BOS specialises in spare parts for Gaulin homogenisers. For the Gaulin 24 – 132T series (55, 90, 132T, 37) we supply everything from plunger packings and valve seats to complete cylinder blocks.
Gaulin machines have a mono-block cylinder: one block that holds the plungers and the pump valves. We supply new blocks, refurbish worn ones in our workshop and stock the plungers, packings, valves and seats that go in them.

Part number search
Type the number from your manual, parts list or the old part. A letter before or after the number may be missing or different: we also show variants, for example with or without J or H.
Not found, or no part number at all? We can reverse-engineer the part from a sample, a drawing or photos with measurements, and make it in our own workshop in Hilversum.
Ask about reverse engineeringSizes are not shown. We confirm the exact version for your machine with the serial number.
No. BOS Homogenisers is independent and not affiliated with SPX FLOW. We supply parts that fit these machines: from stock, made in our own workshop in Hilversum, or reverse-engineered from a sample.
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.
Yes. We ship parts worldwide from Hilversum and work with partners in many countries. On-site service by BOS engineers is offered in the Netherlands; elsewhere our workshop and partners help you.
