QXEH Internal Gear Pumps

Highly dynamic variable-speed pump operation

The QXEH series has been specially developed for pumping duties in highly dynamic servo drives with a reversing function. Using the pinion-shaft technology, high pressures up to 280 bar are developed in a single stage. QXEH pumps are therefore particularly well suited for a wide range of applications in industrial hydraulics where there are high demands on power density, energy efficiency and machine productivity. At the same time, they ensure maximum operational reliability coupled with minimal flow- and pressure-pulsations even during operation with highly dynamic load cycles.

QXEH Internal Gear Pumps
