Description
Special Features
Certain Industrial Gear Units in are exposed to high-load/low-speed conditions which can lead to the breakdown of the lubricating film that is normally required for a long bearing life. This problem was identified by the R&D of Hindustan Petroleum Corporation Limited and premium mineral grade oil PARTHAN EP MA series has been developed to counter the micro-pitting problems.
PARTHAN EP MA has been specially formulated with new generation extreme pressure additive which is chlorine free and offers long term protection against rust and corrosion while simultaneously keeping gear parts clean and also ensuring good filterability. Premium antioxidants provide long service life in applications.
