Do not exceed 3600rpm operating speed.1. Pumps should not be directly drivenby engines.2. Never use a rigid coupling betweena pump and its driver (electricmotor, gas engine, etc.). Somedegree of flexibility must be allowedto avoid excessive side loading ofthe drive and pump bearings.3. Flexible couplings should be ratedfor the horsepower load and speed.4. The pump and drive shaft must beproperly aligned. Misalignment willcause unnecessary loads on thepump and driver bearings. Shimsmay be used to assist in flexiblecoupling of the pump to the motor.5. Check the impeller for properrotation. When viewing the pumpinlet, the impeller should rotatecounterclockwise. Test the motoror drive for correct rotation asindicated on the pump housingprior to placing the pump in service.Safety shields arerequired and must bemounted and kept in place while power issupplied to pump drive.Belt/Pulley Drive Installation1. For pulley driven pumps, a single1/2" [12.7 mm] (A or 4L section) “V”belt is satisfactory for drive sizesand speed up to 1 HP, 3450 RPM.For larger sizes, double “V” beltsare recommended.2. Mount pulleys as close to the pumpand motor engine shaft bearings aspossible. Check alignment with astraight edge as shown in Figure 9.Make sure the belt is properlyadjusted. Too much tension willcause bearing failure and too littletension will result in belt slippage(See Figure 9). Check with the beltand pulley suppliers for specificinformation and recommendations.3. To calculate the proper diameter ofthe pump pulley, multiply the motor/engine RPM by the diameter of themotor/engine pulley and divide thatfigure by the desired pump speed.PumpMotor RPM x Motor Pulley SizePulley =SizeDesired Pump Speed4. A safety shield (belt shield)must be installed over the pump andmotor shafts, pulleys and belt.NOTE: Refer to pump performancecharts to determine the desired speedto obtain the desired maximum flow.Direct Drive – Flexible CouplingInstallation1. Slide the flexible coupling endsonto the motor/engine and pumpshafts as far as possible (seeFigure 10).2. Secure but do not tighten theengine/motor and pump to theselected base or location.3. Laser alignment of the pumpshaft and the engine/motor shaftis recommended. If this is notpossible, determine the parallelmisalignment of the pump shaftand engine/motor shaft by placinga straight edge across the shaft andmeasuring the maximum offsetaround the periphery of the shafts.Make the necessary corrections tokeep the shafts within the parallelmisalignment limits (0.015").4. When aligned, slide the flexiblecoupling ends over the flexiblecoupling center; then secure theflexible coupling ends to themotor/engine and pump shafts(see Figure 10).5. Tighten the fasteners securing thepump and engine/motor in thedesired location.6. A safety shield (coupling guard) mustbe installed over the pump andmotor shafts and coupling.Engine/MotorShaftFigure 8 - Pulley AlignmentPush the belt midwaybetween the pulleys,check the deflections(d) and adjust:d=0.016 X LFigure 9 - Belt TensionPumpShaftFlexibleCoupling EndFigure 10 - Flexible Coupling InstallationFlexibleCoupling EndFlexibleCoupling CenterForm L-4075 (12/09)6
