The first vacuum pump with hygienic design in the world has been introduced by Busch Vacuum Pumps and Systems. This new rotary vane vacuum pump was developed specially for foodstuffs packaging with tray sealers and thermoforming machines, and is designed to be cleaned using steam jets and conventional detergents.

The unit surfaces are smooth and slightly inclined, allowing water and detergent to drain away after cleaning to leave a residue-free finish.

Initially only the models RAH 200 A and RAH 300 A with pumping speeds of 200 and 300 m³/h will be available. The new vacuum pumps are based on the proven oil-lubricated Busch R 5 rotary vane vacuum pumps, which have been installed in many packaging machines and remote centralised vacuum systems. The rotary vane technology of the new hygienic vacuum pumps guarantees a permanent vacuum of 0.1 mbar and high pumping speeds for the entire range between atmospheric and ultimate pressure, allowing rapid evacuation and short packaging cycle times. The vacuum pumps are water cooled, preventing heat emissions to the packaging machine and cooled packaging area. The packaging area temperature (a legal requirement, and important for food packaging operations) remains unaffected. In addition, cooling energy is saved. A water cooled motor may be ordered as an option to further reduce heat emissions. The heat energy from the cooling system can be reused elsewhere, resulting in an additional improvement to the energy balance of the vacuum system. The water supply is easily connected to the packaging machine cooling system. Installation of the unit is a simple process due to its compact dimensions and flexible vacuum connector.
