KNF Neuberger recently introduced a new swing-piston pump designed to compress air, generate vacuum, and transfer air. The pumps of the new NPK 25 series are dry running pumps. They generate overpressure of 5 bar (DC version: 4 bar) and transfer 30 liters of air per minute at atmospheric pressure (DC version: 25 liters/minute). Ultimate vacuum is 180 mbar absolute.

These pumps are characterized by their small size, low noise and low vibration during operation, and an outstanding price- performance ratio. They are maintenance-free, have a very long service life, and can be operated from any installation position. The sealed swing piston moves media without oil to prevent contamination.

These pumps are ideal for use in devices and apparatus for medicine, food and environmental engineering, as well as production engineering and pneumatics.

Newly developed model NPK 25 is just the latest addition to this manufacturer's line of swing-piston pumps. The company manufactures swing-piston pumps with specifications ranging from 3.3 to 78 liters per minute (at atmospheric pressure), ultimate vacuum down to 80 mbar absolute, and overpressures up to 7 bar.
