Mutigrade Hydraulic Oil


Product Description

STARTEC HESSINOTE HVI series are premium quality anti-wear hydraulic oils specially developed for applicationssubjected to wide range of temperature or where small viscosity change with fluctuating temperature isrequired. They are formulated with high quality paraffinic base oils, a highly shear stable polymer and anadvanced additive system to meet the stringent requirements of modern hydraulic systems using highpressure high output pumps and critical requirement of other hydraulic system components such as highaccuracy numerically controlled machine tools and those employing close clearance servo valves. Theseoils provide excellent protection against oxidation degradation, rust & corrosion and wear. They alsopossess superior foam control, water separation and rapid air release properties.

They are available in ISO viscosity grades 46, 68 & 100 and exceed the performance requirements of globalindustry standards viz. DIN 51524 Part 3 HVLP, AFNOR NFE 48-603 (HV) & ISO 11158 HV and majority ofthe international OEMs viz. Poclain, Hitachi, Cincinnati Lamb, Eaton (Vickers) and Denison.

Features & Benefits

  • Exceptional anti-wear property results in longer pump and component life and reduces costs
  • Extremely high viscosity index assures equipment protection at cold start-up temperatures andprotects system components at high operating temperatures
  • Excellent shear stability minimises viscosity loss over time and exhibits “stay-in-grade” performanceunder high shear conditions
  • Excellent thermo-oxidative stability controls the formation of sludge & varnish and improves oil life
  • Superior demulsibility helps in faster separation of water from oil and resists formation of emulsions
  • Special rust & corrosion inhibitors protect multi-metallurgy components even in presence of moisture
  • Rapid air release property minimises chances of pump cavitation leading to trouble free operations
  • Compatible with multi-metals and sealing materials commonly used in hydraulic systems


  • Hydraulic and power transmission systems subjected to a wide range of ambient & operatingtemperatures
  • Critical hydraulic systems such as high accuracy numerically controlled machine tools and thoseemploying close clearance servo valves
  • Hydraulic systems of excavators, cranes and hydrostatic drives subjected to most severe outdooroperating conditions
  • Hydraulic systems operating under high pressures and requiring high degree of load carryingcapability and anti-wear protection
