Customer Reviews for VEVOR Pressure Washer Pump 1" Shaft Horizontal Triplex Plunger 4000 PSI 4.0GPM

I v been using it for a year now Pressure washing engine s before I work on them Quality is legit Price is great I'd buy it again

Perfect match to DEWALT 4 gpm/ 4200psi. Replaced my AAA pump.

Seems to be a good quality product. However, when opening the box, the pressure control valve appears to be damaged. Sent a message to seller.

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

Fantastic pump. Easy to install. Even came with oil in it.

Pump seems to develop as much pressure as the original it replaced. So far it has been reliable and gets the job done. Great value!

My original pump had several leaks, and I replaced the pressure regulator assembly a few years ago. It was the original D____S OEM brand. Had many problems with this pump leaking because the threads on most of the components were very fine and could actually be stripped easily if tightened too much. The problem was, it would leak unless very tight. Go figure. This new pump looks to be built much better, and was less costly than just the parts for the old one. I had a tough time removing the old pump from the shaft because it was quite rusted. I had to take apart the front and back covers of the pump, and ended up using an air chisel with a blunt end to actually push the pump further onto the shaft slightly. Once I could tell it moved, I was able to pull the pump off. I wire brushed the engine shaft until it was like new, then greased it slightly. The new pump slid right on, I re-used the old bolts to fasten it, then installed the fill cap. Cleaned up the area, hooked up the water hoses, and I had pressure like never before. WOW! I had to hold onto the sprayer handle very firmly as the pressure of the water really pushed me back. The spray is not only powerful, but very even with each of the nozzles. I ordered the 4200/4.0 unit btw. This pump is awesome, much quieter, and although I have just started using it, I can tell it's built to last. Extremely happy I chose this pump, both for the cost and performance. It took me about 2hrs to remove the old pump, about 10 min to install the new one.

Wow it has power worth it ..it's my second pump I buy for my power wash. And for the price you can't I have bought hydraulic pump and wow

Assembly was fine. Start scews by hand and thread in as far as possible before attempting to snug them down with a curved allen wrench. I personally didnt have tool clearance issues as did other reviewers. If you want full pressure up near 3600 psi you will need to remove the red pressure adjuster handle then loosen the Allen set screw and screw the stop nut down all the way to the bottom. I thinknitbis factory pre set to allow only about 2700 PSI. So far is works good. There isn't a thermal relief valve so I wouldn't let the engine run greater than 30 seconds if you aren't actually spraying water. Haven't used for an extended period of time so not bsure on long term durability. I would recommend use of Stabil pump protector to lube the pump and prolong life of seals and valves after use or before storage.

My AR pump failed after about 15 years of use. The 3700 psi had gotten down to about 1800 psi before it finally let loose. I was looking at 600 to 800 dollars to replace the pump. After a month of debating I decided to give the Vevor pump a try for $156. It works great. I have a gauge installed and realized that my 11hp motor did not have the full power to run 4400 psi which is fine. I turned the pressure down to 3100 psi and it works great. At the price if I get 5 years out of the pump then I gor my money's worth. I mainly use it to wash school buses before I bring them in for inspections and other maintenance. I also use it at home since it belongs to me and not the company. I am happy with the performance only the pump. I did purchase some high quality pump oil and I am planning to do an oil change after the first couple hours of use. I might purchase a spare for the shelf since the price is so low. Again it is a great pump at a great price. I have only had it less than a week but have used it for 1.5 hours straight and it worked exactly as advertised.
