Product Description
TSINGDOC WeiLi vacuum pump lubricant is formulated from high-quality, low-volatility base oils and fortified with high-performance additives including antioxidant, anti-wear, demulsifier, antirust agents, and more. Precision-engineered with an advanced formulation, it is suitable for lubricating vacuum pumps.
Features and Benefits
1. Delivers exceptional chemical stability and oxidation resistance, ensuring a long service life and inhibiting deposits formation.
2. Extremely low vapour pressure prevents degradation of the vacuum due to oil evaporation.
3. Excellent air release properties provide efficient pump operation.
4. Balanced viscosity enables rapid pump cold starts. Excellent seal performance ensures low operating temperature.
5. Superb demulsibility helps separate the lubricant from water rapidly, thereby preventing emulsion generation.
6. Robust wear protection in starts and critical states.
Applications
Suitable for sealing and lubricating mechanical vacuum pumps of various capacities, and for lubricating gear transmission systems of supercharge vacuum pumps.
