- Page 10 S E C T I O N I N S TA L L AT I O N & S TA R T U P Pump Location It is always best to minimize suction line losses, so the best location for any pump is as close as practical to the liquid supply source.
- Page 11 I N S TA L L AT I O N & S TA R T U P Pressure Relief This is a positive-displacement pump. As such, for each shaft revolution, it will move a specific volume of fluid from the suction side to the discharge side. If the discharge line is severely restricted or blocked, a dangerous increase in pressure and drive torque will occur rapidly between the discharge port and the restriction, which will lead to one or more of the following events:...

- Page 13 I N S TA L L AT I O N & S TA R T U P Be sure the suction piping is air-tight. Air leakage into the suction line can cause low flow, noise (similar to cavitation) and priming problems. Shaft Alignment Accurate alignment of the pump shaft and driver shaft is essential for optimal reliability and durability.
