Choosing a beer pump
This was one of the more easy decisions. A pump is a MUST for any 1/2 barrel brewery.
What to look for in a pump;
1 – Rated high temperature >200deg F.
2 – Polysulfone head housing
The March High Temp Brewing Pump
This is pretty much THE homebrewer 1/2 barrel pump. Here is the pump on my current system using 1/1.5 inch sanitary fittings.
You will note that the pump location on the current design is just about even with the bottom left keg. In some instances we have to inject water in to prime the pump. Most of the time it works fine. It’s a tradeoff we made for the current system.
Plumbing the Pump
Ideally, plan your brewery so the pump is several inches BELOW your very bottom keg. This will make for easy priming. I have never ran into a problem where I couldn’t prime.
Other things you will want to do is to install a switch (not on the stand, but away from any water spillage) that the plump plugs into. This is so you can easily turn the pump on and off without needing to unplug it constantly
