    Construction
    5" Close coupled multi-stage submersible pumps. Easy to install, compact
    and plug and play with integrated pressure transducer for automatic control of
    starting/stopping of the pump when utilization points are opened/closed with
    E-MPSM 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.
