Rotary Gear pump

It enables to feed all kinds of liquids from volatile low-viscosity liquids to high-viscosity liquids.

As it is a positive displacement pump, it is high quantitative and when feeding high-viscosity liquids, it is completely a self-priming pump, which provides less pulsation phenomenon.

As it has a simple structure, it is easy to assemble and dissemble. It is suitable for the applications required washing after use.

Principle

Dong-Hae internal rotary gear pump is designed with a simple principle under "Gear within a gear" therefore this oval type gear pump has a high efficiency and capability.

When rotating the pump shaft, the fluid enters the pump inlet and fills the gap of the idler gear and the rotor gear.

A according to rotation of the gears, the fluid is going out of the pump discharge. The fluid flows from suction to discharge as figures 1, 2 and 3 illustrate.

Feature

Versatility

- This pump can transport liquids of any viscosity,even at high and low temperatures.

At any extreme these pumps have the ability to give trouble free operation.

Good suction/inhalation capability

- Due to their original, innovative configuration these pumps are able to create a strong vacuum.

They can be used as a self vacuum pump for air and gases, and are able to provide gas mixtures without trouble.

Smooth liquid flow

- Because the gears roll in the same direction, without closing, the flow of the liquid is uninterrupted and bobble-free.

Easy maintenance and parts replacement.

- Worn parts can be easily replaced.
