Water Truck Pump B4ERBMS, 5" Suction x 4" Discharge Flanged, Clockwise (CW), Mechanical Seal, Berkeley B73023

The Berkeley OEM B73023 Water Truck Pump (Model B4ERBMS) 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, construction equipment, and industrial fluid handling systems.

Constructed with a cast iron volute and impeller, this pump is engineered to handle demanding conditions. It features a mechanical shaft seal for reliable, leak-resistant operation and a clockwise (CW) rotation. The enclosed impeller and precision volute design maximize hydraulic efficiency and flow performance.

Unlike self-priming models, this pump is designed for flooded suction systems, making it ideal for tank-fed applications where consistent prime is maintained.
