CMP 20 Ultra HT
Semi-Synthetic Vacuum Pump Fluid
Specifications:
Vapor Pressure @ 25° C 1X10-7 Torr Viscosity @ 40° C. 103 cst. Pour Point -12 °C. Specific Gravity @ 22° C .86 g/ml Flash Point - C.O.C. 268°C. 515°F Fire Point - C.O.C. 304°C. 579°F
CMP 20 ULTRA HT is manufactured from the same technical white oil base stock as the EDWARDS ULTRA GRADE 20.
The difference is that we blend in a state of the art anti-oxidant package under high vacuum molecular distillation that gives our product superior oxidative stability.
CMP 20 ULTRA HT is engineered for use in any medium to large rotary vane pumps and exhibits properties normally only found in full synthetic hydrocarbon vacuum pump fluids at a much lower cost.
INDEPENDENT LABORATORY TESTS PROVE IT !
Modified RBOT D-2272 tests performed at an independent testing lab comparing the CMP 20 ULTRA HT to the INLAND 20 ULTRA and the EDWARDS ULTRAGRADE 20 showed these results.
