The Brewing Company in Pennsylvania has brought in Netzsch Nemo progressing cavity pumps for the removal of spent grain.

“After all of the extract has been taken out for brewing beer, the remaining material – the spent grain, including spent hops – is a very high-moisture product,” a brewery spokesman said. “We used this type of Netzsch pump for the same application in our Downingtown facility. We have experience with these pumps – they just run – so it made sense to install the same pump technology in our new Parkesburg brewhouse.

“To this point, we have done no maintenance on the Netzsch pump at Parkesburg. We just let it run. The same Netzsch pump that conveys spent grain in our Downingtown facility ran for five years before the stator needed replacing.”

The 19,700 square meter Parkesburg facility features a German-built brewhouse with a production of about 10 brews a day for an annual output of approximately 225,000 barrels.
