Berkeley B73023 5x4 CW Water Pump - Mechanical Seal, Shaft Drive

## Berkeley B73023 5x4 CW Water Pump - Mechanical Seal, Shaft Drive The Berkeley B73023 B4ERBMS is a heavy-duty 5" x 4" centrifugal water pump designed for high-volume water truck and industrial water transfer applications. This clockwise (CW) configuration features flanged suction and discharge connections, a mechanical shaft seal, and a frame-mounted shaft-drive design. Built with a heavy-duty cast iron volute and impeller, the B4ERBMS is designed for demanding applications requiring high flow and dependable operation. The mechanical seal provides reliable, leak-resistant shaft sealing, while the frame-mounted design allows the pump to be driven mechanically through a coupling or other compatible shaft-drive system. The pump uses a flooded-suction design, making it ideal for tank-fed water truck systems where the pump is mounted below the water level to maintain prime. ### Features * Genuine Berkeley OEM water pump * Heavy-duty B4ERBMS centrifugal pump * 5" suction x 4" discharge * Flanged inlet and outlet connections * Clockwise (CW) rotation * Mechanical shaft seal * Frame-mounted shaft-drive design * Cast iron volute and impeller * Enclosed impeller design * Designed for high-volume water transfer * Flooded-suction, non-self-priming design * Ideal for heavy-duty water truck applications ### Specifications **Manufacturer:** Berkeley **Berkeley Part Number:** B73023 **Model:** B4ERBMS **Pump Type:** Single-Stage Centrifugal Water Pump **Size:** 5" x 4" **Suction:** 5" Flanged **Discharge:** 4" Flanged **Rotation:** Clockwise (CW) **Seal Type:** Mechanical Seal **Drive Type:** Shaft / Coupling Drive **Mounting:** Bearing Frame Mount **Volute:** Cast Iron **Impeller:** Cast Iron **Impeller Diameter:** 10.44" **Pump Design:** Flooded Suction / Non-Self-Priming **Application:** Water Truck / High-Volume Water Transfer ### Water Truck Applications The Berkeley B73023 is well suited for larger water trucks and applications requiring significantly higher water volume than traditional 4" x 3" water truck pumps.
