LUBRIPLATE VACUUM PUMP OILS are high performance, non-detergent mineral oils. They possess exceptional flash and fire points, as well as high V.I.s (Viscosity Index). LUBRIPLATE VACUUM PUMP OIL is recommended for most rotary vane and rotary lobe vacuum pumps. It is designed to alleviate the sludge, carbon deposit and contamination problems commonly found in industrial vacuum pumps. LUBRIPLATE VACUUM PUMP OIL LIGHT is recommended for rotary vane vacuum pumps typically associated with delicate instrumentation. These vacuum pumps generally have a drip oiler involved. The use of this oil will provide for optimum lubrication without the formation of carbon deposits.
