquid with a suction lift, a foot valve at the end of the suction piping or a check valve in the first horizontal run will hold the liquid in the line and make it easier for the pump to prime. Be sure the foot or check valve is big enough so that it doesn’t cause excessive line loss.

4. When approaching an obstacle in the suction or discharge

© Viking Pump, Inc.

Figure A13 .

5. Where practical, slope the piping so no air or liquid pockets will be formed. Air pockets in the suction line make it hard for the pump to prime.

6. For a suction line with a long horizontal run, keep the horizontal portion below the liquid level if possible. This keeps the pipe full of liquid and reduces the amount of air the pump must evacuate at startup. This is most helpful when there is no foot valve. See Figure A14 .

7. When piping a hot or cold system (liquid being handled is at a temperature different from the air surrounding the pump),

© Viking Pump, Inc.

not mean unsupported) runs should be used so the pump casing is not distorted.

8. STRAINER - It is always good practice to consider a strainer on the suction side of a positive displacement pump. The strainer will keep foreign objects from going into the pump. Without a strainer objects can lock the pump, and damage the internals and drive. The strainer basket mesh or perforation size should be big enough so that it does not cause excessive pressure drop, but it should be fine enough to protect the pump. When in doubt as to the proper size, check with the manufacturer, giving

© Viking Pump, Inc.

operates continuously, a bypass should be built around the strainer, or two strainers should be put in parallel with proper valving so they can be isolated for cleaning. Use of a strainer is particularly important at start up to help clean the system of weld beads, pipe scale, and other foreign objects. For additional information, refer to TSM 640 .

9. If the pump is not equipped with a relief valve, consideration should be given to mounting one in the discharge line. Refer to discussion on pressure protection under item 5 in General Installation Notes section.

10. The pump should not be used to support the piping.

© Viking Pump, Inc.

11. When fastening the piping to the pump it should not be necessary to impose any strain on the pump casing.

cause distortion, possible misalignment, and probable rapid wear of the pump. Do not use the pump to correct errors in piping layout or assembly.

START UP

© Viking Pump, Inc.

Before starting the pump, check the following:

12. All joints of the piping system should be tight; pipe sealer will help assure leak-free threaded joints. Leaks in the suction line permitting air to be drawn in may cause a noisy pump or a reduction in capacity. It is not recommended to use PTFE tape on NPT ports as a pipe sealer. This action can result in cracks in the pump.

1. Are there vacuum and pressure gauges on or near the pump? These gauges are the quickest and most accurate

© Viking Pump, Inc.

2. Check alignment - See suggestions in the Alignment section of this manual.

3. Check piping to be sure there is no strain on the pump casing.

13. ALIGNMENT - Check the alignment of the drive after the piping is hooked up. As a final check on pump alignment, remove the head of the pump and with a feeler gauge determine if there is clearance all the way around between the rotor and casing. Because of manufacturing tolerances, bushing clearances, etc., the rotor may not be centered in the casing, but it should not drag; dragging would indicate unit misalignment or casing distortion from piping strain. Making this check is most desirable on installations involving Q, M and N size general purpose pumps.

4. Rotate the pump shaft by hand to be sure it turns freely.

MAKE SURE THE PUMP DRIVER IS LOCKED OUT OR

CANNOT BE ENERGIZED BEFORE DOING THIS.

5. Jog motor to be sure it is turning in the right direction; refer to discussion on pump rotation under item 4 in General

Installation Notes section.

© Viking Pump, Inc.

© Viking Pump, Inc.

14. The auxiliary piping hooked to jackets, glands, etc. for heating, cooling, quenching, or for other purposes should receive the same attention as the piping handling the pumped liquid.

7. Check suction piping to be sure: a. It is all connected and tight

General

c. There is a place for the liquid to go

© Viking Pump, Inc.

The rise in temperature causes the liquid to expand; if there is no provision for pressure relief in the closed off section, there is a chance that the pump or piping will rupture.

