KNF debuts Type NF1.25 high-pressure micro diaphragm pump

The KNF Type NF1.25 micro diaphragm pump offers a high-pressure solution for dosing or transferring liquids or liquid-gas mixtures at flow rates up to 300 ml/min. This small and powerful pump is engineered to operate either intermittently or continuously against pressure up to 6 barG (87 psig) over the pump’s entire lifetime. Versions can be specially developed to handle pressure up to 10 barG (145 psig).

Type NF1.25 pumps integrate a patented valve system and benefit from sophisticated diaphragm technology to achieve high levels of efficiency. OEMs can choose from a wide selection of motors, including iron core DC, ironless core DC, or brushless DC (BLDC). The BLDC models can be supplied with simple two-wire operation or with four wires enabling advanced tachometer output and speed control input and a highly linear control curve (flow rate vs. control voltage) allowing for use in closed-loop systems. A wide range of standard voltages and frequencies can be specified.
