Not sure if it fits your model? We’ll check for you if you send us your brand, model number, PSI, and GPM! 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 supplies the force needed to easily rinse a two-story house, remove oil stains and deep-seated grime from driveways, clean large equipment, and prepare large surfaces for painting. This is how you get your machine back to its original state and extend its lifespan.
INTEGRATED UNLOADER: The power washer pump’s primary safeguard against damage and overheating is the integrated unloader valve. The valve immediately opens to relieve pressure when you release the trigger. Water entering the manifold does not stall; rather, it flows continuously through it, removing 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 MORE FLEXIBILITY: This model, in contrast to the majority of pumps, has a unique self-priming feature that allows you 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 has an adjustable unloader knob, a brass pump head with polished ceramic pistons that resist corrosion, a forged brass manifold, and a blue aluminum crankcase that has been powder-coated. 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 are confident in its performance. We will address any issues you encounter.
