2PE Series Aluminum Gear Pump, 0.40 cu in/rev, 2-Bolt SAE A Mounting Flange, 5/8 St. Keyed x 1.25, SAE A Shaft, SAE -12 Inlet, SAE -10 Outlet, CW Rotation

Continuous working pressure on this unit is rated up to 3600 PSI, but it can handle peak spikes up to 4350 PSI for short durations. For anything running at or above 2900 PSI continuously, you'll want your filtration cleaned up to ISO 4406 level 19/18/15. Below that threshold, 20/19/16 is acceptable. Keep those numbers in mind when sizing your circuit, because pushing a gear pump past its continuous rating for extended periods will wear it down faster than it should.

This gear pump works best with fluid viscosities ranging from 85 SUS to 297 SUS for normal operation. It can handle minimum viscosities of 66 SUS (with reduced pressure and speed) up to a maximum starting viscosity of 3635 SUS.
