Contact UsWhy Micro Air Pumps?
The design of sensitive equipment used for medical, gas sampling, and diagnostic applications is innovating at a rapid pace with a common theme: smaller without sacrificing efficiency or power. KNF micro air pumps can be customized for mounting orientation, motor size and placement, footprint, and head configuration to best suit the performance requirements. Ideally, these compact diaphragm pumps offer a solution for portable medical devices and gas sampling equipment. Shown here, the NMP 03 measures (length x width x height) 30.7 mm x 12.8 mm x 21.3 mm

The Best Compact Diaphragm Pumps
KNF Micro Diaphragm Pumps rely on the best options available within the modular system. Equipment manufacturers can select from wetted materials, such as elastomers EPDM and FFKM or thermoplastics like PTFE and PEEK, based on the requirements for chemical resistance. Additionally, the modular system allows for single or multiple head configurations as well as motor options. Material, motor and mechanical selections are finalized during engineer-to-engineer conversations and tested every step of the way, resulting in the best compact diaphragm pump for each unique application.

Spotlight: Vacuum Degassing Applications with Micro Diaphragm Pumps
Accuracy, quality, and throughput are key performance criteria that Analytical Laboratory, Inkjet, and Diagnostics equipment have in common. Requirements for accurate sample dosing, accurate detector readings, reduction of cavitation, the removal of unwanted gases, or the prevention of surface defects, all point to the need for vacuum degassing of liquid media.
