How similar are all the different boom pumps that are made in Korea? KCP, DY, Jun/Jin etc. We run 3 Jun/Jin(alliance) and couldnt be happier. They all seem very similiar. Just wondering if somone could rank them...

The rankings need to consider product support, availbility of parts and when you see a rep from the company if you have a problem. I wont rank anyone, but Alliance does an excellent job with customer serivce and support from my experience.

I have owned Junjin ans KCP pumps, in my fleet the KCP pumps have less issues. The pumping system is an open system and the electrical system is simple.
