The 1PUA*B0-Y Series Hydraulic Gear Pump is a high-performance Group 1 external gear pump designed for medium-pressure hydraulic systems. Featuring a lightweight aluminum alloy housing, precision-machined alloy steel gears, and a Y-type mounting configuration, this series provides stable flow output, high volumetric efficiency, low noise operation, and long service life.

The 1PUA*B0-Y Series is widely used in agricultural machinery, construction equipment, forklifts, hydraulic power units, lifting platforms, material handling equipment, and industrial hydraulic systems requiring reliable and efficient hydraulic power transmission.

Working Principle

The 1PUA*B0-Y 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 carried around the outer circumference of the gears.
5. The meshing gears force the oil into the outlet chamber.
6. Pressurized hydraulic oil is continuously delivered to the hydraulic system.

This simple and robust design ensures efficient and reliable hydraulic power transmission.
