RESULT IN DAMAGE TO PUMP AND/OR OTHER EQUIPMENT.

THIS INFORMATION MUST BE FULLY READ BEFORE

BEGINNING INSTALLATION, OPERATION OR MAINTENANCE

OF PUMP, AND MUST BE KEPT WITH PUMP. PUMP MUST BE

© Viking Pump, Inc.

THE FOLLOWING SAFETY INSTRUCTIONS MUST BE FOLLOWED AND ADHERED TO AT ALL TIMES.

DANGER = FAILURE TO FOLLOW THE INDICATED

INSTRUCTION MAY RESULT IN SERIOUS INJURY

OR DEATH.

WARNING = IN ADDITION TO SERIOUS INJURY OR DEATH,

FAILURE TO FOLLOW THE INDICATED INSTRUCTION MAY

CAUSE DAMAGE TO PUMP AND/OR OTHER EQUIPMENT

DANGER

⚠ WARNING

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

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

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

© Viking Pump, Inc.

⚠ WARNING

• 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.

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

© Viking Pump, Inc.

BEFORE operating the pump, be sure all drive guards are in place.

DANGER

DO NOT attempt to dismantle a pressure relief valve that has not had the spring pressure relieved or is mounted on a pump that is operating.

DANGER

© Viking Pump, Inc.

operate pump if the suction or discharge piping is not connected.

DANGER

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

⚠ WARNING

DO NOT exceed the pumps rated pressure, speed, and

© Viking Pump, Inc.

suitability for the new service.

⚠ 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.

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.

®

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

⚠ WARNING

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.

SPECIAL INFORMATION

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.

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

© Viking Pump, Inc.

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 connections are connected to the suction or discharge port as noted above to avoid excessive leakage or damage to pump.

If pump is handling heated product, be sure circulation line is

© Viking Pump, Inc.

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.

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.

models designed to accept a relief valve. Options may 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

8 . If pump rotation is reversed, remove pressure relief

valve and turn end for end.

For additional information on pressure relief valves, Refer to

Appendix , General Installation Notes , item 5 on Pressure

Protection or contact your Viking Pump ® representative for

Engineering Service Bulletin ESB-31.

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.

MAINTENANCE

These pumps are designed for long, trouble-free service life under a wide variety of application conditions with minimum maintenance. The points listed below will help provide long service life.

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

New packed pumps require initial packing adjustment to control leakage as packing “runs in”. Make initial adjustments carefully and do not over -tighten packing gland. After initial adjustment, inspection will reveal need for packing gland adjustment or packing replacement. Contact your Viking

Pump ® representative for Engineering Service Bulletin

ESB-521 regarding repacking pump.

CLEANING PUMP

Keep pump as clean as possible. This will facilitate inspection, adjustment and repair work and help prevent overlooking a dirt covered grease fitting.

© Viking Pump, Inc.

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. Tighten all pump assembly bolts before putting pump in service after being stored.

SUGGESTED REPAIR TOOLS

The following tools must be available to properly repair these

Avoid damaging head gasket. Back head slightly away from casing. Do not allow idler to fall from idler pin. To prevent this, tilt top of head back when removing. Remove head from pump. A lifting hook for N, R & RS size pumps will provide adequate connection for hoisting head. If a hoist is not available, cribbing or blocking can be used to support head. This will eliminate having to lift head into position when reassembling pump.

If pump is furnished with pressure relief valve, it need not be removed from head or disassembled at this point; however, removing relief valve will lessen total weight of part. Do not use chain or cable around relief valve body to

support head during removal. Refer to "Pressure Relief

GENERAL INSTALLATION NOTES

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

1. Location - always locate the pump as close as possible

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

© Viking Pump, Inc.

Figure A2 ; some models are available available with the right angle ports located in any one of eight positions including right-hand and left-hand.

4. Suction/Discharge - shaft rotation will determine which port is suction and which is discharge. A look at Figure

A3 will show how rotation determines which port is which.

As the pumping elements (gears) come out of mesh, point

“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.

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.

liquid flows through until a pressure is reached at which all of the liquid being pumped is going through the valve. This pressure is the relief valve setting.

Suction

Valve Always Mounts on Discharge Side of

Pump

Viking pumps can be furnished with either an internal pressure relief valve - one which directs the flow from the valve back to the suction side of the pump - or a returnto-tank valve - which directs the flow through piping back 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.

CAUTION !

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 return-to-tank type to the other port. If on a particular installation rotation is reversed, e.g., using one pump 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 spring-loaded poppet-type valve is strictly a differential 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.

© Viking Pump, Inc.

© Viking Pump, Inc.

© Viking Pump, Inc.

CAUTION !

Pumps or systems without relief valves should have some form of pressure protection, e.g. torque limiting devices or rupture disks.

FOUNDATION

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.

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

mounted directly on the pump, an inline relief valve, a torque limiting device or a rupture disk.

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

COMPONENT & UNIT LIFTING

FEATURES

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

ALIGNMENT PIPING

© Viking Pump, Inc.

© Viking Pump, Inc.

© Viking Pump, Inc.

CHECK ALIGNMENT AFTER MOUNTING

For detailed coupling alignment procedures see coupling manufacturers’ recommendations.

