Product Questions & Answers

pump's rated at 2500 RPM -- is that the max continuous speed or just a peak number they throw on the spec sheet?
Question by: Lee E on Feb 15, 2026, 8:53 PM
At 2500 RPM, you're looking at the rated operating speed for this pump, not a burst or peak figure. Running right at that number continuously is within what the pump is built for. Back it off some if your application sees a lot of heat or load cycling, and you'll get more life out of it. The 3000 PSI max pressure rating holds at that speed, so the two specs work together rather than independently.
