Customer Reviews for VEVOR Pressure Washer Pump, 25.4 mm Shaft Horizontal Triplex Plunger, 4400 PSI, 4 GPM, Replacement Power Washer Pumps Kit, Parts Washer Pump, Compatible with Simpson MorFlex Models 40224, 40225, 40226

This is a much less expensive 4400 PSI, 4 GPM power washer than the CAT Brand. But, so far, it seems to be doing the job. The pressure adjustment is very hard to turn by hand. I have to use a wrench to turn the adjustment. But this isn't a big deal if I don't intend to adjust the pressure very often. I haven't installed a pressure gauge yet to see if I do get the full advertised 4400 PSI. Hopefully, it will have or nearly have the capability to get the 4400 PSI. It installed easily on my GX340 Honda motor just as the old Cat Brand did.

Works great on my 13.5 HP engine! Some reviews have said it doesn’t put out the rated power. You have to pop off th red cap on the adjustment knob, comepletely remove the adjustment knob, loosen the set screw and tighting the locking nut down to gain more adjuatment. When I first installed it, I was topping out at 3,500 psi max. I changed that adjustment and now I can get well over 4,000 psi. I set it to just under 4,000 with the trigger pulled and it spikes to about 4,300 when I let off. I can’t speak on the reliability yet. I also plan to add a external unloader valve to keep it from overheating.

After having AAA triplex not honor their pump that lasted only 6 months - so far is much better pump at half the price - much much more powerful too -

I was losing pressure over the years with my OE pump. This fit right on with little effort. Took about an hour to remove the old pump and about 10 minutes to install this one. NOTE: My engine is only 9 HP, I had to turn the pressure valve down significantly in order for my engine from bogging heavily under load. However, I am getting enough pressure to reach my (over) 25 ft roof. I'm sure it will work even better for the 14hp engines it was intended for.

Excellent remplacement

Pressure washing driveway

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

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.

I was sick and tired of buying namebrand pumps and then costing twice as much money when guys blow them. This things lasted time will tel how long but def a good value
