Please inspect the pump upon arrival for any damage that might 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 for 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. c. The Wilfley slurry pump has no suction and, therefore, must be set below the supply so the material to be pumped will flow into it by gravity. A hopper bottom, intake sump or tank should be provided. Intake pipe from sump should slope and be as short as possible. Do not pump from one pump directly into a second pump, but provide an intake sump for each one. Foundation The foundation should be sufficient to absorb any vibration and to form a permanent, rigid support for the baseplate. 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. Allow ample room for changing of pump parts because these parts are sometimes very heavy. Support the piping independently and be sure to consider thermal expansion and loading. The discharge line should have sufficient spring to allow the discharge keeper to be raised about one half inch. Intake pipe may be connected to either or both sides of the pump and need not be disturbed to change the pumping parts or the bearing unit. 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 or intake chamber. 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.
