BOS specialises in spare parts for Rannie homogenisers. For the Rannie Blue Top series (12.50, 45.72, BT 45.72, BT 36.72) we supply everything from plunger packings and valve seats to complete cylinder blocks.
Rannie machines have a three-piece valve housing: suction, discharge and plunger blocks bolted together. We supply the blocks and every wearing part in them: plungers, packings, guide and nut rings, pump valves and seats.

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.
