Diaphragm pump

March 9, 2012
The new Type NF1.25 diaphragm pump handles dosing or transferring liquids or liquid-gas mixtures at flow rates up to 300 ml/min.

The new Type NF1.25 diaphragm pump handles dosing or transferring liquids or liquid-gas mixtures at flow rates up to 300 ml/min. The pump is engineered to operate either intermittently or continuously against pressure up to 87 psig. Versions can be developed to handle pressures up to 145 psig.

The pump’s have a patented valve and sophisticated diaphragm technology. Users can choose from a wide selection of motors, including iron-core dc, ironless-core dc, or brushless-dc (BLDC) versions. The BLDC models can be supplied with simple two-wire operation or with four wires for advanced tachometer output and speed control input, and a highly linear control curve (flow rate versus control voltage) for use in closed-loop systems.

These self-priming pumps can run dry, require virtually no maintenance, and offer chemical resistance by using PP, PTFE, EPDM, and FFMP for components that contact the pumped medium.

Specialized accessories are available, including an antivibration mounting plate that can reduce vibration levels and audible noise. Pumps can be mounted in any position.
