SAFETY INFORMATION & INSTRUCTIONSIMPROPER INSTALLATION, OPERATION OR MAINTENANCEOF PUMP MAY CAUSE SERIOUS INJURY OR DEATH, AND/ORRESULT IN DAMAGE TO PUMP AND/OR OTHER EQUIPMENT.VIKING’S WARRANTY DOES NOT COVER FAILURE DUE TOIMPROPER INSTALLATION, OPERATION OR MAINTENANCE.THIS INFORMATION MUST BE FULLY READ BEFOREBEGINNING INSTALLATION, OPERATION OR MAINTENANCEOF PUMP, AND MUST BE KEPT WITH PUMP. PUMP MUST BEINSTALLED, OPERATED AND MAINTAINED ONLY BY SUITABLYTRAINED AND QUALIFIED PERSONS.THE FOLLOWING SAFETY INSTRUCTIONS MUST BE FOLLOWED AND ADHERED TO AT ALL TIMES. DANGER FAILURE TO FOLLOW THE INDICATEDINSTRUCTION MAY RESULT IN SERIOUS INJURYOR DEATH. DANGERBEFORE opening any liquid chamber (pumping chamber,reservoir, relief valve adjusting cap fitting, etc.) be sure that: Any pressure in the chamber has been completely ventedthrough the suction or discharge lines or other appropriateopenings or connections. The pump drive system (motor, turbine, engine, etc.) hasbeen “locked out” or otherwise been made non-operational,so that it cannot be started while work is being done onthe pump. You know what material the pump has been handling,have obtained a material safety data sheet (MSDS) forthe material, and understand and follow all precautionsappropriate for the safe handling of the material. DANGERBEFORE operating the pump, be sure all drive guards are inplace. DANGERDO NOT operate pump if the suction or discharge piping isnot connected. DANGERDO NOT place fingers into the pumping chamber, or itsconnection ports, or into any part of the drive train if there isany possibility of the pump shaft being rotated. WARNINGDO NOT exceed the pumps rated pressure, speed, andtemperature, or change the system/duty parameters fromthose the pump was originally supplied, without confirming itssuitability for the new service. WARNINGBEFORE operating the pump, be sure that: It is clean and free from debris. All valves in the suction and discharge pipelines are fullyopened. All piping connected to the pump is fully supported andcorrectly aligned with the pump. Pump rotation is correct for the desired direction of flow.TSM 1400 Issue B Page 2 of 25 WARNING IN ADDITION TO SERIOUS INJURY OR DEATH,FAILURE TO FOLLOW THE INDICATED INSTRUCTION MAYCAUSE DAMAGE TO PUMP AND/OR OTHER EQUIPMENT WARNINGINSTALL pressure gauges/sensors next to the pump suctionand discharge connections to monitor pressures. WARNINGUSE extreme caution when lifting the pump. Suitable liftingdevices should be used when appropriate. Lifting eyesinstalled on the pump must be used only to lift the pump, notthe pump with drive and/or base plate. If the pump is mountedon a base plate, the base plate must be used for all liftingpurposes. If slings are used for lifting, they must be safely andsecurely attached. For weight of the pump alone (which doesnot include the drive and/or base plate) refer to the VikingPump product catalog. DANGERDO NOT attempt to dismantle a pressure relief valve that hasnot had the spring pressure relieved or is mounted on a pumpthat is operating. DANGERAVOID contact with hot areas of the pump and/or drive.Certain operating conditions, temperature control devices(jackets, heat-tracing, etc.), improper installation, improperoperation, and improper maintenance can all cause hightemperatures on the pump and/or drive. WARNINGTHE PUMP must be provided with pressure protection. Thismay be provided through a relief valve mounted directly onthe pump, an in-line pressure relief valve, a torque limitingdevice, or a rupture disk. If pump rotation may be reversedduring operation, pressure protection must be provided onboth sides of pump. Relief valve adjusting screw caps mustalways point towards suction side of the pump. If pumprotation is reversed, position of the relief valve must bechanged. Pressure relief valves cannot be used to controlpump flow or regulate discharge pressure. For additionalinformation, refer to Appendix, General Installation Notes,item 5 on Pressure Protection or contact your Viking Pump representative for Engineering Service Bulletin ESB-31. WARNINGTHE PUMP must be installed in a manner that allows safeaccess for routine maintenance and for inspection duringoperation to check for leakage and monitor pump operation. 2020 Viking Pump, Inc.

