Product Questions & Answers

runs up to 2500 RPM on this thing -- is that enough for metal cutting equipment or do most setups in that industry need something faster?
Question by: Steve C on Jul 17, 2025, 2:15 PM
For metal cutting applications, 2500 RPM is right in the range you'd expect from a vane pump doing that kind of work. The 25VQ series was built specifically with metal cutting as a target application, so the speed rating lines up with what those systems typically demand. Pair that with a 3000 PSI max pressure ceiling and a rated flow of 31.5, and you've got enough muscle for most production-grade cutting setups without pushing the pump past its limits.

Will this pump work okay for plastic injection molding, or is it too much pump?
Question by: Dale F on Dec 2, 2025, 7:00 AM
This 25VQ series vane pump is definitely suitable for plastic injection molding applications. It's also good for metal cutting and oil & gas, which are all pretty demanding uses.
