The 2PHA*B2 Series Hydraulic Gear Pump is a high-performance external gear pump designed for medium and high-pressure hydraulic systems. Manufactured with precision-machined gears, high-strength aluminum alloy housing, and advanced bearing support technology, the B2 series offers excellent volumetric efficiency, stable flow output, low noise operation, and long service life.

The 2PHA*B2 Series is widely used in agricultural machinery, construction equipment, forklifts, hydraulic power units, lifting machinery, machine tools, and various industrial and mobile hydraulic systems requiring reliable hydraulic power transmission.

Working Principle

The 2PHA*B2 Series operates through two precision gears rotating inside a close-tolerance housing.

1. Hydraulic oil enters through the suction port.
2. The drive gear is rotated by the input shaft.
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 oil is delivered to the hydraulic system.

This positive displacement principle ensures continuous and stable hydraulic power generation.
