Busch RD series rotary vane vacuum pumps

Busch Vacuum Pumps has released a series of rotary vane vacuum pumps which claim energy savings of 20% over previous systems. Designed specifically for packaging machines, the RD series is based on the proven technology of R 5 rotary vane vacuum pumps, which have been stalwarts for decades in food production and packaging.

Technical optimisation of individual components has allowed energy consumption to be reduced significantly without affecting reliability and robustness. At the same time, the pumping speed of individual models at high vacuum levels has also been increased, which means reduced cycle times and lower energy consumption.

All components requiring maintenance are mounted on one side of the unit for easier access, thereby reducing downtime. The cooling air circulation has also been optimised. The cooling air outlet may be directed sideways or downward, depending on how the RD is built into the packaging machine. A gas ballast device fitted as standard equipment permits the extraction of humid air, making this vacuum pump suitable for the packaging of fresh meat and other moist products.
