DFRobot Gravity - wired pump - peristaltic

Module connecting the PPM motor driver with a peristaltic pump. The control signal is compatible with a signal controlling the servos that can be used with different boards, such as Arduino, Raspberry, micro:bit, to be able to freely adjust the speed and direction of the flow. The pump is powered with the voltage of 6 V.

Power consumption of the motor is 5 W, therefore it is recommended to use a separate power source. The USB port can only provide 2.5 W.

The peristaltic pump is characterized in that that the liquid is pushed through a flexible cable using the serriform strap, the serriform shaft, rolling rollers or rotor moving on the wire so the pumped liquid has no contact with elements of the pump, and it is completely sealed, because of this, it is used in medical devices or for pumping aggresive liquids.

The conductive pump as a type of dose pump, can be used for quantitative delivery.
