• CD-6 Impeller

    The ChemineerTM Concave Disc (CD-6) impeller is revolutionizing the field of agitated gas dispersion. Given the same conditions of power per volume and superficial gas velocity, mass transfer factors can nearly double when the CD-6 impeller is used instead of the conventional flat blade disc impeller.



    In applications of high energy agitation and high gas rates, this impeller significantly improves the mass transfer factor, kLa. Our Concave Disc (CD-6) impeller improves the mass transfer rate as much as 50% in gas dispersion operations.


    • Curved blade design similar to the BT-6
    • Gas dispersing capability over two times that of the D-6 (Rushton) turbine


    • Available in normal configuration of six blades with a choice of welded, bolted or adjustable blades
    • Carbon steel or 316 stainless steel
    • Fabrications from special alloys are available
    • Sizes ranging from 18 to 72 inches in diameter
