Product Questions & Answers (1)

Question by: Roy R on Jul 25, 2025, 12:54 PM

pump's rated at 2500 RPM -- is that the max I should be running it, or is there some headroom above that?

Answer by: Customer Support on Jul 26, 2025, 6:31 PM

2500 RPM is the rated speed ceiling for this unit, so you'd want to treat that as your operating limit rather than a target you push past. Running consistently at or near the top of a pump's speed rating tends to shorten seal life and affect volumetric efficiency over time. For most applications this pump was built for, like dump trucks or wheel loaders, staying at or below that threshold keeps things running clean.
