25VQ Series Vane Pump, 21 Ring Size, 13 Tooth SAE B Splined Shaft, Outlet 90 deg CW from Outlet, CCW Rotation

Description & Features

Designed for high-pressure, high-speed hydraulic circuits, the 25VQ Series Vane Pump, 21 Ring Size, 13 Tooth SAE B Splined Shaft, Outlet 90 deg CW from Outlet, CCW Rotation is a single vane pump from Eaton Vickers rated to 3000 PSI with a displacement of 4.12 and a speed rating of 2500 RPM. Rated flow is 31.5, and the inlet port is positioned 90 degrees clockwise from the outlet, a configuration that suits tight installation envelopes where port orientation is a constraint.

Mounting is via a 2-bolt SAE B flange, with SAE 4-bolt flange ports sized at 1-1/2" inlet and 1" outlet. The 13-tooth SAE B splined shaft provides a standard drive interface across compatible power units. Built to handle demanding duty cycles, this pump is suited for plastics machinery, press machines, die casting equipment, machine tools, test equipment, primary metal processing, pulp and paper, wood processing, oil and gas, marine, and general industrial applications. Longer service life and consistent volumetric efficiency are key design characteristics of the 25VQ series.

Product Questions & Answers (2)

Question by: Joyce M on Jan 27, 2026, 7:03 PM

got a 25VQ21A-11B20-L pump in here now, is this the same one with the CCW rotation and the SAE B splined shaft?

Answer by: Customer Support on Jan 29, 2026, 8:18 AM

Match-up wise, it lines up with model number 25VQ21A-11B20-L, CCW rotation, and a 13 tooth SAE B splined shaft in the 25VQ series with the 21 ring size.

Question by: Travis W on Sep 12, 2025, 10:16 AM

pump puts out 31.5 GPM at what speed, and is that at full 3000 PSI or just rated flow conditions?

Answer by: Customer Support on Sep 13, 2025, 7:16 PM

Rated flow of 31.5 GPM is at the 2500 RPM speed rating for this pump. The maximum pressure is 3000 PSI, so that flow figure and that pressure ceiling are both part of the same operating spec. Running it right at the pressure limit continuously is a different conversation than hitting peak flow, but both numbers come from the same design envelope on this unit.
