Gaulin MC · MC18, MC45, MC15

Cylinder · liquid end
BOS specialises in spare parts for Gaulin homogenisers. Here you find the cylinder parts we supply for the Gaulin MC series (MC18, MC45, MC15, MC7).
The cylinder is where the pressure is made, so it takes the most wear: plunger packings, pump valves and seats are regular maintenance parts. We stock them, make new plungers and blocks, and refurbish worn cylinder blocks.

Send it to us anyway. Old numbers, numbers with a missing or different letter and numbers from other suppliers are often known to us under another code. If a part is not in our file, we can reverse-engineer it.
The part number or a description, your machine type (for example MC45 or Rannie 45.72) and the serial number from the nameplate. A photo of the nameplate and of the part helps.
