HP PARTHAN PG 320 is a high-performance synthetic gear lubricant formulated from premium-quality polyalkylene glycol (PAG) base oils combined with a specialized extreme pressure (EP) additive system. It is specifically developed for use in enclosed industrial gearboxes operating under severe load, high temperature, and continuous-duty conditions, where conventional mineral or synthetic hydrocarbon oils may fail to provide adequate protection. The advanced formulation ensures superior micropitting resistance, excellent load-carrying capacity, and outstanding wear protection, making it ideal for critical applications involving helical, bevel helical, planetary, and worm gears. Engineered to meet the demanding performance standards of DIN 51517 Part 3, DAVID BROWN Type G, and FLENDER SIEMENS micropitting test requirements, HP PARTHAN PG 320 ensures long-term gear reliability and smooth operation even under shock loading and extreme pressure environments. Its synthetic polyalkylene glycol base provides natural resistance to oxidation, varnish formation, and sludge build-up, resulting in cleaner system performance and reduced maintenance frequency. The lubricant’s low friction coefficient enhances gear efficiency, minimizes power loss, and helps reduce operating temperatures, contributing to extended equipment life and improved energy savings. HP PARTHAN PG 320 also offers excellent corrosion protection and outstanding demulsibility, ensuring effective separation of water and preventing emulsification that could lead to rust or gear surface damage. Its inherent thermal stability allows it to maintain consistent viscosity and performance throughout extended service intervals, even in the most demanding industrial environments. With its high micropitting protection, low foaming tendency, and enhanced anti-wear characteristics, HP PARTHAN PG 320 stands as a superior lubricant for high-performance gear systems requiring maximum durability, reduced downtime, and long operational life. It is recommended for use in heavy-duty gear units, precision industrial drives, and other enclosed gearbox systems across steel, cement, paper, and manufacturing industries where premium performance is essential.
