The Berkeley B70373 B4ZRKS is a heavy-duty self-priming centrifugal water pump designed for hydraulic-drive applications requiring dependable suction and water-transfer performance. The self-priming B4Z design is well suited for water trucks, tank filling, spraying systems, water transfer, dewatering, and other mobile pumping applications.
B70373 features clockwise (CW) rotation, a direct hydraulic-drive configuration, SAE C 4-bolt hydraulic motor mount with 1-1/4" x 14-tooth spline, mechanical shaft seal, and heavy-duty cast iron construction. Its elevated suction inlet and internal check-valve design help retain prime and support suction-loading applications.
The pump uses Berkeley's B4ZRKS heavy-duty Z-frame with a 9.12" x 1.00" cast iron impeller. Berkeley identifies B70373 specifically as the hydraulic-CW configuration of the B4ZRKS self-priming pump.
