Question by: Steve P on Aug 27, 2025, 11:32 AM

Running a small hydraulic press setup and need to know if this pump can keep up at continuous high speed. What's the rated flow and max RPM on this thing?

Answer by: Customer Support on Aug 29, 2025, 6:18 AM

At 2000 RPM, this pump puts out 42.85 GPM and holds up to 2000 PSI. Those numbers line up well with small press and industrial unit applications, which is exactly what this series is built around. Vane pump designs like this one tend to hold volumetric efficiency well across a range of speeds, so you're not going to see a big drop-off as demand fluctuates.

Question by: Billy E on Apr 4, 2025, 6:40 PM

What kinda machine is this pump typically used on?

Answer by: Customer Support on Apr 6, 2025, 6:49 AM

These 30VQ series vane pumps are often found on power steering systems, smaller industrial units, and small press applications.
