Question by: Jimmy M on May 17, 2025, 8:02 AM

How much flow can I expect from this motor and pump at 1000 PSI?

Answer by: Customer Support on May 18, 2025, 6:39 PM

At 1000 PSI, this motor and pump assembly delivers approximately 1.55 gallons per minute. This performance is part of its standard duty operation, ensuring reliable flow within its specified pressure range.

Question by: Clint M on Sep 15, 2025, 8:33 AM

What kind of flow rate can I expect from this pump at different pressures?

Answer by: Customer Support on Sep 17, 2025, 6:26 AM

Flow rate varies with system pressure on this unit. At 500 PSI you'll get 2.10 GPM, but as pressure increases the flow drops off. At maximum 2000 PSI it puts out 1.00 GPM. Most applications fall somewhere between those two points depending on your hydraulic load.

Question by: Rick H on Apr 23, 2025, 7:31 AM

reckon this pump's flow changes with pressure? like from low to high end

Answer by: Customer Support on Apr 25, 2025, 6:54 AM

It puts out 2.10 gallons per minute when you're at 500 PSI, but that drops down to 1.00 GPM once you hit 2000 PSI.
