Features & Details
- High-Efficiency Cleaning Power: Our pressure washer pump delivers up to 4400 PSI of powerful water pressure with a maximum flow rate of 4.4 GPM, ensuring fast completion of tasks ranging from household cleaning to light industrial jobs. (Recommended working pressure: 4000 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.

Fits good on a John Deere 3800 pressure washer. Can't use the pump at full capacity. It is stronger than the motor.

Ive had my Simpson Psi washer from tractor supply from several years. Im on my third AAA 4,000 psi pump. Granted I don't use the washer much I only get about a year may be two before the pump goes out. I had no idea Vevor made PSI washer pumps. While on the vevor site buying other things I seen the 4,400 pump for 1/2 the price of the AAA, which don't last. I bought the pump and right out of the box I noticed a big difference in size & weight. I bolted it up to the Honda GX 270 motor & man this thing puts out the psi. I had to turn the pressure down so the little Honda could run it with out stalling down. So far I love it but time will tell how long it last. if it last as long as the higher priced AAA pumps I will mark it down as a win.

Extremely robust great performing pump I am running it on a Honda gx240 engine at the moment and the pump is more than that engine can put out but never the less with that engine a 100’ hose and a 5.5k turbo nozzle it still cuts through dirt and grime cleans concrete white again just a little slower. If mounted to a gx390 or equivalent it would be an absolute animal. But I am still thoroughly impressed and happy with this pump in the configuration I have it in I would totally recommend and buy it again my only recommendation if putting together your own pressure washer start our with a gx390 sized engine to get all the performance out of the pump a 240/ 270 engine will work and work pretty darn good your just leaving power on the table, with all that said this pump is freaking awesome 10 out of 10 would recommend and would buy again

The pump was delivered a few days later than promised, but the packaging was excellent.
We replaced our Harbor Fright 4400psi/4.4gpm pump with this one and could tell immediately that the pressure was better than the original pump.
We hope that the pump will provide the 500hrs it's advertised for, and continues to perform as well as it does now for the life of this pump.
Good job Vevor, thanks to you, my 4400psi pressure washer is a beast again!

Very good pump so far. Direct replacement for a leaking axial cam pump on a 6 HP B&S engine. Easy bolt on and go. Smooth consistent pressure. Engine doesn't seem to work as hard as with the previous pump, but the pressure is just as good or better.
