Vacuum & Booster Pump Oils

Apiezon oils and fluids for vapour booster and turbo pumps are respected around the globe for their superior quality and stability.

M&I Materials Limited manufacture the range of Apiezon oils and fluids in our purpose built factory in the UK, with Apiezon AP201 as the flagship vapour booster pump fluid with an exceptionally high degree of oxidation resistance.

Widely regarded as being far superior to other low quality imitation vapour booster fluids, AP201 is even specified by some pump manufacturers and even warn that using other fluids can actually invalidate their own warranties.

Apiezon AP303 is a robust and proven lubricating oil for use in turbo molecular pump bearings. It offers a range of benefits, including excellent lubricity and long service life.

It also has a wide operating temperature range which makes it suitable for continuous use at typical turbo pump operating temperatures. Apiezon AP303 also has low vapour pressure, meaning that it will not readily evaporate in operation.

Finally, Apiezon J and Apiezon K oils are sealing oils which can be used in a variety of applications. With very high viscosities, these oils are well suited for rotary glands in particular – a type of seal where the turning shaft protrudes through the inner diameter of the O-ring.
