That’s why when it came to choosing a bearing for a newly designed side-entry tank mixer, a major manufacturer decided to put GRAPHALLOY bushings to the test. Since this mixer was for a brewery application (part of the beer making process), the bushings needed to be oil-free, capable of being submerged and FDA acceptable.
Side-entering mixers work efficiently when a tank is too large for convenient installation of a top-entering mixer or when headroom is severely limited.
The company had been using GRAPHALLOY bushings in their various industrial mixers for many years and were pleased with the long life and low maintenance. Prior to using GRAPHALLOY, they had used a glass-filled Teflon material but their customers complained about the short life of these bushings.
Their new mixer is a high-efficiency, robust side-entry mixer designed for applications from 10,000 to 1,000,000 gallons, speed is 154 RPM, and temperature is 200°F.
Working with Graphite Metallizing engineers, they purchased thirteen pieces of GRAPHALLOY FDA acceptable bushings and installed them in the mixers in their brewery customer’s tanks.
