The 0PUA*B1 Series Hydraulic Gear Pump is a compact, lightweight, and high-efficiency external gear pump designed for miniature hydraulic power units and low-to-medium flow hydraulic systems. Featuring a precision-machined gear set, high-strength aluminum alloy housing, and optimized bearing support structure, the pump delivers stable flow output, excellent volumetric efficiency, low noise operation, and long service life.

The 0PUA*B1 Series is particularly suitable for compact hydraulic equipment where installation space is limited but reliable hydraulic performance is required. Similar micro-displacement gear pumps are commonly used in small hydraulic power packs, lifting equipment, agricultural machinery, and industrial automation systems.

Working Principle

The 0PUA*B1 Series operates on 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 outside of the gear teeth.
5. The meshing gears force oil into the outlet chamber.
6. Pressurized hydraulic oil is continuously supplied to the hydraulic system.

This design ensures smooth and reliable hydraulic power transmission with minimal flow pulsation. Similar miniature gear pump designs provide high efficiency and compact dimensions for small hydraulic systems.
