I recently purchased a 12JC Berkeley pump, stamped on the ID plate 12JCA-H.
I think the A stands for the impeller "A" that was factory fitted, but the "H" I don't know.
It is extremely rare to find Berkeley pumps for sale in South Africa, this one even has a Jet-O-Vator fitted, which makes it even more of a good find for me.
I will be using this pump as a back up or if I find a nice hull......
Does the "H" stand for something specific?
