  • RESTORE PEAK POWER: Breathe new life into your washer. Engineered for heavy-duty use, this 4400 PSI, 4.0 GPM water pump for pressure washer restores full power and enhances reliability. It provides the force to blast away deep-seated grime and oil stains from driveways, the pressure to rinse a two-story house with ease, and consistent flow for cleaning large equipment and prepping big surfaces for painting. This is how you regain your machine to original power and extend its service life.
  • INTEGRATED UNLOADER: This integrated unloader valve is the power washer pump’s main defense against overheating and damage. When you release the trigger, the valve instantly opens to relieve pressure. Instead of stalling, incoming water flows continuously through the manifold, carrying away heat. Unlike older designs where water stops and temperatures soar, our system provides constant cooling. This “cool-down cycle” reduces thermal stress, protects critical components, and extends pump life.
  • SELF-PRIMING FOR GREATER FLEXIBILITY: Unlike most pumps, this model includes a unique self-priming function, giving you the freedom to draw water from a variety of sources. Whether it’s a bucket, pool, or tank, this replacement pressure washer pump happily pulls water, making it ideal for areas without a direct faucet connection. Perfect for mobile tasks or jobs at construction sites, its versatility ensures you can tackle tough jobs in remote locations or expansive outdoor spaces.
  • THE LONG-LASTING PRESSURE WASHER PUMP: Engineered for longevity and performance, it features an adjustable unloader knob, corrosion-resistant brass pump head with polished ceramic pistons, forged brass manifold, and powder-coated blue aluminum crankcase. Pre-sealed and oil-filled for easy maintenance, it connects via 3/8" quick-connect outlet and 3/4" garden hose inlet. Includes siphon tube, mounting bolts, and shaft key. We stand behind its performance. If you run into issues, we’ll fix it.
  • DIRECT ENGINE CRANKSHAFT MOUNT ONLY:This pump is built to mount directly onto the engine crankshaft. No other mounting configurations or adapters are compatible.
