Notes:

  • The pump is essential for exhausting sealed vessels and can be used independently or as a forepump for booster, diffusion, and molecular pumps. It's also suitable as a holding pump in vacuum systems and pre-pumping for various types of pumps. Ideal for laboratory use due to its compact size, light weight, and quiet operation.
  • Operates continuously under atmospheric temperatures of 5°C to 40°C and intake pressure below 1230Pa. If the gas contains over 90% moisture, the gas-ballast valve should be open.
  • Do not operate the pump with the inlet port fully open to the atmosphere for more than one minute.
  • Not suitable for pumping oxidized, toxic, explosive, corrosive gases, or gases that react chemically with the pump oil or contain dust particles.
