This vintage Berkeley centrifugal irrigation pump is PTO-driven from a tractor, designed for high-volume water transfer in ag settings. Based on its features—like the 3x4 priming valve and overall construction—it aligns with models such as the T1-B3ZRM, capable of 300–700 GPM under typical conditions.
Key features and specs:
Large exposed belt pulley with guard for tractor or engine drive.
3x4 automatic discharge priming valve (casting L3671) for efficient startup.
Hand diaphragm primer (galvanized silver piece with handle) – had a new diaphragm installed last time it was used.
Link-Belt self-aligning ball bearings (size 1-3/4", No. P-228) – heavy-duty and original.
Horizontal suction/discharge ports (3" inlet, 4" outlet) for high-volume water movement.
