CHEMPOL 5022 Antiwear Hydraulic Additive Package


CHEMPOL 5022 additive is designed for the formulation of hydraulic oils. In addition to superior wear control, the product imparts rust and oxidation inhibition to the oil. CHEMPOL 5022 additive is a flexible package suitable for both premium quality and economic performance levels through an appropriate choice of dosage.


Dosage Recommended (WT%)

The recommended dosage for CHEMPOL 5022 additive is as follows:

  • 0.3 % to 0.5 %wt for minimum antiwear performance in high leakage systems.
  • 0.6 % to 0.75 %wt for economic hydraulic oil requiring wear and oxidation protection.
  • 0.8 % to 1.O %wt for premium hydraulic oils meeting major National and International Specifications.
  • 1.25 %wt to formulate hydraulic oil meeting requirements for long drain applications with increased load-carrying abilities.


  1. Outstanding wear protection, as manifested by performance in the 35VQ25 pump exceeding Vickers requirements.
  2. Good filterability.
  3. Security and confidence from a product with an extensive history of trouble—free performance worldwide.
