Northern Brewer Anti-Gravity Transfer Pump

Some homebrew gear has a wide range of use, and some fills a very specific purpose. Those that fill a specific purpose typically become a critical piece in your process that you wonder how you managed before you had it. For me, that was the Anti-Gravity Transfer Pump from Northern Brewer. This pump is specifically intended for use in transferring beer or wort from vessel to vessel during your fermentation and/or kegging processes.

Closeup of Pump Head

The Anti-Gravity pump is a diaphragm pump, which is different than your typical wort pump. Wort pumps are usually an impeller design with a pump head inside with rotating blades that push little bits of fluid along from the inlet to the outlet as they spin. A diaphragm pump has a flexible membrane inside that oscillates back and forth like a trampoline. When the membrane is pushed in one direction, it compresses the fluid and forces it to the outlet. And when the membrane is pulled in the opposite direction, it creates a vacuum in the pump chamber which draws fluid in. A set of check balls ensures flow only goes in one direction.
