Schmalz - The Company 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
Vacuum Knowledge 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).

Vacuum Suction Cups 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
Special Grippers Typical areas of application Functional principle vacuum pump

• As central vacuum generation in gantry handling systems
Vacuum Grip- ping Systems • In manual vacuum handling systems
• In packaging machines
