How the Pump Works

The SRMW22G28-EZ-SX utilizes an advanced axial cam design to efficiently convert engine power into high-pressure water flow. As the crankshaft rotates, reinforced pistons pressurize water through stainless steel valves, delivering consistent spray pressure at the wand.

The EZ Start system is a standout feature, eliminating static back pressure that typically resists engine pull-starts. This ensures faster, smoother startups and less strain on your equipment. Additionally, the integrated unloader valve safely regulates system pressure, while the factory-installed thermal relief valve automatically protects the pump from overheating when water is recirculating in bypass mode.

For enhanced cleaning, the built-in soap injection system allows you to easily apply detergents directly through the pump, increasing efficiency when tackling grease, mold, and stubborn dirt.

Benefits of the SRMW22G28-EZ-SX

• Durable Build: Reinforced SRMW housing and internal components withstand high pressure and extended use.
