Water Pump, Model B4JRMBHS, 5" Suction x 4" Discharge Flanged, Clockwise (CW), Hydraulic Drive SAE C 4-Bolt 1-1/4" x 14T, 13" Impeller, Mechanical Seal, Berkeley B69743

The Berkeley OEM B69743 Water Truck Pump (Model B4JRMBHS) is a high-performance, heavy-duty centrifugal water truck pump designed for large-capacity and high-pressure applications. Featuring a 5" suction x 4" discharge flanged configuration, this pump is ideal for off-road water trucks, mining operations, and demanding dust suppression systems.

The frame-mounted design with all cast iron construction ensures strength under continuous operation, while the 13.5" enclosed impeller is engineered for efficient flow and pressure performance.

This model is configured with a hydraulic drive (SAE C 4-bolt) and clockwise (CW) rotation, using a 1-1/4" 14-tooth splined shaft for direct coupling to a hydraulic motor. The mechanical seal design provides dependable, leak-resistant operation in harsh environments.
