Rozep AW Hydraulic Oil

Product Description:


Texas Oil Rozep AW Hydraulic Oils are superior quality anti-wear hydraulic oils formulated from the finest high quality base stocks and are further fortified with high performance additives to enhance their capability. Engineered with a superior additive package, they are designed for superior performance in reciprocating compressors subjected to sour, wet, and high-pressure gasses. They are recommended for use in high pressure hydraulic systems which utilize vane, piston or gear pumps in addition are rust and oxidation (R&O) inhibited oils providing excellent performance in hydraulic systems, compressors applications where long lubricant service life is required and other applications where a high quality anti-wear type oil is required. Their superior oxidation resistance enables extended oil drain intervals, with significantly reduced sludge, varnish and carbon deposits on internal parts, pumps, and other internal components.

Texas Oil Rozep AW Hydraulic Oils considerably reduce the necessity of cleaning and other maintenance, provide excellent protection against wear, as well as increase productivity and provide excellent filtration characteristics. They have excellent demulsification ability to prevent water from deteriorating internal components.

Texas Oil Rozep AW Hydraulic Oils meet the performance requirements of Hagglunds- Denison,Trinova Vickers, Cincinnati Milacron, Lee Norse, Jeffery and others.

Key Features :

  • Superior additive package with excellent anti-wear protection.
  • High performance additive system with anti- oxidant, anti-foam agents, rust and corrosion inhibitors.
  • Excellent protection against fluid deterioration with high base oil and additive performance.
  • High resistance to foaming and excellent air release.
  • Protects metal surfaces from the damaging effects of entrained water.
  • Protects against the corrosive effects of hydrogen- sulfide and other sour gas components.
  • Allows quick release of entrained gasses.

Customer Benefits:

  • Exceeds performance requirements for manufacturers’ pump specifications, provides longer life and performance.
