17b. Check and record pressure gaugereadings for future reference.c. Check and record voltage, amperage perphase, and kw if an indicating wattmeter isavailable.d. Check bearings for lubrication andtemperature. Normal temperature is 180°maximum.e. Make all pump output adjustments withthe discharge line.CAUTION: Cavitation Damage HazardDo not throttle the suction line to adjust thepump output. Failure to follow these instructionscould result in property damage and/or moderatepersonal injury.FREEZING PROTECTIONPumps that are shut down during freezingconditions should be protected by one of thefollowing methods.a. Drain the pump; remove all liquids fromthe casing.b. Keep fluid moving in the pump andinsulate or heat the pump to preventfreezing.CAUTION: Bearing/Seal Damage HazardDo not let heated pump temperature riseabove 150°F. Failure to follow these instructionscould result in property damage and/or moderatepersonal injury.FIELD TESTINGA typical performance curve for a specificpump can be obtained from ITT A-C FirePump Systems. This can be used inconjunction with a field test, if one is required.All ITT A-C Fire Pump Systems tests andcurves are based on the Hydraulic InstituteStandards. Any field test must be conductedaccording to these Standards.Unless otherwise specifically agreed, allcapacity, head, and efficiencies are based onshop tests when handling clear, cold, freshwater at a temperature not over 85°F.Appendix “C” (Pages 34-35) contains a fieldtest report sheet and some useful equationswhich can be used when conducting a fieldtest.MAINTENANCEGENERAL MAINTENANCEOperating conditions vary so widely that torecommend one schedule of preventativemaintenance for all centrifugal pumps is notpossible. Yet some sort of regular inspectionmust be planned and followed. We suggest apermanent record be kept of the periodicinspections and maintenance performed onyour pump. This recognition of maintenanceprocedure will keep your pump in goodworking condition, and prevent costlybreakdown.One of the best rules to follow in the propermaintenance of your centrifugal pump is tokeep a record of actual operating hours.Then, after a predetermined period ofoperation has elapsed, the pump should begiven a thorough inspection. The length ofthis operating period will vary with differentapplications, and can only be determinedfrom experience. New equipment, however,should be examined after a relatively shortperiod of operation. The next inspectionperiod can be lengthened somewhat. Thissystem can be followed until a maximumperiod of operation is reached which shouldbe considered the operating schedulebetween inspections.MAINTENANCE OF PUMP DUE TO FLOODDAMAGEWARNING: Unexpected Startup HazardDisconnect and lockout power beforeservicing. Failure to follow these instructions couldresult in serious personal injury or death, orproperty damage.WARNING: Electrical Shock HazardElectrical connections to be made by aqualified electrician in accordance will allapplicable codes, ordinances, and good practices.Failure to follow these instructions could result inserious personal injury or death, or propertydamage.The servicing of centrifugal pumps after aflooded condition is a comparatively simplematter under normal conditions. |
