The 2PHA*A0 Series Hydraulic Gear Pump is a compact and high-efficiency external gear pump designed for mobile and industrial hydraulic systems. Manufactured with a high-strength aluminum alloy housing, precision-machined gears, and hydrostatic pressure compensation technology, the pump delivers stable flow output, high volumetric efficiency, low noise operation, and excellent durability.

The 2PHA*A0 Series is suitable for agricultural machinery, forklifts, construction equipment, hydraulic power units, material handling systems, and various industrial hydraulic applications requiring reliable hydraulic power transmission.

Working Principle

The 2PHA*A0 Series operates on the positive displacement principle of an external gear pump.

1. Hydraulic oil enters through the suction port.
2. The drive shaft rotates the driving gear.
3. The driven gear rotates simultaneously.
4. Oil is carried around the outer circumference of the gears.
5. The meshing gears force the oil into the pressure chamber.
6. Pressurized hydraulic oil is delivered to the hydraulic system.

This design provides smooth, continuous, and reliable hydraulic power transmission.
