Vacuum Pump Oil

Vacuum pump fluids are engineered to maintain optimum lubrication while achieving the lowest possible vacuum level. LACO’s 20 grade vacuum pump oil is a high quality molecularly distilled hydrocarbon fluid design for use in rotary vane vacuum pumps and high vacuum blowers. Its low volatility and excellent vapor pressure offer extended fluid life, reduced back streaming, and high resistance to corrosive attack. With a low vapor pressure and minimal additives, our oils resist sludge & varnish formation that occurs with lower quality oils. When used in mechanical pumps and diffusion pumps the possibility of cross contamination is eliminated.