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,

time they were assembled. During shipping and mounting the alignment is often disturbed. BE SURE TO RECHECK

ALIGNMENT AFTER THE PUMP UNIT IS INSTALLED!

Viking General Catalog Section 510 system, consider the following points:

.

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

1. Check pump ports to be sure they are square and in the proper position; shim or move the pump as required. Do not force piping to line up with the ports.

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

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. 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.

© Viking Pump, Inc.

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 .

it creates an air pocket. See 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.

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

Refer to item 13 in 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

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

the piping. Loops, expansion joints, or unsecured (this does not mean unsupported) runs should be used so the pump casing is not distorted.

© Viking Pump, Inc.

© Viking Pump, Inc.

FIGURE A12: REDUCER DRIVE

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

© Viking Pump, Inc.

should be made for cleaning the strainer. If the pump 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.

supports, stands, etc.

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

“Springing” or “drawing” the piping up to the pump will

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

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.

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

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.

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.

15. Provide a pressure relief device in any part of a pump and

a. When handling a cold liquid such as refrigeration ammonia that can warm up to ambient temperatures when the pump is shut off.

b. When handling a liquid such as asphalt or molasses that has to be heated before it can be pumped.

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.

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

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.

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.

11. Do not use the Viking pump to flush, pressure test or prove the system with water. Either remove the pump or

minutes than months of normal service.

12. Check to be sure all guards are in place.

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 section. If everything appears to be in order, put some liquid in the pump. This will help it prime.

© Viking Pump, Inc.

The pump can be restarted. If nothing is flowing within two minutes, stop the pump. The pump is not a compressor; it will not build up much air pressure. It may be necessary to vent the discharge line until liquid begins to flow.

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

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

TROUBLESHOOTING

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

POSSIBLE SOLUTION

Flush the system with the pump removed. Install strainer in suction line. Most abrasive objects and particulate is removed after a few cycles (or days) of flushing.

Check the Viking General

Catalog Liquid List for materials of construction recommendation.

Consider whether all of the materials used in pump construction were attacked; consider other materials used in the system to determine how they resisted the liquid. Check to see whether or not the liquid has been contaminated to make it more corrosive than anticipated.

2. Strainer partially clogged.

4. Running too slowly. Check the motor is running at the correct speed and that it is wired correctly.

3

Noisy operation, broken bushings, twisted shaft, parts show evidence of high heat (discoloration).

Review General Catalog for operating limits on particular model involved.

5. Bypass line around pump partially open.

6. Relief valve set too low or stuck open.

7. Pump is worn out.

8. Too much end clearance.

9. Head position incorrect. See Figure A3 .

E. Pump takes too much power.

Noisy bearings, localized heating at bearings or lip seal, smoke, rapid bushing wear.

Be sure all grease fittings are greased before starting, and instructions for lubrication of drive equipment are followed; consider use of auxiliary lubricating equipment.

2. The liquid is too viscous for the size of the unit. Heat the liquid to reduce viscosity, increase the pipe size, slow down the pump, or use a larger motor.

3. Discharge pressure higher than calculated. Verify with a pressure gauge. Increase size or reduce length of pipe, reduce speed (capacity), or get bigger motor.

4. Packing gland drawn down too tight.

5. Pump misaligned.

Pump stalls because parts have uneven expansion caused by frictional heat; galling between surfaces having relative motion; seal seats and idler pins changing color because of high heat.

Be sure there is liquid in the system at the time of start up.

Provide some kind of automatic alarm or shut-off if supply tank runs dry.

8. Bushings have locked to shaft or pin, or the liquid has set up in the pump.

F. Rapid Wear.

On most applications the pump will operate for many months or years before it gradually loses its ability to deliver capacity or pressure. Examination of such a pump would show a smooth wear pattern on all parts. Rapid wear, occurring in a few minutes, hours or days, shows up as heavy grooving, galling, twisting, breaking or similar

PREVENTATIVE MAINTENANCE DO’S & DON’TS

© Viking Pump, Inc.

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.

© Viking Pump, Inc.

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.

Use a NLGI #2 grease for normal applications. See

ESB-515 at the end of the Appendix for Viking standard grease types to check compatibility. For hot or cold applications, use appropriate grease.

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

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.

1. DO install pump as close to supply tank as possible.

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.

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.

© Viking Pump, Inc.

OPERATION

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

© Viking Pump, Inc.

C. End Clearance Adjustment - After long service, the running clearance between the end of the rotor teeth and the head may have increased through wear. This wear may cause a loss of capacity or pressure. Resetting end clearance will normally improve pump performance.

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

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.

8. DON’T stick fingers in the ports of a pump. Serious injury may result.

9. DON’T spin the idler on the idler pin. Fingers may be jammed between teeth and crescent.

Reservoir on Ammonia Pumps: The Series 4924A ammonia pumps are shipped without oil in the reservoir. Before startup, fill the reservoir with one pint of Light Refrigeration Oil that is compatible with the Neoprene seal and with a maximum viscosity of 15,000 SSU at operating temperature. Drain and refill the reservoir after the first 200 hours of operation and every 1000 hours thereafter. Refer to Technical Service

Manual TSM 1467.
