Vacuum Pumps

Functional principle vacuum pump

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

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

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 maintenanceas well as high vacuum, for handling air-tight workpieces

Water-ring pumps

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
