Pumps are used throughout the brewery, including in our whirlpool.

On the blog, we’ve been slowly taking you behind the scenes at Prost Brewing to explain all the technical elements that go into making excellent German-style bier. We recently discussed pipes and valves in the brewery, and today we’re taking a look at the pumps that move fluids through the pipes or into vessels.

We use different types of pumps in many capacities at Prost Brewing, including sanitary and non-sanitary uses. Some examples are moving wort between our copper kettles, pumping wort into the whirlpool, dosing yeast into our fermenters, pumping water into our kettles for cleaning, and so much more. There are two main types of pumps used in breweries: centrifugal and positive displacement pumps.

The centrifugal pump is the most common liquid transfer pump in the brewery. It consists of a motor-driven spinning rotor or vane. The spinning vane’s action creates a suction that forces liquid out at a discharge port. Beer and cleaning solutions are commonly transferred using these types of pumps.

The positive displacement pump is the other kind of pump, and features a robust design that creates an area where fluid is trapped and moved forward via the action of the pump. It’s meant to move fluids in a controlled and staggered manner. Common uses are yeast dosing and filter media injection.

With all this talk of moving fluids around, including bier, are you getting thirsty yet? Stop in soon and enjoy the fruits of our labor. Prost!
