Aluminum gear pumps are mechanical devices used to transfer fluids, such as oil or fuel, in various industrial applications. They operate by using two interlocking gears within a tight-fitting housing to create suction and discharge pressures, facilitating the movement of the fluid from one location to another. These pumps are constructed primarily from aluminum, a lightweight and durable material, making them suitable for a wide range of environments and conditions. They are prized for their reliability, efficiency, and ability to handle viscous fluids effectively.
