double stage vacuum pump is a type of vacuum pump designed to create a higher vacuum level than single-stage pumps. It consists of two sets of pumping mechanisms, typically in series, which work together to remove air and other gases from a sealed system more effectively.

Key Features:

  1. Two Stages of Compression:
    • In the first stage, the pump compresses gas to a lower pressure.
    • In the second stage, it further reduces the pressure, enabling deeper vacuums.
  2. Higher Vacuum Level:
    • Double-stage pumps can achieve lower absolute pressures (down to 0.001 mbar or lower), making them ideal for applications requiring ultra-high vacuum levels.
  3. Applications:
    • Commonly used in scientific laboratories, refrigeration, air conditioning, and industrial processes where high vacuum performance is needed.
