Micro pump unit with osmosis pump - IBP Series

Under development

Micro pump unit with osmosis pump


This pump is based on the electroendosmosis principle and offers outstanding features such as:

  • no pulsations
  • quiet operation
  • small size
  • lightweight
  • low power consumption
  • high pressure up to 10 bar

Linear control of flow rate through the change in voltage.

Optionally battery operable. (Voltage step-up circuit is required)

Internal strcuture

IBP internal structure

This pumping unit uses an Electroosmotic pump as the pressure source. As shown in the figure, the diaphragm is pressurized from the top by the working fluid, and thus, the liquid to be delivered is pumped out. Suction is also possible by reversing the polarity of the applied voltage when ethanol is used as the working fluid. (Optional Feature)
