runs at 2500 RPM rated speed, but what kind of flow am I actually gonna see out of this thing at that speed?
Question by: Kurt L on Nov 19, 2025, 3:45 PM
At the rated speed of 2500 RPM, this pump is spec'd for 28.5 GPM. That's based on the 19 ring size and the 3.74 cubic inch displacement. Real-world flow can vary some depending on system pressure and line losses, but 28.5 GPM is what the pump is built to deliver under rated conditions.
