CMP 51 is a severely hydro-treated paraffinic oil put through a molecular distillation process to remove light end fractions and contain a complex additive package that aids in gas ballasting off water vapor and prevents the accumulation of varnish, particulate and sludge on the internal components of the vacuum pump. The use of CMP 51 fluid in high particulate or water vapor applications will increase the service life of your pump and allow for less extensive and lower cost repairs.
