1. The fluid passes through the pump and the liquid enters the suction port between the rotor (larger external gear) and idler (smaller internal gear). The arrow indicates the direction of the pump and liquid.

2. Liquid flows through the pump between the teeth of the "gear internal gear" principle. The crescent shape separates the liquid and acts as a seal between the suction port and the exhaust port.

3. Now, before forcing the liquid out of the discharge port, the pump head is almost full. The intermeshing gears of the idler and rotor form a locking cavity for the liquid, thus ensuring volume control.

4. The rotor and idler teeth are fully meshed to form a seal equidistant from the discharge and suction ports. This seal forces liquid to flow out of the discharge port.
