SAFETY INSTRUCTIONSTO AVOID SERIOUS OR FATAL PERSONAL INJURYOR MAJOR PROPERTY DAMAGE, READ ANDFOLLOW ALL SAFETY INSTRUCTIONS IN MANUALAND ON PUMP.THIS MANUAL IS INTENDED TO ASSIST IN THEINSTALLATION AND OPERATION OF THIS UNITAND MUST BE KEPT WITH THE PUMP.DANGERWARNINGCAUTIONThis is a SAFETY ALERT SYMBOL.When you see this symbol on the pumpor in the manual, look for one of the followingsignal words and be alert to thepotential for personal injury or propertydamage.Warns of hazards that WILL causeserious personal injury, death or majorproperty damage.Warns of hazards that CAN causeserious personal injury, death or majorproperty damage.Warns of hazards that CAN cause personalinjury or property damage.NOTICE: INDICATES SPECIAL INSTRUCTIONSWHICH ARE VERY IMPORTANT ANDMUST BE FOLLOWED.THOROUGHLY REVIEW ALL INSTRUCTIONSAND WARNINGS PRIOR TO PERFORMING ANYWORK ON THIS PUMP.MAINTAIN ALL SAFETY DECALS.WARNINGHazardous fluidscan cause fire,burns or death.UNIT NOT DESIGNED FOR USEWITH HAZARDOUS LIQUIDS ORFLAMMABLE GASES. THESEFLUIDS MAY BE PRESENT INCONTAINMENT AREAS.DESCRIPTION & SPECIFICATIONS:The Models NPE (close-coupled) and NPE-F (framemounted)are end suction, single stage centrifugal pumpsfor general liquid transfer service, booster applications,etc. Liquid-end construction is all AISI Type 316 stainlesssteel, stamped and welded. Impellers are fully enclosed,non-trimable to intermediate diameters. Casings are fittedwith a diffuser for efficiency and for negligible radial shaftloading.Close-coupled units have NEMA 48J or 56J motors withC-face mounting and threaded shaft extension. Framemountedunits can be coupled to motors through a spacercoupling, or belt driven.1. Important:1.1. Inspect unit for damage. Report any damage to carrier/dealerimmediately.1.2. Electrical supply must be a separate branch circuitwith fuses or circuit breakers, wire sizes, etc., pernational and local electrical codes. Install an all-legdisconnect switch near pump.CAUTIONAlways disconnect electrical power whenhandling pump or controls.1.3. Motors must be wired for proper voltage. Motor wiringdiagram is on motor nameplate. Wire size mustlimit maximum voltage drop to 10% of nameplatevoltage at motor terminals, or motor life and pumpperformance will be lowered.1.4. Always use horsepower-rated switches, contactor andstarters.1.5. Motor Protection1.5.1. Single-phase: Thermal protection for singlephaseunits is sometimes built in (check nameplate).If no built-in protection is provided, usea contactor with a proper overload. Fusing ispermissible.1.5.2. Three-phase: Provide three-leg protection withproperly sized magnetic starter and thermaloverloads.1.6. Maximum Operating Limits:Liquid Temperature: 250º F (120º C)Pressure:125 PSIStarts Per Hour: 20, evenly distributed1.7. Regular inspection and maintenance will increaseservice life. Base schedule on operating time. Refer toSection 8.2. Installation:2.1. General2.1.1. Locate pump as near liquid source as possible(below level of liquid for automatic operation).2.1.2. Protect from freezing or flooding.2.1.3. Allow adequate space for servicing and ventilation.2.1.4. All piping must be supported independently ofthe pump, and must “line-up” naturally.CAUTIONNever draw piping into place by forcing thepump suction and discharge connections.2.1.5. Avoid unnecessary fittings. Select sizes to keepfriction losses to a minimum.2.2. Close-Coupled Units2.2.1. Units may be installed horizontally, inclined orvertically.CAUTIONDo not install with motor below pump.Any leakage or condensation will affectthe motor.2.2.2. Foundation must be flat and substantial toeliminate strain when tightening bolts. Userubber mounts to minimize noise and vibration.2.2.3. Tighten motor hold-down bolts beforeconnecting piping to pump.2.3. Frame-Mounted Units2.3.1. It is recommended that the bedplate be groutedto a foundation with solid footing. Refer toFigure 1.3
