TECHNICAL CHARACTERISTICS

SUPPORTED SHAFT

Direct drive mixers, with rigid coupling and guide bushings adjacent to the impeller. The steel shaft is coated with plastic (PP, PVC, PVDF) for complete protection against corrosion.

CUSTOM-MADE LENGTHS

Lengths from 250 to 3000 mm depending on the depth of the tanks. In lengths of over 2000 mm, AG mixers are structurally reinforced with anti-vibration fibreglass shells.

High-speed industrial mixers for water treatment, solids suspension, powder dissolution

FAST ROTATION

High-speed mixers for low viscosity and slightly charged corrosive fluids. Typically used in the purification and neutralisation of water, and in preparing solutions from granules, powder or liquid.

THREE-BLADE IMPELLER

3-blade marine propeller made of thermoplastic (PP,PVC, PVDF), with axial or semi-axial flow. With no metal inserts and insensitive to the direction of rotation.

MULTIPLE FIELDS OF APPLICATION

Traditionally used in civil and industrial purification processes, in the chemical and pharmaceutical industries, AG top-entry mixers can actually be used in a wide range of applications. Savino Barbera industrial mixers are ideal for keeping the chemical-physical characteristics of many industrial fluids uniform. They are particularly suitable for liquid-solid mixing and mixing liquids with solids in suspension.

CONSTRUCTION MATERIALS

Three-blade marine propeller in PP for acid waters and corrosive fluids

PP

The most widely used
anti-acid plastic polymer for use in corrosive environments. It offers good resistance to most acid and alkaline solutions and can be used, depending on the concentration of the aggressive liquids, up to a temperature of 80°C.

Three-blade marine propeller in PVC for chemicals and aggressive solutions

PVC

Plastic material with excellent resistance to acids, bases, saline solutions and organic compounds. PVC is generally used when treating sodium hypochlorite (NaClO).
At low temperatures it becomes fragile. The operating temperature is between 40 and 60°C.

PVDF

Thermoplastic with exceptional resistance to corrosion and temperature. PVDF covers a wide range of uses but is ideal for highly concentrated acids.It is not suitable for certain inorganic bases, such as caustic soda. Operating temperature: max. 100°C

EXAMPLES OF APPLICATIONS

Acidification and neutralisation of water
Fertigation systems
Dissolution of salts in liquids
Denitrification processes
Preparation of polyelectrolyte solutions
Chlorination systems

OPTIONS THAT MAKE A DIFFERENCE

Industrial agitators with standard baseplates or tailor-made supports

CUSTOM-MADE FLANGE

Le piastre di appoggio in PVC normalmente vengono prodotte in misure standard, conformi a dimensioni e pesi dei vari modelli dei nostri agitatori industriali. Le flange sono però disponibili anche in forme e dimensioni realizzate su disegno, per adattarsi alle specifiche di vasche e serbatoi dalle forme meno comuni.

Tanks and portable metal frames for Savino Barbera industral mixers

FRAMES AND TANKS

AG top entering mixers can be mounted inside tanks of varying capacity, turning them into mixing units or production stations. These mixing stations can be equipped with various optional features, including: metal frames, (fixed version) metal frames with wheels (mobile version), electrical panels, drainage valves, containment tanks.

GUIDE BUSHINGS

AG mixer shafts are inserted inside a support column and are supported by a pair of bushings near the end of the mixer. The guide bushings are available in materials suited to aggressive and also charged liquids: filled-PTFE, sintered ceramic or silicon carbide (SiC).

HOW TO CHOOSE A MIXER

In order to size a specific mixer and ensure effective mixing, it is necessary to evaluate several variables which often interact with each other: the type of liquid (or liquids) to be mixed, the volume to be handled, the purpose of the process, the geometry of the container, the position of the mixer. In this preliminary operation, the manufacturer’s experience is always a decisive added value, given the changing conditions that frequently affect industrial processes and liquids.
