KNF's NF25 diaphragm pump for transferring liquids features a high performance-to-size ratio

The KNF NF25 diaphragm pump for transferring liquids features a compact design and a high performance-to-size ratio. This micro-sized pump can handle liquids and gas-liquid mixtures at a flow rate up to 250 ml/min in <2.3 cubic inches.

A valve system ensures that the flow-to-motor speed curve remains linear to offer a solution for simple dosing applications.

The NF25 pump integrates an anti-cavitation chamber on the inlet side to promote quiet operation, higher flow and fewer air bubbles in the pumped liquid. Flows to 0.25 l/min, self-prime to 9 in. Hg and continuous pressure to 14.5 psig can be achieved.

Standard versions are offered with brush DC, ironless core DC or a four-wire brushless DC motor.

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. Their tight construction eliminates leakage, and corrosion-resistant materials protect against harsh media.

Standard accessories include shock mounts, hose and electrical connectors, valves, and filters.
