Busch Mink claw vacuum technology for industrial vacuum generation offers the highest possible energy efficiency combined with low maintenance and a constant level of performance.

The sophisticated design of Busch claw vacuum technology allows Mink claw vacuum pumps to operate at extremely high efficiency levels, which has a positive effect on the pumping speed and energy consumption. In practice this means substantial energy savings for the same pumping speed when compared to conventional vacuum generators.

The contact-free operating principle of claw vacuum technology provides the additional benefit of nearly maintenance-free operation: none of the internal moving parts of the vacuum pump come in contact with each other, so components are not subject to wear. Servicing tasks such as inspection and replacement of worn parts are eliminated completely.

The proven, completely dry-running claw vacuum technology of Mink claw vacuum pumps allows them to run without operating fluids in the compression chamber. In practice this means no contamination of the pumped medium, and no environmental emissions. In addition, no costs arise for the purchase, replacement and disposal of operating fluids.

Mink claw vacuum pumps are air cooled, so no effort for the installation and maintenance of a cooling system is required. Their contactfree operating principle allows them to run extremely efficiently throughout the vacuum range and to deliver consistently high pumping speeds during their entire life cycle.

The outstanding reliability and long service lifetime of Mink claw vacuum pumps are also a result of the contact-free and dry compression. An intelligent sound insulation design allows Mink claw vacuum pumps to operate at low sound levels.

Technical specifications 
Mink claw vacuum pumps feature two claw-shaped rotors that move in opposite directions, mounted in a housing. The shape of these claw rotors extracts, compresses (in two stages) and expels air or gas. The rotors do not come in contact with each other or the housing, so no lubricants or operating fluids are required in the compression chamber. The minimal clearance between the rotors and the chamber housing optimizes the internal seal and ensures constantly high pumping speeds. An effective air cooling system guarantees optimal operating temperatures. A synchronizing gearbox maintains precise rotor timing. Mink claw vacuum pumps are driven by a directly flange-mounted asynchronous motor of efficiency class IE3.
