Their tight construction eliminates leakage and corrosion-resistant materials protect against harsh media.
NF25 pumps can serve as reliable replacements for peristaltic, gear, syringe, or piston pumps and can be installed in any position close to the desired pumping function.



Trenton, NJ - 12/17/9 - The new KNF NF25 diaphragm pump for transferring liquids introduces an ultra-compact design and the highest performance-to-size ratio of any liquid pump in the marketplace. Features include:  

  • The ability to handle liquid and gas-liquid mixtures at a flow rate up to 250 ml/min in <2.3 cubic inches. 
  • A patented valve system that ensures that the flow-to-motor speed curve remains linear.
  • An integrated anti-cavitation chamber on the inlet side to promote quiet operation, higher flow, and few air bubbles.
  • Flows to 0.25 l/min.
  • Self-prime to 9 in. Hg.
  • Continuous pressure to 14.5 PSIG.
  • Availability with brush DC, ironless core DC or a 4-wire brushless DC motor (recommended for longer and maintenance-free service life and advanced control possibilities).
  • Standard accessories including: shock mounts, hose and electrical connectors, valves, and filters.
