Mobil Pegasus SCF Extra

Mobil industrial , Canada

PREMIUM QUALITY PART SYNTHETIC GAS COMPRESSOR LUBRICANT

Product Description

Mobil Pegasus SCF Extra is a custom-blended hydro treated mineral oil / polyalphaolefin (PAO) synthetic hydrocarbon oil. The proprietary multi-function silicone additive provides enhancement as a lubricity improver, an anti-foamant to minimize foaming, and a pour point depressant to provide lower temperature operation capability.

Mobil Pegasus SCF Extra uses a proprietary corrosion inhibitor additive system to reduce the effects of the corrosive materials present in the compressor streams and operating environment where the lubricant is subjected to harsh chemical environments including the presence of (H2S).

Mobil Pegasus SCF Extra thermal and oxidation stability can help to provide longer life and better control of deposits, sludge and varnish.

 

Features and Benefits

Mobil Pegasus SCF Extra is a custom-blended hydrotreated mineral oil and polyalphaolefin (PAO) synthetic lubricant specially formulated to offer excellent performance in demanding gas compressor applications.

Mobil Pegasus SCF Extra lubricants offer the following potential features and benefits:

  • Part Synthetic blend is more cost effective than full synthetic (PAO)
  • Good Demulsibility
  • Good Thermal Stability to control deposit formation
  • Very low vapour pressure
  • Soluble with Hydrocarbons
  • Exceptional control of sludge, varnish, or lacquer formation
  • Very Good lubricity
  • Good Water resistance

 

Applications

Mobil Pegasus SCF Extra is a premium lubricant/coolant designed for process and gas rotary screw compressors and is well suited for low specific gravity gas compression in low ambient temperature conditions. Mobil Pegasus SCF Extra is also recommended for use in rotary screw, vane and reciprocating compressors in industrial applications requiring a high viscosity fluid.

Mobil Pegasus SCF Extra is especially effective in combating corrosion and promoting long life in sour hydrocarbon gas compressors. Mobil Pegasus SCF Extra lubricants are compatible with the same system elastomers and seals as used with petroleum based products.
