The 1PUA*Q2 Series Hydraulic Gear Pump is a high-performance Group 1 external gear pump designed for medium-pressure hydraulic applications. Featuring a robust aluminum alloy housing, precision-machined alloy steel gears, and a Q2 mounting configuration, this series offers excellent volumetric efficiency, stable flow output, low noise operation, and long-term reliability.

The 1PUA*Q2 Series is widely used in agricultural machinery, construction equipment, forklifts, hydraulic power units, material handling systems, lifting equipment, and various industrial hydraulic applications where dependable hydraulic power transmission is essential.

Working Principle

The 1PUA*Q2 Series operates on the positive displacement principle of external gear pumps.

1. Hydraulic oil enters 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 create pressure and force oil into the outlet chamber.
6. Pressurized hydraulic oil is continuously supplied to the hydraulic system.

This simple and efficient design ensures stable hydraulic power transmission and reliable operation.
