high proof High proof pump needed any suggestions?

[Claire11]

My high proof pump stopped working out of nowhere. It’s a McFinn technologies. Trouble shot over the phone but still not working. Changed all O-rings even though they looked fine. No suction of liquid. Any suggestions? Anyone have one for sale in NY State? Thanks.

McFinn makes a few models of pump. Is it a US-FIP? No suction of liquid could indicate an air leak somewhere, which would typically be fixed by changing o-rings & seals until the culprit is found. If it is a flexible impeller pump I would try introducing some head pressure by partially closing a valve somewhere downstream. Try this in both directions if possible. This assumes you can get liquid to the pump inlet somehow. If it can pump at all and you introduce pressure downstream, any leaks may become visible.

If possible, use different hoses, gaskets, valves, etc. so that the source of the issue can be narrowed down to just the pump head.

We're not in NY, but let me know if we can help getting you a new pump. We sell a lot of pumps to distilleries. Good luck.

If you need a new high proof pump we have them starting at around $400.00  paul@distillery-equipment.com

If it is a high proof pump, one would assume you're using a double diaphragm air driven one.  What is the application?  Filtering?  What's the volume?  These are cheap and easy set ups if so.
