A superior general purpose high viscosity hydrocarbon fluid designed for use in piston, rotary lobe and large rotary vane vacuum pumps. Its high viscosity index provides the lubrication and sealing properties; its low vapor pressure provides the ultimate pressure needed for proper pump operation. This fluid also offers excellent resistance to water emulsification and oxidation in non-corrosive applications.
A molecularly distilled hydrocarbon mechanical pump fluid designed for use in direct drive rotary vane pumps. Its low vapor pressure reduces system back streaming and its thermal stability provides resistance to oxidation and sludge formation. Use of this fluid offers longer fluid life, improved pumping cycles, lower maintenance costs and cooler running pumps.
Flushing fluid has been specifically formulated to assist in the internal cleaning of particulate and sludge build-up due to process contamination in mechanical vacuum pumps. The addition of a low vapor pressure solvent actually dissolves sludge and varnish build-ups without damaging seals, gaskets or O-rings. Most flushing fluids are low end hydrocarbon oils that have very little sludge cutting ability.
Very durable and possess characteristics that produce more efficient operation with less maintenance. Their excellent chemical and thermal stability make them highly resistant to oxidation at operating temperatures. This allows longer service runs without deterioration even under adverse pumping condition. Their very low vapor pressure produces better vacuum levels with low back-streaming rates for faster cycling and cleaner systems.
Univac 220, Univac 300, and Univac 550 are phosphate fluids for mechanical pumps which are clear and amber in appearance. These fluids are an excellent substitute for hydrocarbons fluids in vacuum systems pumping oxygen at a greater concentration than atmospheric. Phosphate fluids exhibit good oxidative resistance and thermal stability and are considered an inexpensive alternative to inert fluids.
