Product Questions & Answers (1)

Question by: Daryl M on Jun 20, 2025, 11:58 AM

pump's rated at 2500 RPM max -- does that mean it'll hold up runnin closer to that top end, or is it better to keep it pulled back some?

Answer by: Customer Support on Jun 22, 2025, 8:33 AM

At 2500 RPM you're at the rated ceiling, not a comfortable cruising speed. For continuous duty cycles, keeping operating speed noticeably below that ceiling reduces wear on the vanes and ring over time. The 3000 PSI max pressure rating gives you headroom on the pressure side, but RPM is where you want to leave yourself some margin if the pump is running most of the shift.
