pump leak mystery - looking for help
(OP)
Hey guys,
We have a thermal fluid pump at our plant that is leaking from the shaft seal. We have tried 2 different brand pumps now with the same result. It is a slow leak from the shaft seal. Both pump manufacturers have tried looking at the information for the system with no ideas. When disassembled - the seals look brand new. We would like to hire a 3rd party to help us with the issue. Can someone suggest an entity that has experience that might be able to assist? Google did not help us with finding someone so far. If this constitutes as "recruiting" - apologies. I am only hoping to get a couple good suggestions for company names

Have you tried your seal vendor direct?
What did you search on?
USA or somewhere else?
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Contact the designer and builder of the system.

Otherwise, you probably need a different pump design, like sealess, or one where the seal is far from the hot parts.

If the (a) expansion drum is not inert gas blanketed, or (b) if the HTF fired heater is not designed to keep max tubeskin temp at less than max recommended tubeskin temp at max firing rate, then you may have thermal decomposition/ cracking of this HTF (or oxidation products) and this flashpoint value of 410degF may not be applicable. It is often next to impossible to confirm that (b) is actually seen in practice.
