The 1PUA*Q1 Series Hydraulic Gear Pump is a high-performance Group 1 external gear pump engineered for medium-pressure hydraulic systems. Designed with a high-strength aluminum alloy housing, precision-machined gears, and advanced pressure-balancing technology, this series provides stable flow output, high efficiency, low noise operation, and excellent reliability.

The 1PUA*Q1 Series is widely used in agricultural machinery, construction equipment, forklifts, hydraulic power units, material handling systems, lifting equipment, and industrial hydraulic applications requiring dependable hydraulic power transmission.

Working Principle

The 1PUA*Q1 Series operates according to 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 force the oil into the outlet chamber.
6. Pressurized hydraulic oil is continuously delivered to the hydraulic system.

This simple and efficient design ensures stable hydraulic power transmission with minimal maintenance requirements.