INTRODUCTIONPRESSURE RELIEF VALVESThe illustrations used in this manual are for identificationpurposes 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 andmaterial with the model number and serial number of pumpwhen ordering repair parts. The unmounted pump or pumpunit 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 andrecommendations are listed in the Catalog Sections, whichare available at vikingpump.com.SPECIAL INFORMATIONROTATIONViking pumps can operate equally well in a clockwise orcounter-clockwise rotation; however, some constructionsmay require modifications. Consult your Viking Pump representative if unsure. Shaft rotation determines whichport is suction and which is discharge. Suction port is wherepumping elements (gear teeth) come out of mesh.If pump rotation is reversed during operation, pressureprotection must be provided on both sides of pump.Relief valve adjusting screw cap must always point towardssuction side of pump. If pump rotation is reversed, removepressure relief valve and turn end for end.CIRCULATION LINESThis equipment (not utilized on all pumps) must be connectedproperly. Packed pumps typically have a flush line frompacking chamber to discharge port. Mechanical sealpumps typically have a suckback line from seal chamber tosuction port. If pump rotation is reversed, be sure circulationconnections are connected to the suction or discharge port asnoted above to avoid excessive leakage or damage to pump.If pump is handling heated product, be sure circulation line isinsulated to assure continued flow.JACKETED PORTSJackets are utilized to heat (or cool) the pump and liquid in thepump prior to startup. Not all pumps have ports for jacketing.Jacketing port locations vary by model.FIGURE 5: RELIEF VALVE POSITIONDischargeSuction1. Viking pumps are positive displacement pumps and must beprovided with some sort of pressure protection. This may be arelief valve mounted directly on the pump, an inline pressurerelief valve, a torque limiting device or a rupture disk.2. There are relief valve options available on those pumpmodels designed to accept a relief valve. Options mayinclude a jacketed relief valve or return to tank relief valve.3. If pump rotation is reversed during operation, pressureprotection must be provided on both sides of pump.4. Relief valve adjusting screw cap must always pointtowards suction side of pump, see "Figure 5" on page15. If pump rotation is reversed, remove pressure reliefvalve and turn end for end.5. Pressure relief valves cannot be used to control pump flowor regulate discharge pressure.For additional information on pressure relief valves, Refer toAppendix, General Installation Notes, item 5 on PressureProtection or contact your Viking Pump representative forEngineering Service Bulletin ESB-31.MECHANICAL SEALSExtra care should be taken in repair of pumps withmechanical seals. Be sure to read and follow all specialinstructions supplied with your pump.MAINTENANCEThese pumps are designed for long, trouble-free service lifeunder a wide variety of application conditions with a minimumof maintenance. The points listed below will help provide longservice life.LUBRICATIONExternal lubrication must be applied slowly with a handgun to all lubrication fittings every 500 hours of operationwith multi-purpose grease, NLGI # 2. Contact your VikingPump representative with specific lubrication questions.Engineering Service Bulletin ESB-515 is located in theAppendix for standard grease thickener types used by Vikingto check compatibility. Applications involving very high or lowtemperatures will require other types of lubrication. O-Pro seals should also be greased every 500 hours of operation witha lubricating fluid compatible with the process fluid.PACKING ADJUSTMENTNew packed pumps require initial packing adjustment tocontrol leakage as packing “runs in”. Make initial adjustmentscarefully and do not over -tighten packing gland. After initialadjustment, inspection will reveal need for packing glandadjustment or packing replacement. Contact your VikingPump representative for Engineering Service Bulletin ESB521 regarding repacking pump.CLEANING PUMPKeep pump as clean as possible. This will facilitate inspection,adjustment and repair work and help prevent overlooking adirt covered grease fitting.Relief Valve Adjusting Screw Cap 2020 Viking Pump, Inc.
