PGH5-3X080RE07VE4 gear pump
Product Overview
PGH5-3X080RE07VE4 is a high-performance internal gear hydraulic pump designed for industrial hydraulic systems requiring stable pressure, low noise operation, and high efficiency. It belongs to the PGH5 Series internal gear pumps widely used in heavy industrial equipment.
This pump features a gap-compensated internal gear design that automatically adjusts clearances under pressure, ensuring excellent volumetric efficiency and long service life even under demanding operating conditions. The internal gear and pinion shaft arrangement allows hydraulic fluid to be smoothly drawn from the suction chamber and transported to the pressure chamber with minimal pulsation.
With a displacement of approximately 80 cm³/rev, the pump can operate at pressures up to 350 bar and speeds up to 3000 rpm, making it suitable for high-power hydraulic systems in manufacturing and industrial automation.
Product Features
1. Low Noise Operation
The involute internal gear tooth design provides a long meshing zone that minimizes pressure pulsation and vibration, resulting in extremely quiet operation compared with conventional external gear pumps.
2. High Pressure Capability
The PGH5 series supports working pressures up to 350 bar, enabling reliable operation in heavy-duty industrial hydraulic systems.
3. High Volumetric Efficiency
The pump uses hydraulic gap compensation technology, allowing it to maintain high efficiency across a wide range of speeds and fluid viscosities.
4. Wide Speed Range
With a speed range from 200 to 3000 rpm, the pump can adapt to various drive configurations and system requirements.
5. Long Service Life
Precision machining, heavy-duty bearings, and high-strength components ensure excellent durability and long operational life.
6. Flexible System Integration
The pump supports through-drive configurations, allowing tandem mounting with other pumps for complex hydraulic systems.

The drive shaft rotates the pinion gear, which meshes with the internal gear. As the gears rotate, hydraulic fluid is drawn into the expanding chamber at the suction side and transported to the pressure side. The crescent separator isolates the suction and discharge zones to maintain efficient flow.
