Berkeley B59539

Berkeley B59539 Frame-Mount Pump

The Berkeley B3ZRM (B59539) is a heavy-duty hydraulic-driven frame mount centrifugal pump purpose-built for water trucks, tanker tenders, and high-volume water transfer applications. Powered by a customer-supplied SAE hydraulic motor, its one-piece motor mount casting delivers direct, precision-aligned coupling for maximum reliability — even under continuous-duty conditions.

With a maximum flow of 800 GPM (48,000 GPH) and a 4" inlet, this is one of Berkeley's highest-capacity B-frame hydraulic pumps. The B07779 Hydraulic Motor Drive Adapter is included, making this a complete, ready-to-mount solution.

Key Features:

  • 20,000+ Hour Bearing Life: Industry-leading ball bearing design built for continuous-duty operation on water trucks and tenders.
  • Versatile Seal Housing: The interchangeable seal housing allows for easy in-field seal changes—from packing to mechanical or mechanical to packing—providing flexibility and simplifying maintenance.
  • Durability & Efficiency: Water Truck & Tender Ready: Engineered for tanker truck mounting in continuous duty — note: not compatible with PTO or shaft coupling drive.
  • Clockwise Rotation: As viewed from the drive end. For CCW rotation, see model B59538.

Common Applications: Water trucks & tenders · Construction site water supply · Dust suppression · Agricultural irrigation · Fire suppression support · Industrial water transfer

For performance options, refer to the impeller size and RPM performance curve.

Hydraulic Motor Requirements:
The hydraulic motor must have and SAE Standard (SAE J744C) mounting flange and shaft size [B], with 30° involute spline, 13T, 16/32 pitch.

Note: The image does not show the installed hydraulic kit. Please see the images below for more details. The B07779 Hydraulic Motor Drive Adapter is included.

The Berkeley B3ZRM Water Truck Pump B3ZR Hydraulic B59539 (B59539) is a hydraulically driven frame-mount pump engineered for water trucks, tankers, and mobile equipment that run off a hydraulic power source. With Hydraulic CW Packing NPT, this pump delivers strong, consistent flow without relying on a dedicated electric motor, making it ideal for vehicle-mounted water delivery and dust suppression.
