Product Description

HI-PUMP is supreme performance anti-wear hydraulic fluid formulated from S-Oil's ULTRA-S* base stocks and advanced additive system designed for wide temperature range applications and a wide range of heavy-duty equipment requirements. HI-PUMP also provides effective low and high ambient temperature performance due to high viscosity index. It's excellent thermal and oxidation resistance delivers good performance and extended operating intervals. * The trade-mark of S-OIL's Group-Ⅲ base oils.

 

Applications

• ​Hydraulic systems operating under high pressure and/or temperature (earthmoving, excavator, loader, etc)
  
• High-pressure vane, piston or gear pumps
  
• Sensitive hydraulic circuits requiring absolute filterability of the fluid (very fine servo valve play)

     : plastic moulding machine  

• Any hydraulic systems where the risk of contamination of the environment and waters exist
  
• Any application where an anti-wear, high-performance oil is necessary​

 

Features

• ​Excellent anti-wear properties ensuring protection of machine parts.
  
• Exceptional oxidation and aging stability : greater service oil life and lengthening of oil change intervals
  
• Environmentally friendly formulation
  
• Prevents formation of deposits in the circuit thanks to remarkable thermal stability : cleaner circuits, less clogging of the filters
  
• Reduced maintenance costs ​
