Product description

Vacuum pump oil is formulated from deeply refined lubricating oil fractions with selected additives. It offers good sealing, water resistance, anti-corrosion, and lubrication performance. It resists degradation under prolonged high-temperature exposure to air, resins, and chemicals, reducing harmful deposits and extending oil change intervals. It forms an effective anti-corrosion film on metal surfaces to prevent system corrosion from吸入 corrosive gases and moisture. It rapidly separates water from the oil to achieve the required vacuum level. Low vapor pressure prevents oil from backflowing into the vacuum system, ensuring sufficient ultimate vacuum.

  • Mainly used for sealing and lubricating various types of mechanical vacuum pumps
  • Suitable for reciprocating booster pumps and mechanical booster pumps
  • Suitable for oil-sealed mechanical vacuum pumps and diffusion vacuum pumps
  • Recommended for crafts, ceramics, chemicals, and other industries
