Contact-free operation means no wearing parts.

With the new Mink MV series, Busch Vacuum Pumps and Systems, Virginia Beach, Va., has reportedly succeeded in developing claw vacuum pumps that have a significantly lower noise level than comparable pumps on the market. They are also said to be extremely compact and efficient. The new series will debut at K 2016 this month.

The new series operates in the same way as the previous series (that is, according to the dry and contact-free claw principle). Therefore, no operating fluid is required in the compression chamber, which means all associated maintenance work such as oil and filter changes is eliminated. Wear is said to be eliminated, as the contact-free operation means no wearing parts have to be replaced.

Mink claw vacuum pumps are used to generate the vacuum required for pneumatically feeding material into primary processing machines. In principle, these vacuum pumps are also suitable for use in centralized vacuum systems. What’s more, for the past 20 years Mink claw vacuum pumps have been used for degassing melt during extrusion.
