Product Questions & Answers

got a setup that needs counterclockwise rotation. is this pump actually CCW, and how’s the inlet and outlet laid out?
Question by: Tommy J on Jul 18, 2025, 12:01 PM
Rotation is counterclockwise (CCW) on this 25VQ pump, and it uses an outlet-opposite-inlet port layout. Porting is SAE 4-bolt flange with a 1-1/2 inch inlet and a 1 inch outlet.

Will this Eaton Vickers pump work on my dump truck?
Question by: Eddie M on May 25, 2025, 6:03 AM
This 25VQ series vane pump is listed as being suitable for dump truck applications. It's also used in oil and gas, metal cutting, wheel loaders, and plastic injection molding.

Running a wheel loader that needs a CCW pump with a 2500 RPM limit, does this one fit that bill, and what kind of flow am I looking at?
Question by: Joyce H on Aug 13, 2025, 6:37 PM
For counterclockwise rotation at up to 2500 RPM, this pump lines right up with that requirement. Rated flow comes in at 31.5 GPM, and it'll handle pressures up to 3000 PSI. The 21 ring size puts it in a solid mid-range displacement at 4.12, so it's got enough output for loader hydraulics without being oversized for the application.
