How the Pump Works

The RMW22G24-EZ utilizes a proven axial cam design, which translates rotational power from the engine into high-pressure water flow efficiently and reliably. The EZ Start system prevents high pressure from building when the trigger gun is in the closed position at startup, dramatically reducing the engine pull force and improving ease of use.

The adjustable unloader valve allows users to match spray pressure to each cleaning task, providing flexibility for various surfaces and dirt conditions. The built-in chemical injector draws detergent into the water stream, improving the pump’s cleaning power for oil, stains, and tough grime. Meanwhile, the crankcase is permanently lubricated with premium synthetic oil, eliminating the need for oil changes and lowering lifetime maintenance costs.

Constructed with ceramic plungers for heat resistance, stainless-steel valves for corrosion reduction, and heavy-duty seals for leak protection, this pump is built to provide smooth operation and dependable performance over time.