9. Lubricate any grease fitting on the pump using a #2 NLGI grease. Check any gear reducer, motor, coupling, etc. for instructions and lubricate as recommended by the manufacturer. See Engineering Service Bulletin

ESB-515 at the end of the Appendix for Viking standard grease types to check compatibility.

10. For packed pumps, loosen packing gland nuts so gland can be moved slightly by hand. Adjust gland to reduce leakage only after pump has run long enough to reach constant temperature. Packing should weep a little to keep it cool and lubricated.

13. Check the pump to be sure it is heated to operating temperature (if jacketed or heat traced).

If the pump begins to deliver liquid within 60 seconds, it can continue to be operated. If liquid is not leaving the discharge port, stop the pump. Running the pump longer than one minute without liquid inside it can damage the pump.

Review the steps just outlined, consider what the suction and discharge gauges indicate, and see Troubleshooting

If the pump still does not deliver flow, the cause may be one or more of the following:

1. Suction line air leaks. Vacuum gauge reading should help determine if this is the problem.

2. End of suction pipe not submerged deep enough in liquid.

3. Suction lift is too great or the suction piping is too small.

4. Liquid is vaporizing in the suction line before it gets to the pump.

If after consideration of these points it still does not pump, review again all points under START UP . Read through

TROUBLESHOOTING

A Viking pump that is properly installed and maintained will give long and satisfactory performance.

NOTE: Before making any pump adjustment or opening the pump liquid chamber in any manner, make sure that:

1. Any pressure in the pumping chamber has been vented through the suction or discharge lines or other openings provided for this purpose.

2. The driver has been “locked out” so that it cannot

3. The pump has been allowed to cool down to the point where there is no chance of anyone being burned.

If trouble does develop, one of the first steps toward finding the difficulty is to install a vacuum gauge in the suction port and a pressure gauge in the discharge port . Readings on these gauges often will give a clue as to where to start looking for the trouble.

VACUUM GAUGE - SUCTION PORT

1. High reading would indicate: b. Liquid is too viscous to flow through the piping.

c. Lift is too high.

d. Line is too small.

2. Low reading would indicate: a. Air leak in suction line.

b. End of pipe is not in liquid.

c. Pump is worn.

d. Pump is dry - should be primed.

a. Liquid is vaporizing.

b. Liquid is coming to pump in slugs, possibly an air leak, insufficient liquid above the end of the suction pipe.

c. Vibrating from cavitation, misalignment, or damaged parts.

PRESSURE GAUGE - DISCHARGE PORT

1. High reading would indicate: a. High viscosity, small diameter discharge line or long discharge line.

b. Gate valve is partially closed.

d. Vertical head did not consider a high specific gravity liquid.

e. Line is partially plugged from build up on inside of pipe.

f. Liquid in the pipe is not up to temperature.

g. Liquid in the pipe has undergone a chemical reaction and has solidified.

h. Relief valve is set too high.

2. Low reading would indicate: a. Relief valve is set too low.

b. Relief valve poppet is not seating properly.

d. Too much extra clearance.

e. Pump is worn.

3. Fluttering, jumping, or erratic reading: a. Cavitation.

b. Liquid is coming to the pump in slugs.

c. Air leak is in the suction line.

d. Vibrating from misalignment or mechanical problems.

Some of the following may also help pinpoint the problem:

1. Pump has lost its prime due to air leak, low level in tank, foot valve stuck.

2. Suction lift is too high.

3. Rotating in wrong direction.

4. Motor does not come up to speed.

5. Suction and discharge valves not open.

6. Strainer is clogged.

7. Bypass valve open, relief valve set too low, relief valve poppet stuck open.

8.

9. Any changes in the liquid system or operation that would help explain the trouble, e.g. new source of supply, added more lines, inexperienced operators, etc.

10. Too much end clearance.

11. Head position is incorrect. See Figure A3 .

12. Temperature changes either in the liquid or environment.

13. Mag Drive pumps ONLY: The magnetic coupling is decoupling. Changes in application (temperature, pressure, viscosity, etc.) may require torque beyond coupling capabilities.

