What Is a Hydraulic Gear Pump?

A hydraulic gear pump is a positive displacement pump that uses rotating gears to transfer hydraulic fluid from the inlet side to the outlet side.

The basic operating process includes:

1. Hydraulic oil enters the pump chamber through the inlet port.
2. Rotating gears create a pressure difference.
3. Oil is carried between the gear teeth and pump housing.
4. Pressurized hydraulic oil exits through the outlet port.

Due to their simple structure and reliable operation, gear pumps are widely preferred in applications requiring consistent hydraulic power and cost-effective performance.
