E2M8 Coupling Source

Anyone have a line on the “fan coupling assembly” for an E2M8 that doesn’t cost $500? We just got two in house and they both have broken couplings which apparently cost almost as much as a refurb pump.

I imagine there has to be an aftermarket manufacturer given how ubiquitous these pumps are and how rotarty vane pumps are notorious for stripping couplings if they get too much liquid in them but for the life of me I can’t find it.

I might have one out back in my graveyard.


That would be Fan.Tastic. Let me know if you can scare one up!


There’s two versions. Uk and USA version. Measure shaft size.

Sorry for the delay, didn’t have a chance to pull the motor back off the one pump today and the other got brought to the toolroom. I’ll get you tomorrow. I appreciate the help!
