Vacuum Pumps


Vacuum pumps include an eccentrically mounted impeller with lamellas (A) which are pressed against the walls of the housing by centrifugal force and thus provide a seal. As the impeller rotates, the size of each chamber (B) varies. As the chamber becomes larger, the air in it expands and the pressure drops, resulting in a partial vacuum. The air is drawn in through the inlet (C), compressed and ejected through the outlet (D).

Due to their high compression factor, pumps generate a very high vacuum and according to the type, have a very high suction capacity.

Advantages of vacuum pumps

  • High vacuum with high evacuation volume
  • Central vacuum generation

Typical areas of application

  • As central vacuum generation in gantry handling systems
  • In manual vacuum handling systems
  • In packaging machines

We distinguish between three basic types of vacuum pumps:

Dry-running pumps

  • Universal vacuum pumps requiring little maintenance
  • Used mainly as central vacuum generator in large gripping systems for handling air-tight workpieces

Oil-lubricated pumps

  • Vacuum pump with extremely high vacuum level (up to 95% vacuum)
  • Used in handling systems with an emphasis on low noise and low maintenance well as high vacuum, for handling air-tight workpieces

Water-ring pumps

  • Vacuum pump requiring little maintenance with internal water cooling for handling air-tight workpieces
  • Used especially in areas with high demands on ambient air (e.g. packaging in the food industry
