AAA 4400 psi pump

3 months ago
I bought this to replace my pump on my Simpson pressure washer. Bolt pattern was perfect. Install took 10 minutes. I’ve used 5-6 times since the swap out. Pressure is like brand new. I was getting 5000 psi at the gun. Had to lower the psi adjustment back to 4400. Pleased with purchase

Yes, I recommend this product.

Pump Sucks!

9 months ago
These pumps suck! I've gone through 3 in 30 days. The seals fail, the lube oil turns into an emulsion, then the shaft disintegrates.

No, I do not recommend this product.
