  • What is the difference between Oil-free Scroll Vacuum Pumps, oil-sealed rotary pumps and water seal vacuum pumps?
    Oil-free Scroll Vacuum Pumps can always maintain a clean vacuum and working condition, since they do not use lube oil nor seal water inside, resulting in no back diffusion of lube oil and seal water. Oil-free vacuum pumps can save oil cost, labor cost of replenishing oil, and industrial was...

  • Rotary Vane product maintenance
    Rotary Vane product maintenance Rotary vane vacuum pump (referred to as the rotary vane pump) is a mechanical pump seal. Its working pressure in the range of 101325 ~ 1.33 × 10-2 (Pa) belonging to the roughing pump. It can be used alone or as a pre-pump and other high vacuum or ultra-...

  • Vacuum pump cavitation
    Vacuum pump cavitation is caused by vaporization of water, that is to say the water vapor vaporization process of state from liquid transformation. Pump cavitation phenomena will seriously affect their life time and also influence their production efficiency and production quality. When wa...
