Installation | Receiving Pump | Storage | Location Setting Baseplate/Pedestal | Alignment Procedure INSTALLATION When installing the pump, consider its location in relation to the system to assure that sufficient Net RECEIVING PUMP Positive Suction Head (NPSH) at pump suction is provided. -
Page 5: Suction And Discharge Piping
Suction and Discharge Piping b) It is usually advisable to increase the size of When installing valves in the suction piping, both suction and discharge pipes at the pump observe the following precautions: connections to decrease the loss of heat from friction. -

Page 9: Troubleshooting
Troubleshooting No liquid delivered CAUSES CURES 1. Lack of prime Fill pump and suction pipe completely with liquid. 2. Loss of prime Check for leaks in suction pipe joints and fittings; vent casing to remove accumulated air. 3. Suction lift too high If no obstruction at inlet, check for pipe friction losses. - Page 10 Troubleshooting Not enough liquid delivered CAUSES CURES 17. Foot valve too small or partially Area through ports of valve should be at least as large as area obstructed of suction pipe, preferably 1½ times. If strainer is used, net clear area should be 3 to 4 times area of suction pipe. 18.
