Ask A Question

Description & Features

Designed for high-pressure, high-speed hydraulic circuits, the 25VQ Series Vane Pump delivers a rated flow of 18 GPM at up to 2,700 RPM, with a maximum pressure rating of 3,000 PSI. The 12 ring size and 13-tooth SAE B splined shaft make this unit compatible with standard SAE B 2-bolt mounting flanges, and the inlet port is in-line with the outlet for straightforward circuit routing.

Built by Eaton Vickers, this single vane pump features Buna-N seals and SAE 4-bolt flange ports, 1-1/2" inlet and 1" outlet, suited for demanding applications including metal cutting machinery, plastic injection molding, dump trucks, and wheel loaders. Clockwise rotation is standard. The design supports outstanding volumetric efficiency and extended service life under sustained load conditions.

Question by: Lee S on Mar 21, 2026, 9:17 AM
got a 25VQ12A-11C20 pump to replace, is this the same one with the splined shaft and clockwise rotation?
Answer by: Customer Support on Mar 23, 2026, 6:40 AM
Match it up by the identifiers and the key fit points. This pump is model 25VQ12A-11C20 in the 25VQ series, with a 12 ring size, 13 tooth SAE B splined shaft, and CW rotation.
Question by: Dwayne F on Mar 5, 2026, 8:19 PM
runs at 2700 RPM rated speed -- is that enough for a dump truck PTO setup or do I need something with more headroom?
Answer by: Customer Support on Mar 6, 2026, 9:27 PM
For dump truck applications, 2700 RPM is a solid working speed for this pump. The 25VQ series is actually listed for dump truck use, and at 18 GPM rated flow with a 3000 PSI pressure rating, it handles the kind of hydraulic demand those systems put out. Just make sure your PTO output speed stays within that 2700 RPM ceiling and you won't be pushing it past its limits.
