Question by: Vince M on Dec 9, 2025, 8:56 AM
got a setup that needs a 2-bolt SAE C mount and big flange ports. is this pump actually set up that way
Answer by: Customer Support on Dec 11, 2025, 8:15 AM
It uses a 2-bolt SAE C mounting flange and SAE 4-bolt flange ports with a 3 inch inlet and a 1-1/2 inch outlet.
Question by: Floyd P on Jul 16, 2025, 6:53 AM
pump puts out 77 GPM at what speed exactly, and is that at full 2500 PSI or just free flow?
Answer by: Customer Support on Jul 18, 2025, 6:55 AM
Rated flow for this unit is 77.14 GPM and that figure is tied to the 2200 RPM speed rating. The 2500 PSI maximum pressure rating is a separate spec reflecting the pressure ceiling the pump is built to handle. Both numbers come from the same pump running at its rated conditions, so you're looking at a unit that can move serious volume while holding up under high-pressure demand.
