    Submersible electric pumps particularly suitable for the
    removal of drainage water in construction sites, open
    mines or quarries. Thanks to their rugged construction

    AISI 304 stainless steel, double mechanical seal in
    silicon carbide/silicon carbide on pump side and carbon/
    alumina on motor side. Suction screen in AISI 304
    stainless steel. Pump body in EN GJL 200 cast iron clad
    internally with abrasion and wear resistant Nitrile rubber
    (NR). Dry-type asynchronous sealed motor, cooled by
