CMP 47, 57, and 67 are high purity paraffinic mineral oils that provides excellent lubrication, low varnish forming tendencies, and superior water separating properties. The three viscosity choices enable the use of these unique fluids in a wide range of vacuum pumps.
CMP 47 is engineered for use in small rotary piston pumps up to 150 cfm but can also be used in large rotary vane pumps that do not require lower vapor pressures.
CMP 57 is engineered for use in rotary piston pumps from 150 cfm to 300 cfm with operating temperatures up to 160 °F.
CMP 67 is engineered for use in rotary piston pumps from 150 cfm to 300 cfm with operating temperatures above 160 °F. and is also an excellent choice for pumps that are older and require a higher viscosity to seal properly due to wear on the internal components.
