Hey all, question for you.
We have a Chinese sourced pump that circulates the glycol from the glycol reservoir to the chiller. The seal failed on it a few months ago and we had it replaced. It ran for almost four years without an issue. Now since the seal has been replaced, it failed in three months and dumped a bunch of glycol.
This is a water cooled pump that we have never had water on due to the fact that it is already cold from the glycol. The pump repair man now wants to circulate glycol in a loop through the pump cooling chamber. He wants me to create a loop where the pump water chamber is filled with glycol but tapping into the face (in) of the pump, and tapping into the out of the pump.
I have some concerns with that.
1)Can that chamber handle the pressure that the pump generates? My question there lies in the fact that when we run water through it, there is little to no pressure on that chamber.
2) will I be introducing particulate from the pump loop into the glycol system as a whole, especially as that seal wears?
3) The logistics of tapping into that pump face is daunting as we do not have any additional space to extend the pump connections to the rest of the system.
Let me know your thoughts.
Thanks: Mills
