AAA 90037 Horizontal Triplex Plunger Replacement Pressure Washer Pump Kit, 3700 PSI, 2.5 GPM, 3/4" Shaft, Includes Hardware and Siphon Tube, for Industrial Gas Powered Machines, Black

easy change out and pressure washer works like new again.

Got my simpson pressure washer up and running. Does not come with pressure washer pump oil. So make sure you get some of that as well. Also there is a small bag with mounting bolts and a new shaft key in the box that I didnt immediatly see as it was under some packing material. So make sure you dig that out before you throw the box away.

This pressure washer pump works perfectly on my pressure washer I went from 3000 PSI to 4000 PSI I would buy from them again if ever I need to I know of three people that have already bought the same pump for their pressure washers and they love it also

I bought few years ago and still works fine forme

Replaced pump on a Honda engine power washer. Working great. Very easy to install once you get the old pump off.

Bought this pump replacement for my Dewalt pressure washer. Replacement was simple. Used it very infrequently and for basic homeowner tasks. One day I went to use it to wash off the driveway from mulch and topsoil residue and just after beginning to use it I heard a loud pop sound. Pressure dropped and water was spraying out of the area where the hose connects to the pump. At first I though I blew a hole in the hose but later I realized the brass housing itself split. There is no other explanation than it was a bad casting of the brass. It simply should not do this. So now I’m faced with spending another 319.00 for a replacement. On top of that, because of where the split happened ( right at the hose attachment point) my house is permanent stuck in the fitting. Mind you this hose is literally weeksOld because my old one did blow out from use and sitting in my barn in between uses. So I’m also forced to buy a new hose as well.Just very frustrated and disappointed with this Amazon product.

For my pressure washer perfect. Quick 20 minutes job. It comes pre filled with pump oil. Just don't forget to remove the red tab on the oil cap... And yes a very small amount of oil may come out of the tiny hole in the cap. It to allow the oil vent if needed.

First of all, this pump arrived less that 12 hours after I ordered it. My old pump blew the seals one afternoon, and I ordered this during dinner that night. (yes I could rebuild the old pump, and I eventually will, but I needed to be up and running ASAP.) It took less than 15 minutes the next morning to swap out the old pump on a DeWalt 3400 gas powered pressure washer.And while I can't explain it, the engine is much quieter with this pump installed, though the pump pressure at the nozzle seems to be equally strong. All in all very happy.Only complaint is the advertised "5 Year Warranty" does not include valves or seals. If the pump housing cracks, I guess they'll replace it. For anything else, you're on your own.
