Question by: Duane F on Sep 3, 2025, 12:15 PM
pump puts out 65 GPM, but what speed does it need to be running at to actually hit that number?
Answer by: Customer Support on Sep 4, 2025, 9:48 PM
Rated flow of 65.92 GPM is based on a shaft speed of 2200 RPM, so that's the operating speed you'd need to be at to see that output. If your drive is running slower, you'll see a proportional drop in flow. Worth making sure your power unit or PTO is dialed in to that speed before expecting full output.

got a setup that needs clockwise rotation. is this pump actually CW and what shaft does it take
Answer by: Customer Support on Nov 22, 2025, 6:45 AM
For rotation and drive details, this unit is clockwise (CW) and it uses a 1-1/2 inch straight keyed shaft.

reckon this'll bolt right up to a standard SAE C flange?
Answer by: Customer Support on Feb 14, 2026, 4:56 PM
This pump features a 2-bolt SAE C mounting flange, so it should indeed bolt up as expected to any standard SAE C flange.
