The famous March brewing pump is now available with a stainless head. Having sold pumps for all grain brewing for 20 years, MoreBeer! can recommend this pump as having the longest lasting motor. This is the exact same pump as the famous 815pl (our H315HF) but with stainless head.

Because the pump is magnetic, where the magnet spins on the other side of a sealed wall, it is seal-less and easy to sanitzie. All the parts that come in contact with liquid are made of Stainless Steel, Teflon, Silicone or Ryton/Teflon/Glass. The standard motor can be run on either 50 or 60 hertz (there are performance differences between the hertz options). The 815-SS Beer Pump motor has a six foot cord, a plug, and a base.
