Some Tips to Choose the Right Replacment Pump to Bring Your Power Washer Back to Life:

<1>Match Your Engine Orientation:

Horizontal Engine: The pump is installed horizontally onto the engine. Vertical Engine: The pump is installed vertically below the engine.

<2>Match your machine's PSI And GPM.

<3>Match the Engine Shaft Diameter.

The shaft diameter for horizontal pumps is either 3/4 inches or 1 inch. (Please refer to the engine specifications to confirm.)

<4>Match Current Pump Outlet Connection.

This will ensure that your attachments are compatible with the new pump. (If the connection does not match, you may need to use adapters or modify the setup.)

The pump arrived on time and was very well packaged. Installation is easy and the pump comes complete with the oil installed. I've only used the pump for about an hour but it worked well and provided very good pressure.

I own a kitchen cleaning exhaust company so my machines get a lot of work everything work every single day well usually nights and I bought this DeWalt and a little triplets pump did it had you know started losing his pressure whatever so this was a killer still even with the shipping it was like blessed in 180 I believe like 169 or something and with tax and so that's not bad and I've had the thing going for a little bit over a month and a half and that's great for the the money if you see I have a lot of machines lannda $6k for 4,000 PSI mi T m not much cheaper in Hawaii let alone to get replacement parts just for a valve kit which is 160 bucks for a general pump that comes on these they want to charge me $120 for shipping for something that doesn't even weigh a pound and it's kind of ridiculous so I decided I was just going to use my Honda motor that I had with this one and all my other ones and buy these cheaper ones I need like $4,000 and for the bang I can get valve kits and switch them out but why I can just buy a brand new and set it on the side think it valve kits and have a whole bunch of them sitting because like I said I got my machines are getting used every single day for how many hours and a little bit hard I'm even using certain ones on my mi T m elctric warm water machines which are in Hawaii only from 1 dealer $3k or more they're cheaper in the mainland and even online but nobody wants to send stuff to Hawaii it's a bit painful so for my businesses as much as I go through this is it a solid buy for the solid money it does the job it has the PSI and a month and a half and it's still going it's worked every single day for that month and a half and I'm going to change oil this weekend and just keep it going and probably going to buy a second one next month just to have it sitting in case it goes out again and then I'll get the valve kits but good bang for your wallet and somebody like me who counts on things being a little bit lower cost if I was to use the one dealer and repair guys here because I if I didn't know how to do this we're talking about ridiculous overhead I mean so at the same time I'm always on my numbers for my overhead so that I can keep in the profit side for my business as we are a high overhead business and being the best in our industry here in Hawaii which is pretty crazy we have summer seasons and then at the same time we can be busy all the restaurants can be busy all year long so we do a lot of work you know and these machines I got to stand by them and especially these pumps that I replaced they are well worth the money they do the job and I can rely on them but any pump that gets as many miles as what my company does is going to fail and we'll see how long it is and maybe I'll update that have a good day aloha

The pump I purchased has a pressure adjuster that is defective. I tried to contact them with no success. In the inside of the adjuster there is a cap that is not tight. As it starts getting loose, the pressure increases more and more. To a point where the pressure spikes to 6,000psi or more and it blew off (broke in the middle) of my hose splitter. A piece of metal blew off somewhere down the street. I'm glad nobody was hurt. After the review, they contacted me and after a couple of days I received a full refund. I also learned that they do not carry my model anymore, they have new models that, I think, should be given a 2nd chance to prove they are better quality now.

I bought this pump 4.4gpm up to 4400psi as a replacement pump for my Honda GX340 11hp motor and it's very strong and works great. I previously tried the 3.8gpm up to 4000psi pump and they do look exactly the same but the 4.4gpm 4400 psi pump is a good bit more powerful and I am very satisfied with the price was a bit less as these have gone up in price recently but other than that very happy!

I don't usually write reviews, but this pump has been GREAT.. so far anyway.. I'll keep this short.. I bought this pump to replace a 15-20 year old pump on a Devilbiss pressure washer that finally gave up the ghost.. I needed a pump that was powerful, and one I could get fast, well this one fits those needs.. I'm using my pressure washer to strip as much old pant off the walls of my concrete pool. For the price of this pump I thought, who cares if it lasts, as long as I get the pool done. I can't say anything for longevity, but for a couple days in a row now I've used this pump on full power and non-stop. I've only stopped to give my hand a 30 second rest, move to another spot, or my power washer has run out of gas. I don't have a pressure gauge, but this pump is EXTREMELY POWERFUL. So far, I couldn't be more satisfied with this pump. I hope this helps.. btw, the 4400 psi pump is not the same pump as the 3600 psi pump. They look the same, but the 4400 psi pump is infact stronger...

I love this pump so far, 4200 psi when using my wand, I’m sure it’d do more if I turned it up more, does 3300psi on my 20” 2 nozzle surface cleaner, I have around 12 hours run time on it so far with no issues, very happy with this purchase.Update: still going strong, awesome pump! I’m sure it’s not the same quality as the 800$ Cat pump it replaced but 80 plus hours in it’s still the deal!
