Water Truck Pump, Model B4JRMBHS, 5" Suction x 4" Discharge Flanged, Clockwise (CW), Keyed Shaft, 13.5" Impeller, Mechanical Seal, Berkeley B61050

The Berkeley OEM B61050 Water Truck Pump (Model B4JRMBHS) is a heavy-duty, frame-mounted centrifugal pump designed for high-volume water transfer in demanding applications. Featuring a 5" suction x 4" discharge flanged configuration, this pump is ideal for water trucks, dust suppression systems, and industrial fluid handling.

The Type B frame-mounted design allows for flexible installation using belt or coupling drive systems, making it a versatile choice for a wide range of builds.

Built with all cast iron construction and a 13"–13.5" enclosed impeller, this pump is engineered for efficient flow and pressure performance. It features a mechanical shaft seal for dependable, leak-resistant operation and a clockwise (CW) rotation.

This model is designed for flooded suction systems (non self-priming), making it ideal for tank-fed water truck applications where consistent prime is maintained.
