Easy Installation

Quick and hassle-free installation is a key feature of this pressure washer pump. The package includes mounting bolts, a shaft key, 5 color tips, a 3/8" plug, and a m22-14mm male adapter. Pre-sealed, this pump can get your pressure washer back to life within 10 minutes. The pump features a threaded 3/8" socket pressure washer hose outlet and a 3/4'' NH garden hose inlet. The standard bolt pattern fits most horizontal 1" shaft gas-powered pressure washers, with the exception of non-1" shaft horizontal engines.

Adjustable Unloader Valve

Easily adjust the pressure by twisting the unloader valve. No need for a wrench, making the cleaning process simpler and more professional. Adjusting the unloader valve prevents uncontrolled high pressure, which can cause damage to cleaning objects.

Easy Oil Change

Change oil easily through the oil inlet. Just check the oil level using the power washer pump's sight glass without needing an oil dipstick. With clear visibility to the oil level and the oil itself, you can quickly identify when levels are low or if water has contaminated the oil.
