Move fluid safely from here to there with this very nice Peristaltic Pump that works with 5V or 6V power. Unlike most liquid pumps, this is a peristaltic type - the pump squishes the silicone tubing that contains the liquid instead of impelling it directly.
One of the two DC motor leads for the peristaltic pump motor. Adafruit describes the pump as a geared-down DC motor and says reversing the motor connection reverses flow direction.
The other DC motor lead for the peristaltic pump motor. Polarity is reversible for flow direction according to the Adafruit product description.
Fluid path through the silicone tubing. The source describes a peristaltic pump where rollers press the tube and the pump never touches the fluid.
