I clean and check my raw water pump but I saw something strange. When I turn the shaft only snap ring turn with and in fact the upper ceramic disc is suppose to turn the other disc to form a good seal against the water. When I check I don't see nothing for blocking the disc with the shaft. The snap ring turn on the flat copper washer and there is friction. Is it normal. I am not able to post the little video. why. Thank you
andre : In a Mainsheet Tech note article on the Sherwood pump - I mentioned that that copper/bronze "snap ring" should be replaced with a stainless one. That way the stainless won't corrode leaving the one ceramic surface loose against the other ceramic surface.

Ok but why when I turn the shaft the first ceramic disc don't turn . My snap ring is new. There is nothing for blocking the disc on the shaft. The first disc is supposed to turn on the other to form a seal.
Andre : All I can say is to take the pump off and disassemble it - and then reassemble.

Ok thank probably if I can't find the problem I will change for an oberdorfer model
Andre : You can do that to or send you pump to DEPCO and have them fix it.
