SV-SIGMA™ is an alternative to which commonly used oils ?

SV-SIGMA™ is used as an alternative to now discontinued DC-704. This is also an alternative of CVC-4. In fact volume of sale of SV-SIGMA™ diffusion pump oil is much larger than that of CVC-4.

What is the normal working life of SV-SIGMA™ diffusion pump oil ?

Working life of the oil depends on a number of parameters like the application where it is used, condition and maintenance of plant etc. But normally customers get a life of 1.5 – 2 years.
