What is an External Gear Pump?

An External Gear Pump is a type of positive displacement pump that employs two meshing gears located outside a compact housing to move fluids. The meshing action of the gears creates a continuous flow as fluid is trapped and displaced between the gear teeth and the casing.

How Does an External Gear Pump Work?

The pump operates by the rotation of the gears, which capture a fixed volume of fluid in the spaces between the gear teeth and the pump housing. As the gears rotate in opposite directions, this fluid is forced from the pump’s inlet to its outlet, providing a smooth, pulse-free flow.

What Fluids are Commonly Handled by External Gear Pumps?

External Gear Pumps are ideal for handling moderately viscous to highly viscous fluids such as oils, lubricants, paints, and certain food products. However, they are typically not recommended for pumping abrasive or particulate-laden fluids.

An External Gear Pump is a type of positive displacement pump widely used for fluid transfer and hydraulic applications. It consists of two meshing gears that rotate within a housing. As the gears rotate, they create suction at the pump inlet, drawing fluid into the spaces between the gear teeth and the pump casing. The fluid is then transported around the periphery of the gears to the outlet side, where it is discharged. This design allows for a smooth and consistent flow of liquid, making external gear pumps ideal for handling viscous fluids such as oils, chemicals, and certain types of fuel.
