The Yildiz Pump’s “gear within gear” principle, consisting of only two moving parts, ensures reliable and efficient operation. The secret to the success of positive displacement Yildiz Pompa is the displacement that occurs when the liquid completely fills the space between the rotor and the gear of the idler gear.

As with all gear pumps, the only factor limiting the performance of the Yildiz Pumps is the cleanliness of the pumped liquid. At each revolution of the pump shaft, a certain amount of liquid enters the pump through the suction port and this liquid fills the gap between the rotor and the idler gear.

The crescent on the pump cover regulates the flow of the liquid moving towards the outlet opening. The idler gear rotates on a shaft supported by the pump cover by carrying the liquid between its gear and the inner surface of the crescent. The rotor gear moves between the pump casing and
the outer surface of the crescent and is connected to the pump shaft.

The yellow colored portion at side indicates the liquid as it enters the suction port area of the casing and the area between the rotor teeth and corresponding concave area between the idler teeth. The two black arrows indicate the pump rotation and progress of the liquid.

Notice the progress of the liquid through the pump and between the teeth of rotor idler gear. Also, note how the crescent shape on the head divides the liquid and acts as a seal between the suction and discharge ports.

This illustration shows the pump in a nearly flooded condition just previous to the liquid being forced into the discharge port area. Notice how the gear design of the idler and rotor form locked pockets for the liquid to guarantee absolute volume control.

The view shows the pump in a completely flooded condition and in the process of discharging the liquid through discharge port. The rotor and idler teeth mesh, forming a seal equidistant between the both ports, forcing liquid out the discharge port.
