Question by: Denise R on Mar 24, 2026, 2:01 PM

Running a small hydraulic press setup and need to know if this pump'll handle continuous duty at full pressure or if it's more of an intermittent-use unit.

Answer by: Customer Support on Mar 26, 2026, 6:42 AM

At 2000 PSI max pressure and a 2000 RPM speed rating, this pump is built for high-pressure, high-speed applications, but the product data classifies it for use in small press and small industrial unit applications. That puts it squarely in the kind of moderate-duty hydraulic work where it performs reliably, not heavy continuous industrial cycling. For a small press running regular production cycles, it fits well within its intended use case.

Question by: Howard M on May 12, 2025, 7:21 AM

Will this work for power steering?

Answer by: Customer Support on May 14, 2025, 8:12 AM

This Eaton Vickers VQ series vane pump is applicable to power steering, industrial small units, and small press applications.

Question by: Curt A on Jul 28, 2025, 8:27 AM

got a power steering setup on a small unit, would this 30VQ pump be the right kind or is it more for industrial stuff?

Answer by: Customer Support on Jul 30, 2025, 8:02 AM

For typical use, it fits both worlds. The 30VQ series is commonly used in power steering, and it also shows up in small industrial units and small press applications.
