Hey Guys, Long time reader, first time poster so here's my introduction if anyone cares. Names Danny and I'm an Industrial Mechanic at the Saint Louis Brewery (Schlafly brand beers) in St. Louis Missouri.
So, now that that's out of the way, I have some questions about the progressive cavity pumps that you're using to move spent grain.
We are having to replace our stator about every three months which adds up pretty quickly(around $1300 each go around) Our pump supplier seems to think that this is very unusual to have to replace the stator this often, but hasn't been very helpful about finding a solution. I think they like that 1300 dollar sale every three months.
We're using a Netzsch NEMO pump that discharges into about a 100 foot run of a 6" stainless pipe. There is around 40 foot of discharge head, and pumping around 100psi at the outlet of the pump. According to the pump curves I've seen, everything says that our pump is sized correctly.
Currently We're churning out around 60,000 bbls a year which can give you an idea of how much this pump is used, I can also get stator run time when I'm back at the Brewery (it resets every time we change a stator)
Does anyone out there have a similar setup as us Or have any suggestions?
What brand pumps are you using and what kind of life are you seeing out of your stator?
Thanks Guys, any help is much appreciated!
