The 2.5PHA*A2 Series Hydraulic Gear Pump is a high-efficiency external gear pump engineered for medium and high-pressure hydraulic systems. Featuring a precision gear design, reinforced bearing structure, and high-strength aluminum alloy housing, this series delivers stable flow output, excellent volumetric efficiency, low noise levels, and outstanding durability under continuous operation.

The 2.5PHA*A2 Series is widely used in construction machinery, agricultural equipment, forklifts, hydraulic power units, lifting systems, machine tools, and industrial hydraulic applications requiring reliable hydraulic power transmission.

Working Principle

The 2.5PHA*A2 Series operates through two precision-machined gears rotating within a closely fitted housing.

1. Hydraulic oil enters the suction port.
2. The driving gear rotates via the input shaft.
3. The driven gear follows, creating expanding chambers that draw fluid into the pump.
4. Oil is carried around the outer circumference of the gears.
5. Fluid is forced into the outlet port under pressure and delivered to the hydraulic system.

This positive displacement design ensures continuous and reliable hydraulic flow.
