Abstract

In this paper, specially designed constant and rippleless flow miniature planar pumps with electromagnetic driven actuators were developed. A novel approach in this project was the incorporation of electronic control of the pumps to achieve an accurate four phase pumping process. Four pumps were interconnected as a single pumping module according to the principles of rippleless pump. The miniaturised 4- phase pump has been evaluated and has the following specifications: suitable for liquid, self-priming under the applied conditions, low power consumption (about 10 watt), DC power supply (7.5V to 11 volts) square wave signal, flow rate 1.5 to 3.5 ml min-1, chemical inteness, low maintenance, and low cost. The miniaturised electromagnetic pumps described in this reseach were purpose-designed for the flow injection analysis measurement. However, it is possible they could also be employed in other microanayticall applications such as U.TAS. Keywords- Miniaturised pump, micropump, Electromagnetic actuation, sensor, FIA, U.TAS
