4 Makepipe run short, straight and with as few pipe fittings as pos-sible, to keep total friction loss to a pump in a clean, dry and drained location if possibleand protect against moisture and adverse weather should be located on a level, hard surface to preventshifting or tipping. Locate to be readily accessible for in-spection and of the portable nature of this style pump, carefulattention should be taken to assure that Net Positive SuctionHead Available (NPSHA) exceeds Net Positive Suction HeadRequired (NPSHR) by the pump or reduced performance andsevere pump damage may result. Figure 1, illustrates where these terms (NPSHA / NPSHR)come from, and how to determine if the pumping conditions atwhich you want to operate meet the proper criteria.

5 When indoubt, consult your nearest Berkeley Professional : If pump site is 1000 feet above sea level, subtract from the NPSHA equation and an additional feet foreach additional 1000 feet of FOUNDATIONCRUSHING with largersuction and discharge openings are extremely heavy. Use careand proper equipment when handling pump for sure to allow for the weight of the water in the pump installation :Pump should be placed on an area that will provide a solidfoundation substantial enough to support the weight of pumpand engine and also to provide stability while the pump isrunning. engine vibration will cause shifting on any type ofloose surface and cause piping strains and possible : Settling and/or shifting during operation can causepiping to place excessive strain on the pump and maydamage pump installation :Pump and engine should be set on a concrete foundationwhich is sufficiently substantial to absorb vibration and whichwill provide a permanent and rigid support.

6 Bolt engine directlyto piping should be at least one commercial pipe sizelarger than pump connections and flow velocity should notexceed eight (8) feet per of piping with pump case orexcessive pipe strain can cause distortion of pump com-ponents resulting in rubbing, breakage and reduced pump life. Insure that piping is supported in a manner that prevents theexertion of force on pump connections. If ANSI type flangeconnections are used, this can be checked by the followingprocedure. With the pump shut down, remove pipe flangebolts. If the mating flanges come apart or shift, misalignmentis present and causing pressure on the connections.

The operating head-capacity pointshould be as close as possible to the highest efficiency lineshown on the performance curve, and MUST be below thehead-capacity line labeled Maximum RPM.

9 The maximumoperating RPM for the pump is determined by bearing life, orin some cases, by the pressure limits of the pump. Themaximum working pressure for NPT tapped and flangedpumps, per ANSI class 125, is 175 PSI unlessotherwise stated on the pump curve . When used as a boosterpump, the pressure at the pump discharge (combination ofinlet pressure plus pressure added by the pump) must notexceed the maximum working pressure shown. The SuctionNPSHA must be greater than the NPSHR shown on the :The engine used to drive the pump must be suitable for theapplication. It must produce adequate power for the pumpdemand, and must rotate in the correct direction (standardrotation is CLOCKWISE when viewed from the front ofengine).

10 Internal Combustion Engines are variable speed and variablepower machines. The power output depends upon the enginespeed (RPM) and will be reduced when operating altitude,and/or the air temperature increases. When driving the pumpat the RPM required to deliver water into the system piping,the engine must operate within the engine manufacturersminimum and maximum RPM limits. The power output tosupply the pump power demand must not exceed theCONTINUOUS POWER RATING of the engine , after deratingfor all power consuming engine accessories, and adjustmentfor installation site altitude and air temperature. Proper powermatching of the pump and engine is the responsibility of thepump and engine unit PUMP END TO Bracket Size:Type B engine drive pumps are available to fit engineshaving a standard 5 through 1 flywheel a new engine , the engine supplier can provide the an existing engine , the flywheel housing bore and boltcircle can be measured and compared against the housing dimensions listed in Table I, to identify thehousing number.
