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.
