HP PARTHAN EP 680 is an ultra-high-viscosity industrial gear oil formulated for slow-speed, high-load gear applications that require maximum film strength and anti-wear protection. The product’s high-quality base oils and advanced EP additive package provide exceptional resistance to scuffing, wear, and metal fatigue under extreme operating pressures. Its strong oxidative and thermal stability ensures clean operation and long lubricant life, even under continuous heavy-duty service. The oil’s anti-foam, anti-rust, and demulsifying properties protect internal components from oxidation, corrosion, and moisture damage, ensuring reliable gear performance in all conditions. HP PARTHAN EP 680 is designed to reduce frictional losses and operating temperatures while maintaining consistent lubrication across a wide temperature range. It is ideal for use in large gearboxes, cement kilns, ball mills, mining conveyors, and steel rolling equipment that operate under severe load and high ambient stress.
