(Recommended working pressure: 3100 PSI for typical residential and light industrial cleaning and to extend pump life.)
  • Durable, Long-Lasting Design: Utilizing advanced anodizing technology, the parts washer pump’s surface forms a hard protective layer, significantly enhancing corrosion resistance and durability. Built to last, this pump provides reliable performance for up to 500 hours of continuous use.
  • Equipped with Pressure Regulator: Adjust pressure output precisely based on engine operation to achieve optimal performance for any cleaning task. Easily reduce pressure during short pauses to switch the engine to idle mode, reducing noise and extending equipment life for a more comfortable operating experience.
  • Broad Compatibility: Featuring a standard SAE bolt pattern, this power washer pump is compatible with various horizontal engine pressure washers, including Simpson MorFlex models 40224, 40225, 40226, and Santoprene model 41182. Match engine orientation, PSI, GPM, engine shaft diameter, and current pump inlet/outlet connections to ensure compatibility.
  • Easy Maintenance: An integrated oil sight glass lets you check oil levels without disassembling the unit, helping detect low oil or contamination promptly to keep the pump in peak condition. To extend lifespan and ensure continuous efficiency, we recommend changing the oil every 60 hours of operation. Note: This replacement pump for power washer is intended for use with cold water only.

3600psi pump replacement
Easy fix, super powerful! Great quality for the money. The new pump I received had a new bolt design that was really easy to attach. Pump came with a new nice oil plug too.

The pump broke within 5 minutes of owning it.
The quick connect where the pressure washer wand hose hooks up to broke withing 5 minutes of owning it. I reached out to VEVOR with the hopes of them sending a new one to replace the broken one. After a couple days they offered me a 30% refund of the original purchase price. I declined it saying I want a new pump to replace the broken one. After a few more days they offered 60% of the original price saying it was their final offer. I took the offer because the alternative would be $0. Extremely disappointed with their customer service. They say there's a warranty on their products, but clearly they will slither out of it when the time comes.

Works great with tons of pressure to spare. Difficult to adjust to match engine output. I can envision buying another one in the future.
