Product Questions & Answers

got a setup that needs clockwise rotation and the outlet on the opposite side. is that how this 25VQ is built
Question by: Harvey R on Feb 6, 2026, 6:38 PM
For orientation, this model is a CW rotation pump with the port location listed as opposite outlet, so it matches a clockwise drive and that opposite outlet layout.

Running a dump truck operation and need to know if this pump can hold up at full pressure continuous, what's the max PSI this thing's rated for?
Question by: Wade P on Jun 12, 2025, 8:21 PM
Rated at 3000 PSI maximum, this pump is built with high-pressure, high-speed applications in mind, so dump truck use falls squarely in its intended range. The 25VQ series was specifically called out for dump truck applications, and with a speed rating up to 2500 RPM alongside that pressure ceiling, it handles demanding duty without being pushed outside its design envelope.
