AP303 - Turbo Pump Oil

Brand: Apiezon

Product Code: AP303

Availability: On Request

Manufactured from high quality polyol ester base stock 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.

Temperature Range

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

 

Easily Removed

When servicing of pump bearings is carried out, Apiezon AP303 is easily removed by washing away with warm soapy water or by using any aromatic hydrocarbon solvent (toluene, xylene). For a more environmentally friendly solvent, we recommend Limonene.

AP303 is not soluble in alcohols (ethanol, IPA) or ketones (acetone, MEK) so these are not effective for cleaning

 

AP303 Lubrication Oil and Turbo Pumps

AP303 Turbo Pump oil is used in turbo molecular pumps with conventional bearings which require a high grade lubricant with low vapour pressure. High-speed bearings such as these, with a low bearing load, require oil with a low viscosity. AP303’s polyol ester formulation provides excellent lubricity along with good resistance to ageing, which provides a long service life. It is advised to degass the turbo oil before use to shorten pumping time and prevent foaming
