Hey Ed,.. No,..I went to air several years ago,..actually I used a roller pump before going to air. I'm asking just starting to use 12V for different applications,.I have simple pump sprayers for small applications and I have the air setup for roofs,..but I needed a mid sized sprayer,..so I put together a 12V cart about a month ago. Just trying to get some info on 12V pumps is all.
As far as the different model "letters',..I bought a 7812-201 SB for my pump. The 5850-201 C is another pump I looked at,..but it would put out to much flow for what I needed. This thread was about the letters and what they mean,..I have another thread addressing the flow and accumulators.
But, I also got confused,..I thought I'd seen a 7812-201 "C",..when in reality,.it must have been a 5850 201 C,..so I was confused,...'cause I don't think there is a 7812-201 c,..Ha,Ha...
