Q: I'm replacing a pump with 3200 psi won't I lose some cleaning capability?
by Dan Farrren from New York on April 22, 2015

A: Normally, the 3200 PSI rating is a PSI rating in bypass mode. However, this CAT pump is a true 3000 PSI unit.

In order to make sure it is compatible with you machine you need to be sure of a few things.
1. Engine shaft diameter size
2. What is the HP or CC of your motor
3. The number of bolt holes your pump has
4. Whether your pump is horizontally or vertically mounted
After knowing those things we can better assist you in which replacement pump is right for you.

Q: Will this pump fit my power washer I have a DeWalt with a Model #3DNX27GSI Triplex pump? And if not which one will?
thank you

by Ron Mardirosian from California on November 06, 2014

A: Which Honda engine do you have on your DeWalt? The model number will begin with GX,GC,GCV, and followed by 3 numbers. Get back to me with this information so I can confirm compatibility with that engine.

Best Pump Ever!
I never write reviews but this pump deserves it. I'm a tomato grower from Mexico. I tried many pressure washers (from Karcher to NorthStar) and they always fail really fast (3 months at best). I have been cleaning around 400 boxes a day since 2 years ago and has never failed!

2 hour a day for 2 years = around 1200 hours working with no problem on a Honda 5.5hp engine. Oil changes every now and then but not calendarized.

Now I'm here writing this review because I know it has to fail... more

Thank you for posting your review- they really do help folks trying to choose a replacement pump. CAT makes a terrific product and they are rebuildable, letting you make the most of your investment.

Ask Mike- He's Clueless
Mike told me that my new cat pump would fit my 3100 Simson pressure washer after exchanging emails about the moving handle might be in the way he insured me that it would fit. Then I purchased the pump and as I suspected the pump wouldn't go on past the handle so I cut the handle no big deal I'll weld an extension pieces on.

Now I have room to slide the pump on when I slid the pump on only to find out the shaft on my Honda 190 motor was 1/4" to long now I have to cut the shaft.

I'm sorry you had problems fitting up your pump- there isn't a big cross-reference that lists all pumps and all the pressure washers they fit; it would be a lot better if there were.

That's why every pump page says "See the Owner's Manual (under the Specs tab) for dimensions" so you can match your particular setup against the pump specs.

If you had called me when you realized it wouldn't fit, I would have authorized the return without the restock fee since it was my error. Since you've modified the pump I'm sorry, but we can't take it back. I'm glad you were able to make it work.

We've checked back through all of the email sent to '' and I'm sorry- there wasn't anything from the email address on your file, which is why you didn't hear back from us. There is a team of folks that take care of pressure washer customers, and we log every email, review and phone call.

We appreciate your business, and apologize for any inconvenience.

Great Replacement Pump
I have a John Deere 3000psi with Honda engine. The pump lasted 4 years without issue but then it stopped. The CAT pump arrived and I bolted it on and wow! Getting 3200 psi at 75% adjustment.

Used to power wash a brick and vinyl 4000 sq foot house with liquid chlorine. The house looks brand new.

If you ran the chlorine through the pump, I'm sorry to say that voids the Factory Warranty. Chlorine is a very harsh chemical and will eat through the seals in no time.

Please make sure that you flushed the pump thoroughly with fresh water to get the chlorine out, and you may also want to run a Pump Saver product (any brand is fine) through to re-lubricate the seals.

Fortunately you can also buy a rebuild kit through CAT Pumps if the seals wear out prematurely.
