Submersible Mixers

DESCRIPTION

Faggiolati’s mixers are projected for optimal mixing, homogenising and agitating operations in civil and industrial waste-water purification plants. The high performance ratings allow a considerable reduction in running costs. The non-clogging propeller profile, combined with an accurate projection, guarantees optimal running condictions with absolute reliability.

APPLICATIONS

Thanks to their versatility, Faggiolati’s mixers can be used in a wide range of applications. The combination of various construction materials, the stainless steel propellers and bouble silicon carbide mechanical seals allow the use of these mixers in highly corrosive conditions and at high temperatures. Typical applications for these types of mixer are: – homogenisation of heavy sludge or liquids with solid particles – Removal of sedymentary deposits. – to avoid ice formation.

CONSTRUCTIONDATA

Submersible mixers, rugged in construction, watertight electric motors accomodated in compartment, connected, by shafts of reduced lenghts, to the impellers situated by the interposition of oil chamber between the hydraulic side and the electric motor.Asynchronous, threephase electric motors, squirrel cage type, IP 68 protection, class H insulation. They are designed for S1 (continous) service, with a max overloading up to 10% environmental cooling at temperature 40oC. Starts par hour up to 15. Motors cooling comes through thermic exchange with surrounding fluid.

Ossi-Mix

The OSSI-MIX (OM) system is a new development in the sludge aeration machines sector. The constructive architecture of the machine is one of the main innovations of the new OM system and is Patent protected. The System is based on the use of a special hydraulic system with a 3-channel centrifugal impeller, which works in a special 12-outlet diffuser. The outlet of the pump is thus spread among the 12 nozzles that deliver the sludge to be aerated into 12 individual mixing chambers. In these chambers the sludge is contacted with the air supplied by a compressor, the air-sludge contact occurs in an high turbulence annular conduit. The OM system delivers twelve jets of aerated mixture, thus producing high levels of dissolved oxygen and a vigorous mixing of the sludge. The OM system achieves better performances with respect to other aeration systems, as a consequence of its integrated operations.

The OM system has been designed for a long operational life which translates in low operating costs. All parts subject to wear can be replaced easily from the edge of the tank with the use of simple tools. The impeller has an exclusive fine tuning regulation system. In summary the OM system is constitutes therefore an excellent and unrivalled technical-economical combination for the aeration of sludge, reaching unparalleled results in terms of energy efficiency and maintenance costs.

High efficiency impeller obtained from casting of stainless steel Duplex (ASTM A890 gr.4AUNS 31803)

OSSI JET

Description

The Ossi-jet system offers an excellent alternative for aeration and mixing of any civil or industrial liquid. In order to satisfy any type of requirement, it is possible to couple various pumps to various ejectors. Ossi-jet is particularly recommended for biological waste-water treatment plants, chemical waste treatment plants and fish farming.
Applications

The different type of impellers and ejectors offered by the Ossi-jet system optimise the following processes:
-oxidation;
-CO2 neutralisation;
-Ozonisation / mixing;
-Foam reduction.
AJ - Submerged Aerators

Description

AJ submerged aerators are an extremely flexible and versatile airing system for the treatment of waste-water and in every case air/water mixing is required . Elevated oxygen transfer values, low noise levels, increased reliability, low cost and rapidity of installation are just some of the advantages that our AJ submerged aerators offer.

Applications

These aerators are frequently used in waste water treatment plants, especially during homogenisation and equalisation, pre-airing stages, biological oxidation, oxidation-nitrfication, sludge stabilisation and post-airing stages. AJ radial submerged aerators can be utilised for the flotation of greases, oils and solids, at the relevant stages of flotation. This clearly means that they can be utilised during neutralization stages or in airing with high levels of oxigen. Re-circulation of the mixed air and water in the tank is carried out by two different movements: the principal or primary movement (Mp) and the induced one.

MATERIALS

The reliability and endurance of submersible electric pumps depend greatly on the characteristics of the construction materials used. For this reason, in the design of our submersible electric pumps, thanks to many years of experience in dealing with realistic difficulties, we utilise the best quality materials available on the market. These materials are manufactured by lamellar graphite grey cast iron, austenitized steel, stainless steel AISI 316, DUPLEX, HASTELLOY,SUPERDUPLEX, up to Bronze and its alloys. All the materials are rigorously controlled and certified.
Grey Cast Iron

Grey Cast IronGrey Cast Iron (called EN-GJL-250) is the principal material used for the conveyance of civil waste water, muddy waters, active sludge, rain water and white water. This material is also widely used to convey mildly aggressive or abrasive liquids with PH values > 6.5, or liquids containing sand in quantities <1 g/l.
Smelted austenitic Stainless Steel

This kind of S. S. is particularly suitable for the conveyance of acidic wastes with high chloride contents as well as brackish wastes and sea water. Thanks to its high resistance against chemical agents, it finds many applications in the Chemical Industry and in process technology.
Marine Bronze

A good and economic solution for the lifting of sea water. A zinc anode component is screwed on the pump’s diffuser. Anode increase by 2-3 times the life of the pump. For high concentrations of salty water, different materials are suggested (marine bronze, stainless steel etc.).
