- 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. -
