Product Questions & Answers

If I'm running this thing at max pressure, how loud is it gonna be?

Question by: Darryl F on Sep 25, 2025, 6:36 AM

These DuraForce pumps use what they call an SPU design. That cuts the pressure pulses way down – by about 70% – so it should run quieter than you might expect at that pressure.
