Features and benefits of the NOVADRY series
The series at a glance
The robust pump design tolerates water vapour, liquid droplets, organic acids and particles. The innovative belt drive and the self-draining design allow reliable operation even under difficult process conditions.
The NOVADRY was designed with high availability and long maintenance intervals in mind. Optimised belts and bearings simplify maintenance and reduce downtimes. The hygienic design makes the series particularly suitable for applications with the highest demands on food safety and process purity.
With the NOVADRY series, Leybold offers a powerful range of dry-running screw vacuum pumps developed for high process purity, reliable operation and low maintenance effort. The contact-free screw technology allows completely oil-free vacuum generation and is particularly suitable for applications with high demands on the purity of the vacuum. Thanks to its robust design and efficient dry-running technology, the NOVADRY series is a durable and reliable solution for demanding industrial and scientific vacuum applications.
Dry and oil-free
The Leybold NOVADRY series operates without oil in the compression chamber and thus provides a clean, contamination-free vacuum. This is a particular advantage for sensitive processes with high demands on process purity.
High process purity
The dry-running screw technology prevents contamination of the conveyed medium by oil or lubricants. This makes the series particularly suitable for demanding applications in research, analytics, coating and industrial vacuum technology.
Compact and flexible solution
The NOVADRY series combines a compact design with reliable vacuum performance and is suitable for a variety of applications that require dry, oil-free vacuum and high operational reliability.
Operating principle
The Leybold NOVADRY series works according to the principle of dry-running screw vacuum technology. Two counter-rotating screw rotors move inside the pump housing without contact and continuously convey the gas drawn in through the compression stages. In the process, the gas is compressed step by step and then expelled through the outlet.
As the NOVADRY series operates dry and completely oil-free, the conveyed medium does not come into contact with oil or lubricants in the compression chamber. The technology thus allows particularly clean, contamination-free vacuum generation and is ideal for applications with high demands on process purity.
The robust design and the contact-free screw principle allow reliable, durable and low-maintenance operation. The dry-running technology also reduces the risk of process contamination and makes the pumps particularly suitable for sensitive applications.
The NOVADRY series is suitable for numerous industrial and scientific applications that require dry, oil-free vacuum, high process purity, reliable performance and low maintenance effort.
