Internal Gear Pumps QXEHX – for speed up to 4600 rpm

Description

The newly developed QXEHX pump series is the successor to the QXEH and offers several new advantages. 

In addition to the proven reliability and very low noise level of all Bucher Hydraulics internal gear units, the new QXEHX series has been specially developed for very high speeds. The hydrodynamic lubrication has been improved still more, increasing the operational reliability of the pump many times over. Overlapping displacements now offer a greater choice, so you can always find the optimum pump size for every application.

Advantages

  • Maximum reliability, even in reversing operation
  • Very low noise levels
  • Cavitation-resistant with critical fluids
  • Ideally suited for use with variable-speed drives
  • Very long service life even with cyclic loading
  • Heavy-duty materials; can thus be used in difficult environments and with various fluid
