How Claw Vacuum Pumps Work: Applications and Benefits

An essential piece of equipment on modern production lines, claw vacuum pumps are establishing themselves in 2026 as the key to efficient, clean, and cost-effective industrial production. From plastics to the food industry, their ability to deliver a consistent vacuum, without oil or friction in the compression, is transforming flow management and process optimisation.

 

Whether ensuring the integrity of food products, securing pneumatic conveying, or improving the reliability of pick-and-place automation, these pumps embody innovation while offering reduced maintenance.

 

New generations combine energy efficiency with robust components, paving the way for predictive maintenance and high adaptability to demanding environments.

 

In brief:

·        Oil-free, contact-free technology: for clean processes and simplified maintenance 

·        Variable frequency drive: energy savings 

·        Industrial applications: plastic extrusion, food processing, plastics industry, sanitation, printing, and mechanical industry 

·        Key advantages: robustness, easy one-to-one exchange of single pumps, energy efficiency, easy integration into centralised systems, and low operating costs 

 

Technology, operation, and industrial advantages of claw vacuum pumps

 

Claw vacuum pump technology continues to expand across production lines, driven by the need for cost savings and cleanliness. The operating principle is based on two synchronised claw rotors that rotate without contact and without internal lubrication in the compression.

 

This principle enables dry air compression, drastically reducing wear, operating temperature, and, above all, environmental impact. The absence of oil in the extracted air is a decisive factor in the food industry, pharmaceutical production, and plastics processing.

 

Automation is also part of this dynamic. Variable-speed versions precisely adapt pump performance to actual process demand, maintain a constant vacuum level through pressure control, and provide additional capacity when required. Especially under fluctuating operating conditions, this demand-based control can significantly reduce energy consumption and operating costs, while soft starting limits the starting current.

 

Industrial applications of claw vacuum pumps: plastic extrusion, pneumatic conveying and more

Claw vacuum pumps demonstrate their full potential through the breadth of their applications. From conveying plastic granules in the plastics industry to handling vacuum-packed food packaging, the versatility of this technology gives it a strategic role in highly automated sites.

 

For example, a paper-cutting SME can use a centralised Becker claw pump system to supply its converting machines, eliminating oil vapor in the exhaust gas and reducing workshop noise level by relocating them to a separate room in a rack system.

 

Overview of uses: food industry, plastics, printing, and mechanical engineering

In the food industry, the requirement for a clean and stable vacuum is essential, ensuring the safety of packaged products. Dry claw solutions are also widely used in:

 

Plastic extrusion, degassing, and cooling - dry, oil-free compression minimizes the risk of process contamination	Pneumatic conveying of powders and grains	Printing and cutting processes where a centralized vacuum system provides a stable vacuum supply while reducing noise at the machines	Vacuum sewer and sanitation systems for efficient wastewater transport

 

Other sectors also benefit from these pumps: Automated Handling (Pick-and-Place), CNC Machines, Wood Drying, Tobacco Industry, etc. This wide range of applications highlights the technological strength of claw solutions.

 

Integration into centralised systems and optimisation of vacuum processes

The integration of claw vacuum pumps into centralised vacuum systems allows collective management of energy demand and vacuum levels across multiple production lines. Industrial users benefit from continuous monitoring, resource sharing, and reduced maintenance thanks to the modularity and redundancy of the system.

 

Centralized uses	Expected benefits
Food packaging networks	Stable vacuum supply, reduced contamination risk, and high system availability
Pneumatic conveying	Optimised flow, reduced consumption
Textile/printing plants	Vacuum regulation, reduced noise at the machines through centralized vacuum generation

The combination of intelligent electronics with these centralised networks opens new possibilities for predictive maintenance and remote management of installations.

 

Advantages of Becker claw vacuum pumps: oil-free operation, efficiency, and durability

Becker claw vacuum pumps stand out for their simplicity: oil-free operation and no mechanical contact, minimising maintenance requirements. Their design ensures high durability, even in dusty or corrosive environments.

 

They are particularly well suited for pick & place handling systems and centralised vacuum systems in printing plants, enabling continuous production cycles with some of the lowest operating costs on the market.
