1.1 Product description
1.2 Advantages
The QX pumps are the 5th generation of Bucher internal gear pumps, which have proven themselves in thirty years
of service around the world. Numerous improvements have been made to the straightforward and robust design.
S Extremely long service life
Advances in the manufacturing process have made it poss­ ible without making higher demands on individual compo­
nents to build pumps that are considerably lighter and more compact.
S Volumetric efficiency up to 98% S Suitable for use with variable speed drivers
S Can be used with fire resistant fluids (HFB, HFC and HFD = QXV), fuels, biodegradable and low-viscosity fluids
S Certifications by ATEX 2, ABS, DNV, GL, LR, NK, ...
S Low flow and pressure pulsations
A new tooth profile, conceived and optimised with the help of CAE, has yielded 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 high speeds. QX pumps are therefore suitable for use with variable speed drives, where they can
provide variable flow rates.
1.3 ATEX compliant explosion protection The internal gear pumps QX are suitable for application in
hazardous areas and complies with the following guidelines:
