Applications

Reliable Vacuum for a Wide Range of Applications Even Under Harsh Conditions

Vacuum packaging
R 5 vacuum pumps are renowned throughout the world as the vacuum packaging pumps par excellence. Vacuum packaging helps to extend shelf life of fresh food considerably and has therefore become indispensable today. In particular, the extraction of oxygen plays a decisive role. This method prevents oxidation processes, preserving not only quality, texture and flavour of the packaged product but also its nutrients, vitamins and taste. Furthermore, aerobic bacteria multiply only very slowly or not at all. Dry foods can be protected against moisture by means of vacuum packaging. MAP (modified atmosphere packaging) is mainly used for fresh meat, fish or convenience food. Atmosphere in the packaging is replaced by a gas mixture to maintain optical appearance, freshness and flavour.

Plastics processing
Due to their robustness and reliability R 5 RA rotary vane vacuum pumps are used in practically all sectors of plastics processing. In addition to pneumatic conveying, important application areas for R 5 RA rotary vane technology include plastic degassing in extruders, evacuating injection moulds, and plastic sheet thermoforming.

Hospitals and healthcare facilities
R 5 RA rotary vane vacuum pumps provide vacuum to the treatment rooms of hospitals and other healthcare facilities. They are mostly installed centrally, and supply vacuum to medical appliances via a pipe network. The high availability of R 5 RA vacuum pumps contributes to improved safety in this sensitive sector.


Meat processing
R 5 RA rotary vane vacuum pumps are well-established in all meat processing applications like vacuum fillers, mixers, cutters and tumblers. They evacuate air from fresh meat products and avoid that they come into contact with oxygen, thus increasing shelf life and improving food quality.

Handling and lifting
For decades, R 5 RA rotary vane vacuum pumps have been in operation in many handling and lifting applications – from simple lifting devices to pick-and-place systems and robots. They are used for safe and reliable moving of all sorts of materials, such as cartons, barrels, planks of wood, steel, glass or plastic. With R 5 RA vacuum pumps even objects with delicate, rough and irregular surfaces can be transported carefully and reliably.

Central vacuum systems
R 5 RA rotary vane vacuum pumps are the perfect individual vacuum modules in a centralized vacuum supply. Providing central vacuum systems is an area in which Busch has gained worldwide experience over many decades. Thanks to the accumulated know-how from thousands of installations Busch can always provide the best vacuum solution meeting the specific requirements of each customer.
