PJRW and PSRW are comprised of a P–9000 pump and a drive motor, and must be turned on and off by the user, usually with a foot switch or a toggle switch located near the pump. The most common application is for high pressure anchor washdown. No controls, plumbing or dry running protection is included, thus these are the responsibility of the user. See flow chart for P-9000 performance.

PSRO are comprised of a P–9000–1 pump and a drive motor that includes a reversing switch to change the direction of flow. Oil change and fuel transfer are the most common applications. No plumbing or dry running protection is included, thus these are the responsibility of the user. Performance may be calculated from P-9000 Performance With Water graph; P–9000–1 GPM flow will be approximately 75% of P–9000 flow while 50% greater PSI pressure may be achieved.
