I have two march pumps I use in a HERMS system and one was always a bit noisier than the other. This morning as I started up my system for an AG the pump was extra noisy then it starting squealing and screeching and I knew I was F'd. I pulled the pump housing apart and didn't notice any damage to the impeller but I think there might have been a gasket or something where the impeller shaft sits in the top of the polysulphone head. I put it back together and could not get the pump to prime and then the screeching noise came back.
Has anyone had this problem before? Has anyone pulled the head apart before. Are there other parts that are missing? I bought this from Northern Brewer so hopefully I can get it exchanged.
