GEARLED ZP Series
 

Description

PSO Gearled ZP oils are the range of mild EP additized products incorporating anti-wear properties. They are inhibited against oxidation, corrosion and foaming. PSO Gearled ZP oils are available in six viscosity grades to meet the specific application requirement.
 

Applications

  • PSO Gearled ZP is suitable for mild EP application requirement and especially blended to cater the lubrication requirement of industrial gearboxes, where extreme pressure additized lubricants are not recommended.
     

Benefits

  • Good oxidation resistance and thermal stability.
  • Good anti-wear performance, reduced component wear.
  • Available in six viscosity versions for specific application.

GEARLED EP Series
 

Description

PSO Gearled EP gear oils are available in seven-viscosity range (VG 68 - VG 680). These are lead free extreme pressure gear oils designed for industrial gear lubrication. They have better water tolerance, exhibiting good demulsification characteristics and low foaming tendencies, also provide rust and corrosion protection to metal surfaces.

These oils are formulated from high quality mineral oils and additives containing sulphur-phosphorus compounds to impart anti-wear and extreme pressure properties. PSO Gearled EP oils demonstrate improved thermal stability and oxidation resistance over conventional types.

Applications

  • PSO Gearled EP oils are primarily intended for enclosed gear sets operating under severe service conditions. They are recommended for gear boxes in heavy industries such as Steel Plants, Sugar and Cement industries etc.
     

Benefits

  • Excellent load carrying capability.
  • Excellent gearbox service life.
  • Protect against corrosion.
  • Excellent thermal and oxidation stability.
  • Good anti-wear performance.
     

Performance Standards

Meets the performance requirements of:

  • AGMA 9005-E02
  • DIN 51517 Part 3
  • ISO 12925-1 CKC/CKD
  • U.S. Steel 224
