This Care Manual was designed as a general guide to Berkeley centrifugal pumps and is not intended to be used as an Engineering Specifications Manual. All subjects covered, whether written or illustrated, are suggestions by Pentair to aid in the proper installation and operation of end suction centrifugal pumps and apply to no particular application.
INSTALLATION SUCTION LIFT - RECOMMENDED Short length of straight pipe after reducer. ( 2 times pipe diameter minimum ) For Han-Dee Primer Suction connection, see start-up. Gauge Straight run, short as possible but 503 0194 at least 6 times pipe diameter ("D") after elbow to stabilize flow.
INSTALLATION SUCTION LIFT - NOT RECOMMENDED Do not use Concentric Reducer. Concentric Reducer causes high spots along the suction line resulting in air pockets. 505 0194 Do not install valves in No support or suction line. uneven mounting not recommended. Unsupported pipe causes excessive stress...
INSTALLATION WHEN FLOODED SUCTION EXISTS - RECOMMENDED Water under pressure Short run of straight pipe after reducer Maintain minimum liquid (2 times pipe diameter). level to prevent vortexing. Eccentric Reducer flat side up. Suction Gauge 702 0294 Isolation Valve full open when pumping.
INSTALLATION WHEN FLOODED SUCTION EXISTS - NOT RECOMMENDED Inverted Eccentric Reducer may result in air pocket. Water under pressure Valve in upward position may trap air. Do not leave 703 0294 valve partially closed. Check Valve in suction pipe not needed. Concentric Reducer may cause air pockets.
INSTALLATION DISCHARGE CONNECTION - RECOMMENDED This view shows discharge Expansion joint with tie fittings typical of pump rods where needed. with flooded suction. Isolation Valve This fitting may be used to Use Concentric Reducer check shut-off head. 706 0294 to mimimize friction losses. Pressure Gauge Discharge pipe diameter at...
INSTALLATION DISCHARGE CONNECTION - NOT RECOMMENDED Avoid check valves that cause hydraulic shock. 708 0294 Avoid undersized pipe diameter. Do not force alignment that can cause flange stresses. Do not use Gate Valve Do not leave to throttle flow. pipe unsupported. Avoid abrupt change in pipe size.

START-UP DETERMINE PUMP ROTATION Viewed from Viewed from this direction this direction As viewed As viewed 938 0594 Pump with a Pump with a Clockwise Counter-Clockwise Rotation Rotation Pump Rotation is determined as clockwise or counter-clockwise by viewing liquid end of pump from the back or shaft side, and NOT from looking into the impeller eye or front of volute.
START-UP CHECK LIST Read and be familiar with the pump Installation, Operation and Maintenance Manual. Check to see that all aspects of these instructions have been complied with. Pipe connections must be securely fastened and air tight. All piping must be clean and free of debris. ...
MAINTENANCE THREADED SHAFT - FRAME MOUNT Unfasten hardware holding volute to bracket. Clockwise Rotation Remove volute to expose impeller. Volute shown. Peel off old volute gasket (or O-Ring) and discard. 1149 0794 NOTE: Certain models such as the B4EY, are constructed with a suction flange which is removed first to access the impeller.

Polished Face Cardboard washer (Supplied with seal) 1143 0794 1142 0794 Place bracket on a smooth, flat surface, pump side up. Cover ceramic face with cardboard washer and press ...
MAINTENANCE ROUTINE MAINTENANCE A well maintained pumping system will extend the life of the unit and require fewer repairs. This means less down-time which can be very critical when a constant delivery of liquid is required. A routine maintenance and inspection schedule should be set up on a weekly, quarterly, and annual basis with records kept of these actions.
Page 24
MAINTENANCE ROUTINE MAINTENANCE QUARTERLY Pump and Piping Connections – Inspect all system piping connections for leakage or possible misalignment. Misalignment of pipe connections to the pump will put excessive strain on the pump case and can cause damage to internal components of both the pump and motor.
MAINTENANCE RECOMMENDED SPARE PARTS The number and type of spare parts kept on hand at any pump site is dictated by the severity of the service in which the pump is used. That is, a pump servicing a golf course’ s sprinkling system should not be down because of a simple case gasket, or a subdivision out of water because of a failed mechanical seal.
