Question by: Patty P on May 25, 2025, 9:22 AM
runs at 2500 RPM rated speed, but most of my application sits closer to 1800 to 2000 RPM. that gonna hurt flow output any?
Answer by: Customer Support on May 26, 2025, 1:42 PM
At lower speeds you will see a modest drop in flow relative to the 31.5 GPM rated output, which is measured at the 2500 RPM rating. For steady operation in the 1800 to 2000 RPM range that is a normal and acceptable way to run this pump. Volumetric efficiency on the VQ series holds up well across a broad speed window, so you are not losing efficiency in a dramatic way, just proportionally less flow than peak. If your system circuit was sized around that rated flow number, worth factoring the speed difference into your calculations before finalizing the setup.
