Been running my 10-14 for the past 20 years. Second pump, third gun. Looking into a like and kind replacement to shoot "Cat's" and maybe WB. Yes I know this is like asking your preference between a blond or a brunette. We are a heavy use in shop and in field. I have had good luck with CA Tech equipment over the years. For a second unit, I also like the cost factor of a non-kremlin?

You say you are heavy use, so that tells me you are going to use the equipment all the time. If it was me and I was using it all the time I would want something top of the line.

If you are getting into some water base coatings that are thicker a 14:1 pump is not sufficient, if you talk to the experts the pump creates a shear effect on the fluid. Don’t get me wrong , people are still using these pumps. The shear effect changes the viscosity of the fluid. There are some good articles that explain this on the internet, check out the American coatings association, they have some good information.

Anyways back to the pump, I would recommend spending a little more and get the Kremlin 30:1 pump, the pump is simply amazing. I have 3 CAT 14:1 pumps and the Kremlin pump, I like it so much that I am in the process of trying to sell 2 of the CAT pumps. Don’t get me wrong, the CAT pumps are also great pumps, they have given me no problems, they are just a little weak for the heavier material.

At the end of the day I think all the companies that make these products have great equipment, so getting something that you have good service close by is also important.

Thank you Scott. Fully understand the shear issue with WB. I also hate the WB finishes, but still are forced to use them at times. Will check into the heavier pump.

Scott where are you located? I am intrested in your pumps.

Thanks jim

Yes Scott!
Where are you?

Dumb question Scott. How does the 30-1 spray Post Cats and C.V.'s?

the ratio is not creating the shear. the shear is created by the very small passages in the cat pump small fluid passages as would any pump made by graco, binks, etc. specifically the upper ball check area first then the lower ball check area. if you go to a higher flow rate pump say upwards of .8 to 1 gpm typically a 14-1 will handle most wb as most of the ones that i spray will atomize at approx 1000-1200 psi while it is certainly at the higher end of my pumps pressure rated it certainly is not anywhere near its flow capacity or max strokes per minute which is really what wears a pump out, which is strokes per minutes or the number of strokes the piston rubs against the upper fixed packing of the pump and cup packing on the piston rod. hope this gives a better explanation of wb shear to everyone related to pump shear for waterborne coatings

goodluck

I am located in the great white north, in Western Canada.
I think the Kremlin pumps are the best AAA pumps available as far as transfer rate. I also have fantastic service available for them.
I will also admit that they are expensive , I didn’t realize they had gone up as much as they have, so that could be a definite disadvantage for some. Having said that, I am not sure what the other manufacturers are as far as price point, maybe they have gone up as well and I am out of touch..

Equipment is all based on the opinion of the finisher, just like your favourite truck is a GMC and mine is a Ford, or vice versa. Like I mentioned earlier, I think all the pumps are good these days, that is the only way a company can stay in business.
