Product Questions & Answers

got a 25VQ21A-11B20-L pump in here now, is this the same one with the CCW rotation and the SAE B splined shaft?
Question by: Joyce M on Jan 27, 2026, 7:03 PM
Match-up wise, it lines up with model number 25VQ21A-11B20-L, CCW rotation, and a 13 tooth SAE B splined shaft in the 25VQ series with the 21 ring size.
Answer by: Customer Support on Jan 29, 2026, 8:18 AM
pump puts out 31.5 GPM at what speed, and is that at full 3000 PSI or just rated flow conditions?
Question by: Travis W on Sep 12, 2025, 10:16 AM
Rated flow of 31.5 GPM is at the 2500 RPM speed rating for this pump. The maximum pressure is 3000 PSI, so that flow figure and that pressure ceiling are both part of the same operating spec. Running it right at the pressure limit continuously is a different conversation than hitting peak flow, but both numbers come from the same design envelope on this unit.
