External gear pump is an integral part of the oil-injected radial piston pump. It is a common type of hydrostatic transmission pump which is commonly used in machine tools, power plant, plastics and other equipment.

External gear pumps are used to transfer and pump liquid that is relatively viscous and abrasive, such as oil, gasoline, diesel fuel, or most other kinds of hydrocarbon liquids. They are also used for pumping a variety of other liquids such as water, paint, and glycol.

The pump operates on the principle of meshing external gears, with the inner and outer gear sets turning in opposite directions, providing a positive displacement. The two gear sets are mounted in two parallel diaphragms, one on each side of the pump, which form sealed chambers when the pump is in operation. The gear pumps provide a steady flow of fluid at relatively low pressure, up to a maximum pressure of 200 psi.

External gear pumps are usually used in hydraulic systems to provide a steady flow of hydraulic fluid, but they can also be used in other applications such as cooling systems, oil circulation systems, and cooling systems. In addition, some industries use them for lubrication and oil circulation.

External gear pump is a common type of pump used in many industries, it is mainly used for circulating liquids such as oil, fuel, water and many more. It is an ideal choice for high-pressure applications due to its efficient and economical operation.
