The 1PLA*A2 Series Hydraulic Gear Pump is a high-performance Group 1 external gear pump designed for medium-pressure hydraulic systems. Built with a high-strength aluminum alloy housing, precision-machined alloy steel gears, and an optimized internal pressure-balancing structure, this series provides excellent volumetric efficiency, stable flow output, low noise operation, and long service life.

The 1PLA*A2 Series is widely used in agricultural machinery, construction equipment, forklifts, hydraulic power units, lifting platforms, material handling systems, industrial automation equipment, and mobile hydraulic machinery requiring reliable hydraulic power transmission.

Working Principle

The 1PLA*A2 Series operates according to the positive displacement principle of external gear pumps.

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 transported around the outer circumference of the gears.
5. The meshing gears force the oil into the pressure chamber.
6. Pressurized hydraulic oil is continuously delivered to the hydraulic system.

This design ensures efficient hydraulic power transmission with reliable and stable performance.
