Gaulin Spare Parts

Gaulin Homogenisers: Over 125 Years of Pioneering Technology

Auguste Gaulin patented the first homogenizer in 1899 in Paris, France — a breakthrough that transformed the dairy industry and laid the foundation for modern high-pressure homogenization. Today, Gaulin homogenizers remain among the most widely installed machines in dairy plants, food processing facilities, and pharmaceutical operations worldwide.

Following a series of acquisitions — from Manton-Gaulin to APV, then SPX FLOW, and most recently JBT Corporation — the Gaulin brand continues under the SPX FLOW / JBT umbrella. However, many operators find that sourcing genuine Gaulin spare parts through the OEM channel has become increasingly expensive and slow. That is where BOS Homogenisers steps in.
