Common Questions

A hydraulic external gear pump uses rotating gears or gears to transport fluid. The rotating gears form a liquid seal with the pump casing and create a vacuum at the pump inlet. The fluid sucked into the pump is enclosed in the cavity of the rotating gear and transferred to the discharge port.

The working cycle of a hydraulic gear pump is divided into three stages: fluid filling, transmission operation, and fluid discharge.

These hydraulic gear pumps work under heavy load operating conditions and transfer high hydraulic power, with good hydraulic, mechanical, and volumetric efficiency, low noise levels, and are an ideal choice for industrial transmission and mobile industrial fields.

The basic components of the hydraulic pump include a gear set supported by two aluminum liners, a main body, a fixed flange, and a cover.
