The NF25 diaphragm pump can handle liquid and gas-liquid mixtures at a flow rate up to 250 ml/min in <2.3 cubic inches. A patented valve system ensures that the flow-to-motor speed curve remains linear to offer an ideal solution for simple dosing applications. The NF25 pump additionally integrates a unique anti-cavitation chamber on the inlet side to promote extremely quiet operation, higher flow, and fewest air bubbles in the pumped liquid. Flows to 0.25 l/min, self-prime to 9.0 in. Hg, and continuous pressure to 14.5 psig can be achieved. Standard versions are offered with brush DC, ironless core DC, or a 4-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.
