The 2.5PHA*A1 Series Hydraulic Gear Pump is a high-performance external gear pump designed for medium-pressure hydraulic systems. Manufactured with precision-machined gears, high-strength aluminum housing, and advanced sealing technology, this series offers stable performance, high volumetric efficiency, low noise operation, and long service life.

The 2.5PHA*A1 Series is widely used in agricultural machinery, construction equipment, industrial hydraulic power units, lifting machinery, material handling systems, machine tools, and mobile hydraulic applications.

Working Principle

The 2.5PHA*A1 Series gear pump operates by meshing two precision gears inside the pump housing.

1. The drive shaft rotates the driving gear.
2. The driven gear rotates simultaneously.
3. Oil is drawn into the suction chamber.
4. Hydraulic fluid is transported around the gear periphery.
5. The fluid is forced out through the outlet port under pressure.

This positive displacement design provides a stable and continuous flow of hydraulic oil for system operation.
