Please inspect the pump upon arrival for any damage that may have occurred during shipment. Report any damage immediately to the carrier. Leave all shipping covers attached to the pump unit until it is ready for installation. If installation is to be delayed more than 15 days, the pump shaft should be rotated by hand once a week to lubricate the bearings and prevent rusting. Choosing Pump Location The following recommendations may be helpful when choosing the best location for your pump. a. Locate the pump as close to the liquid source as practical so the intake pipe is short and direct with a minimum of elbows, fittings and valves. b. Place the pump in a location so the unit is accessible for inspection during operation as well as for maintenance operations involving removal and disassembly. Foundation The foundation should be sufficient to absorb any vibration and to form a permanent, rigid support for the baseplate. This is important to maintain the correct alignment of the direct connected unit. A concrete foundation on a solid base is satisfactory. Foundation bolts of the proper size should be embedded in the concrete located as indicated on the outline drawing. Aiignment The pump and motor are aligned at the factory before shipment. Realignment may be necessary after the complete unit has been leveled on the foundation and after the foundation bolts have been tightened. Procedures for checking and aligning the pump components may be found in the Hydraulic Institute Standards. Piping Both suction and discharge pipes should be supported independently near the pump so when the flange bolts are tightened no strain will be transmitted to the pump casing. Discharge Piping A valve should be installed in the discharge line to prevent fluid from flowing back through the pump when it is shut down. The valve should block the discharge line during maintenance. Suction Piping Care should be taken in sizing and locating suction piping to prevent cavitation. A valve should be installed in the intake line to prevent fluid from flowing into the pump when it is shutdown. Auxiiiary Piping - Purge Piumbing When required, purge piping is supplied with the pump. External connection should be made at the pump so purge flow can be varied as required by valving and the pressure can be monitored. Piping fittings and gauges must be corrosion resistant to the fluid being pumped.