1. Supply tank is empty.

2. Liquid is vaporizing in the suction line.

3. Air leaks or air pockets in the suction line; leaking air through packing or mechanical seal.

PREVENTATIVE MAINTENANCE DO’S & DON’TS

Performing a few preventative maintenance procedures will extend the life of your pump and reduce the overall cost of ownership.

Do’s and Don’ts for installation, operation, and maintenance of Viking pumps to assure safe, long, trouble-free operation.

A. Lubrication - Grease all grease fittings after every 500 hours of operation. If service is severe, grease more often.

Do it gently with a hand gun until the grease exiting the lip seal or relief plug is similar in consistency and color to the new grease.

INSTALLATION

© Viking Pump, Inc.

2. DO leave working space around the pumping unit.

3. DO use large, short, and straight suction piping.

4. DO install a strainer in the suction line.

Use a NLGI #2 grease for normal applications. See

© Viking Pump, Inc.

at the end of the Appendix applications, use appropriate grease.

for Viking standard grease types to check compatibility. For hot or cold

O-Pro™ seals should also be greased every 500 hours of operation with a lubricating fluid compatible with the process fluid.

5. DO double check alignment after the unit is mounted and piping is hooked up.

6. DO provide a pressure relief valve for the discharge side of the pump.

7. DO cut out the center of gaskets used as port covers on flanged port pumps.

B. Packing Adjustment - Occasional packing adjustment may be required to keep leakage to a slight weep. If impossible to reduce leakage by gentle tightening, replace packing or use different type. Refer to Technical Service

Manual on particular model series for details on repacking.

8. DO record pump model number and serial number and file

© Viking Pump, Inc.

OPERATION

1. DON’T run pump at speeds faster than shown in the catalog for your model.

C. End Clearance Adjustment - After long service, the running clearance between the end of the rotor teeth

© Viking Pump, Inc.

end clearance will normally improve pump performance.

Refer to TSM on particular model series for procedure on adjusting end clearance for pump involved.

2. DON’T require pump to develop pressures higher than those shown in the catalog for your model.

3. DON’T operate pumps at temperatures above or below limits shown in the catalog for your pump.

4. DON’T operate pumps without all guards being in place.

D. Examine Internal Parts - Periodically remove the head, examine idler and bushing and head and pin for wear.

Replacing a relatively inexpensive idler bushing and idler pin after only moderate wear will eliminate the need to replace more expensive parts at a later date. Refer to

TSM on particular model series for procedure in removing head of the pump.

Be sure idler does not slide off the idler pin as the head is removed. If it does slide off the idler can

E. Cleaning the Pump - A clean pump is easier to inspect, lubricate, adjust, and runs cooler.

F. Storage - If pump is to be stored or not used for six months or more, pump must be drained, and a light coat of non-detergent SAE 30 weight oil must be applied to all internal pump parts. Lubricate fittings and apply grease to pump shaft extension. Viking suggests rotating pump shaft by hand one complete revolution every 30 days to circulate the oil. Retighten all gasketed joints before using the pump.

5. DON’T operate pump without a relief valve on the pump or

© Viking Pump, Inc.

6. DON’T exceed catalog limits for temperature and pressures of fluids in jacketed areas of pump.

7. DON’T use the pump in a system which includes a steam, air, or vapor blow or purge without provision for overspeed shutdown, in case the pump starts to act as a turbine and over-speeds the drive.

8. DON’T operate the pump with all of the liquid bypassing through a pump mounted internal type relief valve, or without any flow of liquid going through the pump for more than a couple of minutes. Operation under either of these conditions may result in a heat build-up in the pump, which

MAINTENANCE

1. DO make sure any pump that has residual system pressure in it, or that has handled high vapor pressure liquids, such as LP-gas, ammonia, Freons, etc., has been vented through the suction or discharge lines or other openings provided for this purpose.

© Viking Pump, Inc.

2. DO make sure that if the pump is still hooked to the driver while maintenance is being performed that the driver has been “locked out”, so that it cannot be inadvertently started while work is being done on the pump.
