PE55 Series Single-Phase 2-Speed Pump, Motor, Remote On-Off Motor Control (115VAC), 10 ft, Valve, Pump on, manually shift valve to pull, to hold (pump off), to release (pump on)

At full pressure the flow drops to 56 in³/min. That's pretty typical for a two-speed pump like this since it shifts to high pressure at the cost of volume. For reference it runs 440 in³/min at 700 PSI and 74 in³/min at 5,000 PSI so the curve falls off gradually as you climb. The true unloading valve helps it hold efficiency better at max pressure than a standard setup would.

Designed for heavy construction and concrete stressing, this pump is a good fit for jobs requiring high pressure and controlled release.

For heavy construction and concrete stressing work, it tops out at 10,000 PSI. Flow is 704 in³/min at 0 PSI, then it tapers as pressure rises, down to 56 in³/min at 10,000 PSI.
