TFS Takasago Fluidic Systems

EOP-Driven Micro Pumping Unit


Features

  • Employs electroendosmosis – generates no pulsation and no operation sound.
  • Smaller and lighter than a conventional syringe pump or pressure-driven pump.
  • Low power consumption – can be operated using batteries.
  • Easily adjustable flow. Linearly proportional to applied voltage.



Internal Structure (Image)

This pump unit utilizes an electro-osmotic pump (EOP) as the pressure source. The liquid to be delivered is discharged when pressure is applied to the diaphragm by the working liquid (ethanol) as it is pumped from the left to the right of the EOP in the picture. Suction is also possible by reversing the polarity of the applied voltage.
