Micro-liquid dosing pump for small quantities

KNF Neuberger has developed the NF5KTDC-B4, a micro diaphragm pump which makes it possible to dose accurately small quantities of liquid in the same way as more expensive conventional full-feature peristaltic dosing pumps.

The pump works with an 0-5 volt control signal which controls the brushless motor's speed and flow rate between 5 and 70 ml/min. A linear rpm/ response is an indication of the system's precision and repeatability. An integrated pulse generator enables the operator to monitor the motor speed of the pump, keep track of the liquid dosage and therefore calibrate the pump.

The pump, including 12 to 24VDC input range motor, is compact (31 x 26 x 28 mm), has a service life of over 10,000 hours, and requires less than 1 watt of power. It is suitable for pumping and dosing both neutral and corrosive liquids. It has a suction height of 13 ft. water and will pump back pressures up to 14 psig.
