The Berkeley B69743 B4JRMBHS is a genuine Berkeley frame-mounted centrifugal pump configured for high-volume water-truck and dust-control systems. Its 5-inch suction and 4-inch discharge flanges support large plumbing systems, while the SAE C hydraulic-drive interface allows integration with a correctly sized hydraulic motor.
This clockwise-rotation configuration uses a 13.5-inch cast-iron impeller and mechanical shaft seal. At 2,400 RPM with fresh water at 68°F, the published selection reaches its best-efficiency point at approximately 1,546 GPM and 290.5 feet of head (about 126 PSI).

Confirm the pump nameplate, clockwise rotation, 5-inch x 4-inch flanged connections, SAE C 4-bolt motor mount, 1-1/4-inch 14-tooth spline, and mechanical-seal configuration. Published performance is based on fresh water at 68°F and will vary with pump speed, suction conditions, plumbing and total system resistance. Do not operate above the published 2,400 RPM hydraulic-drive range.
