    Feature:

    Our parts washer pump features a standard SAE bolt pattern for easy installation. It is suitable for various gas pressure washers with horizontal engines

    The power washer pump strengthens plunger hardness to reduce the chance of being damaged by impurities. It also improves wear resistance and prolongs the life of water/oil seals.

    Our replacement power washer pump has a sight glass for easy oil level inspection. By observing the oil level and the oil itself, you can easily check the oil level or see if water has mixed into the oil.

    From outdoor walls, sidewalks, cars, to construction sites, our power washer replacement pump can get the job done efficiently and effectively. It's the go-to tool for all your cleaning needs.

    Pump out the Competition: Looking for a high-performance pressure washer pump? With 4400 PSI max pressure and 4 GPM max flow rate, it's perfect for daily cleaning tasks such as walls, sidewalks, and vehicles. Save money by replacing your pump instead of buying a whole new power washer.

    Wide Compatibility: Designed with a standard SAE bolt pattern, our parts washer pump is compatible with various gas pressure washers with horizontal engines, including Simpson MorFlex models 40224, 40225, 40226, and Santoprene model 41182. To ensure compatibility, be sure to match engine orientation, PSI, GPM, engine shaft diameter, and current pump inlet and outlet connection.

    High-Pressure Resistant Structure: Say goodbye to impurities damaging your plunger! Our power washer pump strengthens plunger hardness to improve wear resistance and prolong the life of water/oil seals. The one-piece pump head made of forged brass material offers a better sealing effect, high strength, and increased durability.

    Easy Oil Level Inspection: Checking the oil level has never been easier with our replacement power washer pump's sight glass and advanced oil seal technology – no need to use an oil dipstick. With visibility to the oil level and the oil itself, you can easily see when oil levels are low or if water has clouded the oil.

    Use It Anywhere: Whether you're cleaning outdoor walls, sidewalks, cars, or construction sites, our power washer replacement pump is the perfect solution to boost water pressure. It is a great helper for both daily and professional cleaning tasks.
