Internal Gear Pumps Hydraut and Hytek

Radial and axial pressure compensation

The fixed displacement internal gear pumps distributed by Hydraut combine an optimized construction geometry with axial and radial pressure compensation mechanisms.
The result is low noise levels across all operating pressures and minimized flow pulsations - decisive characteristics in systems where control precision and working environment quality are the priority.
The range includes Hydraut and Hytek brands.
