In external gear pumps, the two gears rotate in opposite directions, and fluid is transferred between the teeth of the gears. This type of gear pump is commonly used for high-pressure applications due to its simplicity, efficiency, and ease of maintenance. External gear pumps are typically used in industries such as construction, agriculture, and manufacturing, where high pressures and continuous fluid flow are essential.

Internal gear pumps feature one gear inside the other, with the smaller gear rotating inside the larger gear. The fluid is transferred between the outer and inner gear teeth, which allows for higher pressure levels and quieter operation compared to external gear pumps. These pumps are often used in applications where reduced noise levels and smoother operation are required, such as in the automotive and food processing industries.

High-pressure gear pumps are known for their ability to efficiently transfer hydraulic fluid under high pressure. Their design allows for a consistent and reliable flow of fluid, even in demanding applications. The positive displacement nature of the pump ensures that the same volume of fluid is delivered with each rotation, providing precision and reliability in systems that require high pressure and consistent flow.

High-pressure gear pumps are relatively compact and rugged, making them suitable for use in environments where space is limited. Their durability ensures they can withstand the harsh conditions often found in industrial settings, such as exposure to high temperatures, pressure, and contaminants. This makes them a preferred choice in heavy-duty machinery and systems that require reliable performance over long periods.

These pumps are highly versatile and can be used in a wide range of industries, including construction, mining, automotive, and agriculture. High-pressure gear pumps are commonly found in hydraulic systems that power cranes, excavators, trucks, and various other machinery. They are also used in lubrication systems, where high-pressure oil is required to maintain the proper operation of engines, gears, and other mechanical components.
