Magnetic Coupled Internal Eccentric Gear Pump Types

Product Features

Magnetic coupled internal eccentric gear pumps are a specialized type of gear pump used for transferring liquids and incorporating magnetic coupling technology. Instead of mechanical connections, they use magnetic fields to link the shafts, enabling secure and leak-free liquid transfer. Unlike traditional pumps, magnetic coupling pumps eliminate physical connections between the motor and pump. Instead, the magnetic field generated by the motor drives the pump shaft. This innovation provides a more reliable sealing solution than conventional mechanical systems, effectively preventing liquid leaks.

These pumps typically feature a design with internal gear mechanisms that ensure a consistent and controlled flow by drawing in and discharging liquids.

Typically, these pumps feature an internal gear mechanism that ensures a consistent and controlled flow by drawing in and discharging liquids.

Their advantages include their ability to operate without leaks, ensuring safety and reliability. They are energy-efficient, reducing power consumption while maintaining high performance and lowering operational costs. The low noise levels they produce enhance operational comfort, while their robust and sealed design simplifies maintenance, minimizing the need for frequent servicing.

These pumps are widely used in industries such as chemical processing, oil and gas, food and beverage production, electronics cooling systems, and other demanding environments. They are particularly suitable for transferring toxic, corrosive, or high-viscosity liquids, as well as in applications where leak prevention is critical.

Working Principles

 

The colored section on the side illustrates the entry of the fluid into the suction port area of the pump body, as well as into the gear cavities of the driving and driven gears. The black arrows indicate the rotation of the pump and the progression of the fluid.

As seen, the fluid transfer occurs between the gears and the enclosing pump body, rather than passing between the gears themselves.

This image represents the state of the pump just before the internal section is filled and the fluid is pushed toward the discharge port. Note how the gear cavities of the driving and driven gears create a sealed pocket for the fluid, ensuring precise volume control.

The next phase depicts the fully filled pump and the process of fluid discharge as it moves toward the outlet. Finally, the fluid is delivered to the discharge port under pressure, driven by the intermeshing gears.
