The 2PHA*A0-R Series Hydraulic Gear Pump is a compact and high-efficiency external gear pump designed for hydraulic systems requiring reverse rotation (R type) or special installation configurations. Manufactured with a high-strength aluminum alloy housing, precision-machined gears, and advanced sealing technology, this series provides stable flow delivery, excellent pressure performance, low noise operation, and long service life.

The 2PHA*A0-R Series is widely used in agricultural machinery, construction equipment, forklifts, hydraulic power units, lifting systems, road machinery, and industrial hydraulic applications where reliable hydraulic power transmission is essential.

Working Principle

The 2PHA*A0-R Series operates through two precision gears rotating within a closely fitted housing.

1. Hydraulic oil enters through the inlet port.
2. The drive shaft rotates the driving gear.
3. The driven gear rotates simultaneously.
4. Oil is carried around the gear periphery.
5. The meshing gears force oil into the outlet port under pressure.
6. Continuous rotation generates stable hydraulic flow for the hydraulic system.

This positive displacement mechanism ensures reliable and efficient hydraulic power transmission.
