Product Details

Product Description

The QX pumps are the 5th generation of Bucher internal gear pumps, which have proven themselves in thirty vears of service around the world. Numerous improvements have been made to the straiąhtforward and robust design. Advances in the manufacturing process have made it possible without making higher demands on individual components to build pumps that are considerably lighter and more compact. A new tooth profile, conceived and optimised with the help of CAE. has vielded another significant reduction in noise levels. Large sealing areas result in higher efficiencies. The internal ring gear is supported by a hydrodynamic/ hydrostatic lubrication film, which allows operation at low viscosities or low and highlspeeds. QX pumps are therefore suitable for use with variable speed drives, where they can provide variable flow rates.

Features:

*Extremely long service life *Volumetric efficiency up to 98% *Suitable for use with variable speed drivers *Can be used with fire resistant fluids (HFB, HFC and HFD =QXV), fuels, biodegradable and low-viscosity fluids *Certifications by ATEX 2, ABS, DNV, GL, LR, NK, ... . Low flow and pressure pulsations
