The company Dr.-Ing. K. Busch GmbH recently presented its new generation of R 5 vacuum pumps for the first time. These vacuum pumps can be used in all kinds of packaging machines, from small chamber machines to large-scale roller machines and make significantly shorter packaging cycle times possible.

These shorter packaging times have been made possible by the greater vacuum achieved by the vacuum pumps. This also makes the suction capacity achieved at packaging vacuum up to 50 percent higher than with previous rotary vane vacuum pumps. Busch offers these new R 5 vacuum pumps in a wide range of sizes from 25 to 1600 cubic metres per hour suction capacity. The outer dimensions and all the connection dimensions are unchanged from the previous version.

Oil separation has also been improved with all the design sizes, through the internal geometry of the oil mist separator and the permanent advanced development of filter technology. Original Busch filter elements have been matched exactly to the respective vacuum pump size and guarantee the maximum degree of separation by taking the latest developments in filtering technology into account. R 5 rotary vane vacuum pumps from Busch can be used both for long-term operation and at short intervals. These tried-and-trusted and sturdy vacuum pumps have been in use for decades all over the world, wherever meat and cold cuts are processed and packed. R 5 vacuum pumps from Busch set industrial benchmarks in many other applications, too.

The Mink claw vacuum pump will be presented by Dr.-Ing. K. Busch GmbH at Ligna 2007. This vacuum pump is now available with a volume flow rate of 70 to 500 cubic metres per hour and thus fully covers the power requirement for applications in wood machining. Mink vacuum pumps fundamentally differ from conventional vacuum pumps in that they operate without contact and with zero wear. Due to their contact-free operating principle no oil is required as an operating fluid. For the operator this means: No replacement of worn parts, no oil changes and no shutdown periods. The maintenance work on a Mink vacuum pump is restricted to cleaning the intake filter and changing the operating oil after 20.000 operating hours. Because of its high efficiency the Mink is essentially more economical to operate than all other vacuum pumps. This leads to potential energy savings up to 60% relative to a dry-sealed rotary vane vacuum pump. Mink vacuum pumps can be driven with a frequency-regulated motor. This provides further energy savings, since the vacuum pump only draws the current from the mains that is actually required. Due to the minimal maintenance work required the maintenance costs are reduced drastically relative to other vacuum pumps.

Mink vacuum pumps from Busch are ideal vacuum creators for clamping tasks on processing machinery and on component equipping machines where a reliable and safe vacuum is imperative.
