DC Peristaltic Fluid Pump [6V , 12V , 24V]

Descriptions:
This product is a kind of peristaltic pump that is a type of positive displacement pump used for pumping a variety of fluids, they are also commonly known as roller pumps.
The pump is basically a geared down DC motor, so it has a lot of torque. Inside the pump is a 'clover' pattern of rollers. As the motor turns, the clover presses on the tube to press the fluid though. The pump does not need to be primed and in fact can self-prime itself with water a half meter with ease. You can PWM the motor to speed up or slow down the flow rate and if you connect the motor the other way it will move fluid the other direction.
