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

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

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!

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.

Very surprised with the quality of this unit, i buy a few larger brand pumps a year and this seems to be made as well and better than some.

Bolted right up to the motor. This thing has plenty of pressure. If I try and crank up the pressure to the max it will bog the motor. So I simply backed it off a little. My only complaint is after a few minutes of use, it will get air pockets and I almost have to prime it again, turning off the motor and pulling the trigger of the wand for a second and then starting it again. After doing this once it will work flawlessly until I’m done using it. Overall good value for the price considering the cost of the original pump.

Great triplex pump upgrade from the axial pump off my simpson. Works perfectly and easy to install and use.

works good, a little bit of a struggle to fit, but got it on there, have been doing lots of work for 6 months now and it has kept working.

fits like a charm

Works good, no issues with it. Powered by a 212 predator does the trick for a budget build. The adjustable regulator is really nice too for sensitive areas and weak paint
