OEM Technologies 3400 PSI 2.5 GPM Horizontal Pressure Washer Pump Kit 90029

This worked perfectly on my pressure washer. Honda GC 190 motor on a simpson frame. All parts included. Super easy install.

I am overwhelmed, this actually fix my almost new $900 pressure cleaner. The first owner got very frustrated and offhandedly, offered it to me for $130. It’s as new as can be, but the key that aligned the drive shaft on the motor to the pump wore down on the pump side. I took out 4 bolts and put the new pump on with a new key and what do you know. I have a brand new $900 pressure washer for $130 plus the $100 for the pump. How much happier could I be.

My Simpson pressure washer (3100 PSI, 2.5 GPM) has served me well over a number of years, but its water pressure had dropped to the point that made cleaning my driveway very difficult. After reviewing some Youtube videos, I saw that the pump could be replaced. This unit is an exact OEM replacment for my unit, and the new pump restored the original capability to clean. Some time after I originally purchased the washer, I bought a surface cleaner, but I could not get it to clean concrete surfaces with mold, mildew, stains, etc. After I replaced the pump, the surface cleaner works well, and this attachment really speeds up cleaning my driveway. The pump is fastened to the gasoline engine with four allen key metric bolts that were somewhat stuck, but a little leverage on the allen key loosened them. The rest of the replacement was easy. Note that there is an alternative, less expensive approach to pump replacement: Ebay sellers provide new seal and valve kits to allow rebuilding the original pump, but I didn't realize this until after I had replaced my pump. When I disassembled my pump to see why it failed, I found that the water seals were worn and the valves had worn out; so a seal kit + a valve kit for a total of about $60 would likely have restored the original pump.

Four stars since the new looks like it will be harder to rebuild if it goes down. Did not want to replace it but could not get any water thru the lines at a good presure.

It worked out with this pump it’s the correct & direct fit of what I needed & a good price VERY SATISFIED

Worked for 20 minutes, then stopped working. Something to do with valving; pressure builds up to the point the engine stalls. To late to return and it'll be interesting to see how they handle the warranty

Bought it as a temporary replacement for my Dewalt 3100 Power washer while waiting for back ordered repair parts. When I opened the box and saw how small it was compared to my own pump (about 1/3 the size) I wanted to send it back because I figured it couldn't be very powerful.....But unknown to me ..It is a non returnable item. Even if it was never used. Amazon refused to do a return. Figured ...as long as I was "stuck" with it..I would bolt it on and see what it can do. Installation takes only 5 minutes. I was surprised at how well it worked. Good power for a small unit. Ran it for an hour with no problem. I am still going to put my old pump back on once it is repaired..But I would recommend this pump to anyone needing a replacement

This pump worked out great for a replacement on my pressure washer. This one has a little more power then the last pump and the cost wasn't bad at all. Fit like a glove and didn't have to make any adjustments at all.

Good packaging, minimal documentation. Was easy to replace the old one, and worked great out of the box. Good value.
