Concept Features Areas of use

KNF micro diaphragm liquid pumps are based on the principle of the oscillating displacement pump which is remarkably simple in design. The circular power from the motor is converted into vertical move- ment by an eccentric. This motion is then transferred to a diaphragm by means of a connecting rod which, in conjunction with an inlet and outlet valve, creates a pump- ing action.The NF5 liquid pump can be mounted in any position. It delivers up to 70 ml/min and will operate against pressures of up to 10mWg. Small and powerful
The versatility of KNF pumps allows a wide field of applications to be covered. Over many years our pumps have proved themselves in the following areas: Micro design and maximum performance resulting from built-in technology are the outstanding characteristics of these prod- ucts. Analysers Self-priming
• Medical / pharmaceutical • Environmental / water treatment • Food / toxicology Sophisticated diaphragm technology and precise valve structures enable perfor- mances of 4mWg suction or 10mWg pressure. Laboratory
• Filtration • Chromatography Extreme chemical resistance
The use of the materials PPS and EPDM for the parts which come in contact with the liquid allows many neutral or corrosive liquid to be pumped. Cleaning industry
• Cuvette cleaning • Sterilisers • Industrial washing machines Dry running, durable and main-tenance free Printing
The carefully considered design of these pumps allows them to be run dry and ensures safe operation and a long life even under the most severe conditions. • Ink jet printing • Photographic / film developmentOther applications for micro-diaphragm liquid pumps include: fuel cells, hydrogen generators, CD coating, dental technology, textiles and many more.
