Additional Notes & Service Information

The 510003 Pressure Washer pump kit is not designed for gravity-fed systems, and an on-demand water pump is always recommended to consistently supply water to the pump at 20-60 PSI of inlet pressure.

Service Note:

The "Burst Pressure" of a pressure washer pump is the highest pressure the pump produces when in a static position and when the trigger is first squeezed, giving the initial burst of pressure and does not reflect the actual operating pressure.

The accurate operating PSI of any pump would be determined by the engine’s horsepower and the size of the nozzle being used at the end of the wand, which restricts water flow and causes back pressure.

Adjusting factors such as engine RPMs, nozzle size, or engine horsepower can allow a single pump to be rated at various GPM and maximum PSI levels.
