runs at 2000 RPM, but what's the max pressure this pump can handle before things start going sideways?
Question by: Ray F on May 12, 2025, 9:40 AM
Rated at 2000 PSI maximum, so it's got solid headroom for most industrial hydraulic circuits running in that range. The displacement comes in at 5.5 cubic inches per revolution, and rated flow sits at 42.85 GPM. Keep your system pressure at or below that 2000 PSI ceiling and you're operating within spec.

What kind of fluid should I be using in this pump?
Question by: Peggy S on Nov 19, 2025, 9:28 AM
While the specific fluid isn't listed, this 30VQ series vane pump is generally used with hydraulic oils that meet the system's viscosity and temperature requirements. Always consult your equipment's manual for the right type.
