The Magnetically Driven Internal Eccentric Gear Pump is a reliable and efficient solution based on the simple “gear within gear” principle. The rotary and idler gears in the pump head create cavities between their teeth, achieving positive displacement. During each revolution, a fixed volume of fluid enters the casing through the suction port, filling the spaces between the gear teeth. The crescent within the pump head then separates the fluid as the idler gear turns on the pump shaft. The Internal Eccentric Gear Pump delivers smooth and accurate pumping which makes it an excellent choice for various applications.

  • Only 2 moving components within the process medium
  • Capable of pumping fluids too viscous for a Centrifugal Pump
  • Efficient suction lift applications
  • Bi-directional pumping action
  • ATEX-rating available for use in hazardous environments

How does an Internal Eccentric Gear Pump work?

Operating Principle of Yildez Eccentric Gear Pump

Image 1: Fluid entering the pump: The orange coloured section in the image represents the process medium as it is entering the pump suction port, pump casing & filling the cavities between the Idler Gear (Red) & Rotary Gear (Brown). The 3 arrows indicate the direction of fluid passage through the pump and rotational direction of the gears.

Image 2: Fluid filling the cavities & split of flow: As the fluid progresses through the pump head and fills the cavities between the gears it is also separated by the crescent shape in the pump head, which acts as a seal preventing back flow between the suction & discharge ports.

Image 3: Pump almost flooded: As the fluid fully fills the casing all cavities between the gears are completely filled in the form of locked pockets of fluid to guarantee absolute volume control and enable the pump to deliver a fixed volume per revolution.

Image 4: Pump is flooded & starts to discharge the process medium under pressure: Once the pump is fully flooded, the rotor and idler gears mesh together and form a liquid seal which is equidistant between the pump ports which then enables the fluid to exit the discharge of the pump under pressure. The delivery pressure is dependent on the installed power of the motor.
