Hi Bill, Can another brand name pump like General or AR or Cat pump replace the Karcher 4000 axial cam pump? If yes, is it just to take out and change or do you have to modify? Thanks in Advance, Melvin.

Answer
Unfortunately you could not purchase this machine with another brand of pump, meaning the machine could not be customized from the factory. However, you could definitely purchase a General Pump, CAT PUMP, or AR brand pump and install it on this machine with no modifications needed. You would just have to make sure that the replacement pump you purchased accepted a 1" diameter shaft and was designed for a horizontal installation.

How does the Karcher compare to something with a general or cat pump? what's the difference between a axial & triplex pump? How much does a new pump for it cost? or to rebuild the one thats on it?

Answer
When it comes to a unit with a General or Cat pump, the difference in quality is going to be much different. It really comes down to the type of pump. The General and Cat pumps are going to be a tri-plex plunger pump made of ceramic. Going to be much more durable as well as a better quality. Axial Cam pumps are made from aluminum and not going to give you the durability you are looking for the long term.

Replacement pumps are typically going to be anywhere from $250-$500. The plus side to a tri-plex pump, you can actually rebuild these, where an axial cam cannot be rebuilt.

Thanks,

Bill I am going to buy a pressure washer, and the Karcher( 4000) I was told was the best from some friends. I went to a couple of shops and the owners didn't recomend buying the Karcher. What do you think, I just don't want to buy something that won't last.

Answer
Karcher actually makes really good quality pressure washers, especially their gas models. Karcher uses their own branded German engineered pumps on all of their gas pressure washers. With this model having a Honda GX engine on it, you are absolutely getting a quality pressure washer. You might have heard some negative comments on Karcher products due to an issue Karcher was having a couple years ago with their after sales support. Since then, Karcher has drastically improved their warranty procedures.

I would have no problem at all recommending Karcher's gas models or their higher end electric models. We have had good luck with selling their products.
