  • Description
    The submerged aerator is designed for liquid waste
    aeration in small water treatment systems. Other fields
    of application include pond water oxygenation and fish
    farms. Thanks to its specific design, the new NOVAIR
    system guarantees optimal oxygenation of water
    treatment plants by means of a large and thick cloud
    of fine bubbles. The fluid dynamics study has been
    mainly focused on the impeller’s blade profiles, with a
    view to avoid damaging microorganisms present in the
    water when starting operation. As the aerator is installed
    vertically, its body is supplied with a supporting base.
    Technically speaking, motor cooling is guaranteed by
    large contact surfaces between motor casing and the
    liquid. The power cable is coated with resin against
    humidity and leaks and cabling has been made easier,
    in order to favour maintenance operations and cable
    replacement. The excellent wear resistance of the
    stainless steel motor shaft, with ceramic bush around
    the sealing rings, guarantees long product durability.
    Pump body, cable cover and impeller in technopolymer.
    Two-pole asynchronous submergible type motor from
    0.18 and 0.4 kW with built-in thermal protection and
    permanently connected capacitor installed in the cable
    compartment. Steel motor shaft mounted on oversized,
    greased sealed-forlife ball bearings with ceramic bush.
    Triple interposed ring seal with oil pre-chamber.
