Abstract

A micropump combining reciprocating motion of a magnetic ball covered with magnetic fluid and diffusers working as valves was investigated experimentally in this study. The reciprocating motion of the magnetic substance pushes water in order to transport it. The diffusers with different divergence angles serve to pump water in net one direction. In the present micropump experiments, the maximum flow rate achieved with minimum backpressure was 3.89 μl/min and the maximum pressure head achieved was 42.4 mm water.
