Mechanical Pump Oils

Mechanical pump oils Edwards supplies the widest range of oils of different viscosities and specifications to enable customers to obtain the best performance from mechanical pumps under different application conditions

Mineral oils are manufactured by a hydro treatment process to reduce carcinogenic risk. All are specially prepared for high vacuum use, having low vapour pressures even at high temperatures. The particular mechanical pump specification should be consulted to find which oil to use.
