  • Mixed flow pump

    A mixed flow pump is a centrifugal pump with a mixed flow impeller.The specific speeds (n s) lie between 35 and 80 rpmfor low-speed mixed flow pumps, and between 80 and 160 rpm for higher-speed mixed flow pumps (in special cases even higher).Mixed flow pumps cover the transition range between radial flow pumps and axial flow pumps (e. g. propeller pumps).
