Dry screw vacuum pumps

Hygienic 100% oil-free, air-cooled design

NOVADRY dry screw pumps offer maximum robustness and extended uptime with a hygienic 100% oil free design. NOVADRY’s innovative contact free design delivers zero oil emission and zero particle emissions for a clean process and high food safety.

Leybold’s low-maintenance dry screw vacuum pump, NOVADRY, do not require any oil or oil filter changes and have simple on-site maintenance that is set to revolutionize the market.

NOVADRY has a fully air-cooled design to ensure high standards of hygiene which goes further by using corrosion-resistant materials for pump components in contact with the process. This makes NOVADRY dry screw pumps, the vacuum benchmark for food safety and the vacuum pump of choice for food and packaging applications.

That give you a lower cost of ownership.

Vacuum as a key technology

The demands placed by manufacturers and consumers on the quality, shelf life and resource efficiency of food and packaging processes are constantly increasing. This applies even more to perishable products, for example: meat, dairy or fish. Vacuum is considered as an enabling technology, contributing significantly to optimizing food processing and packing. 

No oil, zero contamination

Food processing and packaging manufacturers struggle with vacuum pumps that emit oil contaminating the surfaces and the process. 100% oil free NOVADRY prevents such contamination. This increases safety in applications such as tumbling, filling, vacuum 

Air cooling reduces total cost of ownership

The air-cooled NOVADRY reduces operating costs by simplifying the installation and commissioning. The total life cycle operational costs of the NOVADRY are lower than that for oil-sealed vacuum pumps and other water-cooled dry pumps. NOVADRY’s air-cooled design not only lowers operational costs but also eliminates maintenance of water cooling circuit.

Broad range of applications

The NOVADRY stands out due to its robustness as it delivers full performance over the entire pressure range and life cycle and has a long uptime for simple as well as demanding food and packaging applications. With its robust self-draining design, it can easily handle humidity, as seen in packaging of cold products; powders, oils and greases as well as organic acids.

Proven in real life

NOVADRY has successfully proven its performance in a wide range of food applications such as tumbling, tray sealing, thermoforming, freeze drying and many others. In all applications, the food processing and packing manufacturers have benefited from NOVADRY’s fast cycle times and low final pressure.
