FL 10 is the newest liquid transfer pump to be added to KNF's extensive diaphragm liquid pump family. Powered by a solenoid-drive, the compact and durable FL 10 displaces fluid at a flow rate of 0 - 100 mL/min. Featuring unique valve technology, the KNF FL 10 transfer pump prevents uncontrolled flow and backflow of media when switched off. In addition, flow rate adjustments are fast and easy via signal frequency modulation. These features greatly simplify integration into your system, thus saving time and money. Moreover, the FL 10 diaphragm pump is self-priming and dry-run safe offering an exceptionally long-lifetime (10,000 hours or 1.8 billion strokes) of maintenance-free operation.


  • Check valve function in off-mode, eliminating uncontrolled flow and backflow   
  • Operates in difficult environments   
  • Leakage-free head parts   
  • Simple, linear flow rate adjustment for rapid testing and integration   
  • Fail-safe operation due to sealing between pump housing and linear drive    
  • Diaphragm technology for clean, gentle transportation of sensitive liquids   
  • Chemically resistant options available   
  • Expected maintenance-free lifetime of 10’000h   
  • Offers solid cost-saving potential
