    Construction
    5" Close coupled multi-stage submersible pumps.
    All parts in contact with the fluid both internal and external are in chrome-nickle stainless steel.
    MXSM with built-in capacitor, accessible through the delivery casing.
    Hydraulics located below the motor with the motor cooled by the pumped fluid.
    Safe operation is possible with the motor only partially submerged.
    Double shaft seal with oil chamber.
    The suction strainer prevents the entrance of solids with diameter bigger than 2 mm.
