The CHUGGER PUMP® is used for Homebrewing. It is typically used to transfer both hot and cold liquid between brewing vessels. It is important to note that a CHUGGER PUMP® is not a self-priming pump so DO NOT RUN DRY! The pump head must be flooded with liquid prior to turning on the pump. The CHUGGER PUMP® is also magnetically driven which helps you control the flow rate by adding a ball valve on the discharge side of the pump.
