The 2.5PLD*A0-R Series Hydraulic Gear Pump is a high-performance external gear pump with reverse rotation configuration, designed for mobile and industrial hydraulic systems requiring flexible installation and reliable hydraulic power transmission. Featuring a lightweight aluminum alloy housing, precision-machined gears, reinforced bearing support, and high-efficiency sealing technology, the A0-R series delivers stable flow output, excellent volumetric efficiency, low noise operation, and long service life.

The “R” version typically indicates a reverse rotation or special shaft configuration, making it suitable for applications where installation space or drive direction requirements differ from standard gear pumps.

Working Principle

The 2.5PLD*A0-R Series operates using two precision gears rotating inside 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 outer circumference of the gears.
5. The meshing gears force oil into the outlet port under pressure.
6. Continuous rotation provides stable hydraulic flow for the hydraulic system.

This positive displacement design ensures reliable hydraulic power generation and efficient fluid transfer.
