Description

TMC 19 mechanical pump fluid is high-grade oil, molecularly distilled hydrotreated paraffinic oil for use in mechanical vacuum pumps. Good vapor pressure and low backstreaming make this a good choice for non-corrosive vacuum applications. This product will support vapor pressures down to 1x10-5 Torr.  If a deeper vacuum is desired, TMC 20 would be a better choice. 


TMC 19 is used in Leybold, Edwards, Welch, Agilent, Alcatel, and Varien pumps.


Independent Lab Study TMC 19 vs Inland 19

An independent testing laboratory performed a modified RBOT D-2272 test to determine the oxidative stability of TMC 19 compared to Inland 19.  This test employs a method to achieve rapid oxidation of the lubricant tested and then measure the degradation characteristics of the oil.  

In the test results below you will see that even though the TMC 19 lasted longer than Inland 19 it also exhibited less viscosity change and less sediment weight at the conclusion of the test.

Through molecular distillation, light end fractions are removed, resulting in lower vapor pressures and reduced backstreaming compared to undistilled refinery products. These properties allow TMC 19 to be used with the more expensive diffusion pump fluids that can otherwise be contaminated by a lesser fluid. Compared to refinery fluids, TMC 19 offers reduced maintenance costs, better pumping cycles, longer fluid life, and a cooler running pump.  TMC 19 is a high-quality oil that will make your pumps last.

The price and quality make this the perfect choice for many applications, even where lower-cost oils are used. Not recommended for oxygen and highly reactive gas loads.
