recommends the highest grade and quality of oils and
greases for maintaining high performance of the
products we sell. Our fluids and sealants include
mineral-based, silicone-based, synthetic-organic
compounds and fluorinated materials (PFPE).
strongly advise using only the recommended grades and
quantities of fluids and sealants to maintain the high
performance of our products. The use of inferior
materials can lead to a reduction in pumping system
efficiency and performance, ultimately leading to the
potential failure of equipment.

Our Ultra-grade oil for rotary vane pumps is produced
using a two stage hydro-treatment process. This
process delivers very pure oil with exceptional
These materials are used for Diffstak and diffusion
pump fluids and greases. They comprise either di-methyl
siloxanes or phenyl methyl siloxanes.
These include various hindered esters, phenyl ethers
and naphthalene-based compounds. They are offered for
use in Diffstak and diffusion pumps, but they can also
be used as rotary pump oils in certain unique
Fluorinated materials (PFPE) - particularly for
These are perfluoropolyethers. Perfluoropolyether is a
fully fluorinated material free from other halogens
and from hydrocarbons, and so is of particular value
where freedom from hydrocarbons is important.
Perfluoropolyether fluid is available in grades
suitable for use in rotary pumps. A low-vapor fomblin
grease (AR555) is available which combines good
lubrication properties with superior vacuum
