Hey All,
We have a Thomsen centrifugal pump that we use for hot a cold side. After boil, we'll hook our pump to the kettle, then to the heat ex. After knock out, if we shut the pump off, it will seize up, requiring it to be broken down to clean out and cool off. Our particular model did have a recall for the seal, but the replacement hasn't seemed to work in this situation. There is no visible damage to the plate or o-ring, and it never has trouble cold side.
Just wondering is anyone has dealt with this issue, it's never been a problem for me in other breweries. The pump head is held on by a clamp instead of bolts, is this a pressure issue?
