Optimized Solutions for Each Application

With a close-knit network of 60 Busch companies in more than 42 countries and agencies worldwide, Busch has a global presence. Drawing on their many years of experience, the specialists from Busch will be happy to advise you on all areas of plastics processing for which vacuum is required. These could range from simple applications in the field of handling, to individual degassing systems for extruders or central vacuum supply systems. With the wide selection of products available from Busch, you can always find the most technically suitable and cost-effective vacuum generator whatever the application.

Busch has developed Plastex vacuum systems specially for melt degassing with extruders. Essentially these modular vacuum systems consist of one or several vacuum pumps, the separation technology that filters out or condensates the discharged gases and steam, and the control technology.

With the dry-compressing Mink claw vacuum pump, the engineers at Busch are offering us another highly cost-effective and operationally reliable vacuum generator, available in many sizes and varieties, which meets the requirements of the plastics industry exceptionally well. Oil-lubricated rotary vane vacuum pumps, dry screw vacuum pumps, liquid ring vacuum pumps and side channel blowers are further vacuum generators that can be used for processes in the plastics processing industry.

No matter what the requirements are in terms of vacuum supply for your process, Busch will always offer you the most economical solution for your specific needs – from a simple blower to a complex vacuum system complete with a control system. Please get in touch.

From a Standard Product to an Individual Solution for Every Application

We offer you a wide selection of technologies for vacuum generation in the field of plastics processing.

Plastex extruder degassing systems
Plastex degassing systems are standardized modules for degassing the vapours in the extruder screw zone. Depending on the process, extruder and material, Mink dry claw vacuum pumps or Dolphin liquid ring vacuum pumps are used. In the case of large throughputs, COBRA dry screw vacuum pumps are installed in Plastex vacuum systems. Puma or Panda vacuum-boosters are used as boosters.

Combi extruder degassing systems
Combi systems are individual vacuum technology solutions for melt degassing during extrusion. They are designed by Busch engineers in accordance with the relevant extruder/process. The same components are used as on Plastex vacuum systems.

Mink dry claw vacuum pumps
The dry Mink claw vacuum pumps impress thanks to their high level of cost-effectiveness. Owing to their dry and contact-free operating principle, these vacuum pumps are extremely energy-efficient, operationally reliable and virtually maintenance-free. Mink vacuum pumps are therefore the ideal components for pneumatic conveying or degassing.

COBRA dry screw vacuum pumps
COBRA screw vacuum pumps are dry-compressing and achieve high pumping speeds and vacuum levels. They are used in Combi and Plastex vacuum systems.

R 5 oil-lubricated rotary vane vacuum pumps
The oil-lubricated R 5 rotary vane vacuum pumps are the standard vacuum pumps almost throughout the industry. Thanks to their reliability and robustness they can be used in virtually all areas of plastic processing.

Samos side channel blowers
Samos is the range of maintenance-free vacuum and overpressure blowers from Busch. They are available in many different sizes and performance classes and are very well-suited to smaller pneumatic conveyor systems, both for suction conveying and for pressure conveying.

Tyr rotary lobe blowers
Tyr are high performance generators for vacuum and overpressure which set new benchmarks in performance, compactness and noise minimization. They are the perfect solution for generating vacuum or overpressure for the transport of plastic pellets and for mostly all handling applications in plastic processing.
