Finger Pump
This is a still representation and possibly also a low-resolution image of a fully animated pump.
     Finger pumps push a series of rods against a flexible tubing in sequence, forcing fluid along the tube. In this pump the fluid moves from left to right.
     Since nothing but the tube actually touches the fluid, the fluid can be kept clean so this pump is often found in medical applications, pumping blood or other fluids.
     The individual fingers can be operated by a rotating camshaft above them, by individual solenoids electronically actuated in sequence, or by other methods.
