2 Numerous improvements havebeen made to the straightforward and robust 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 new tooth profile, conceived and optimised with the helpof CAE, has yielded another significant reduction in noiselevels. Large sealing areas result in higher Internal ring gear is supported by a hydrodynamic/hydrostatic lubrication film, which allows operation at lowviscosities or low and high speeds. QX Pumps are thereforesuitable for use with variable speed drives, where they canprovide variable flow AdvantagesSExtremely long service lifeSVolumetric efficiency up to 98%SSuitable for use with variable speed driversSCan be used with fire resistant fluids (HFB, HFC and HFD= QXV), fuels, biodegradable and low-viscosity fluidsSCertifications by ATEX 2, ABS, DNV, GL, LR, NK.
