WOJET Triplex Plunger Pressure Washer Pump, 3600PSI 2.7GPM, 3/4" Shaft, Self-Priming, Horizontal Replacement Pump Kit for Honda GX160 GX190 GX200, Dewalt 3000PSI, Simpson 90037, Generac 5-7HP Engines

Replaced bad pump on my pressure washer with this pump. Pumps that come on most homeowner pressure washers are junk that wear out in no time leaving you with a useless washer with a perfectly good motor. More expensive than other replacement pumps but should last much longer being a triplex pump. Easy to install and has better pressure than the old pump ever had

Excellent pump. It is very hard to find a pump with the inlet and out ports facing different directions. 👍👍👎

The real deal!! had to go to ace hardware and get smaller nuts for my pressure washer (generac $4bucks) so worth it money wise. Works well with my machine it is back to life will highly recommend. It is heavier compared to the one I switched out. Materials looks and feels very durable the installation was straight forward. The fit is perfect and I get great pressure

Did my first house wash today using this pump and I have to say that I couldn’t be happier with it. Smooth pressure the whole time. 10/10 would recommend this product. Mine is step up on a 7hp bilt-hard engine.

I can report that this pump will perfectly fit a popular clone of the Honda GX200. I believe I now officially have a Frankenstein pressure washer. It began life many years ago as a Troy-Bilt powered by a 5HP Honda. I replaced the worn out engine with a popular clone. The wet-end of the pump has been rebuilt a few times and now the bearings are making their presence known. This Wojet light commercial grade triplex represents a step up from the residential grade pump that my unit came with. I would consider it a half step between the residential grade box store pumps and the high end commercial grade pumps. As I work with high pressure and ultra-high pressure pumps for a living, I was pleasantly surprised at the build quality of this pump for the purchase price. While it’s not on par with a high end triplex, it is also not priced as one and represents a fair amount of value for the money. I run pressure gauges on any pump that I operate; first as a safety consideration and secondly to monitor performance, nozzle wear and assist in troubleshooting. Out of the box, this pump is running 2,400psi dead-heading. This is no surprise as most pumps are tuned down out of the box. As it is rated for 3,600psi, with a quality gauge, the pressure may be adjusted on the unloader valve. The adjustment is located under the tall black knob looking cap on top of the pump. You cannot simply turn the black knob to adjust pressure as wrongly advertised. Under the cap, you will find a locknut and a socket set screw to adjust pressure. I included a picture of these parts. Unlock the jam nut and adjust by turning the socket head screw with an Allen wrench. Turn clockwise increases and counterclockwise to decrease. Always adjust with the jetlance off and the pump dead-heading. Never adjust pressure with the jetlance operating. Doing so can cause the pump to over pressure when the jetlance is shut off. I’m not understanding all the hype regarding the cooling protection features of this pump as if it’s something special. It’s function and components are no different than any other modern day triplex high pressure pump. It incorporates an unloader valve, having a pressure adjustment as most all do, with a secondary function that diverts water into an internal loop when it is not going out of the jetlance, commonly known in the high pressure pump world as internal compensation, and dead-heading. When the pressure washer is in use and water is flowing through the pump and out the jetlance, any heat buildup is carried out with the high pressure water and the pumps is bathed in cool intake water. However, when in the internal comp mode, water coming from the high pressure side of the pump is diverted back into the inlet, circulating in a loop. Contrary to the advertisement claims, water constantly circulating in this internal loop builds heat over time due to friction and lack of incoming cooler water. The pump incorporates a thermal relief valve that senses the rise in water temperature, opens and allows the hot water to dump, allowing the pump to take in cooler water from the inlet in its place. Note the black thermal relief valve in the pic of pump components. Note that the old pump you’re replacing has the same components. They may look slightly different, but serve the same function. Aside from the few misleading claims, this pump is a great improvement over the general household models that come with most pressure washers sold at the big box stores and other outlets. It’s claimed to be a light commercial duty and I would agree with that statement. I believe it represents value and would expect it to provide good service for many hours of use. As with anything mechanical, it will require service at some point, and I’m curious to know if there is a basic rebuild kit available to repair the pump, that would include consumable parts like seals, check valves, plungers and O-rings.
