TECHNICAL CHARACTERISTICS
GEAR-DRIVE MIXERS
AR Series agitators are equipped with gear reducers (usually angular gearmotors with a monolithic cast iron casing lubricated-for-life). Coaxial gearmotors can also be fitted by request. Motor rotation speed: from 55 to 110 rpm. Possibility of use with inverter (60 Hz max).
HIGH-EFFICIENCY IMPELLERS
The profile of three-blade and four-blade impellers allows the use of low-power motors. The impellers are ideal for fluids that cannot be subjected to high turbulence or for mixtures where the pumping action must prevail over the shear. Dual impellers by request (in the metal version only).
SLOW-SPEED MIXERS
Top mounted geared mixers used typically when gentle mixing of the liquid is required, as in the case of water flocculation where the impeller blades must not affect the suspended flakes. Characterised by clockwise rotation when looking from the motor side: the flow generated is always downward.
MADE OF PLASTIC AND METAL
Flange mounted mixers with cantilever shaft connected to the gearmotor with a rigid coupling. Custom-made construction lengths from 250 to 3500 mm depending on the depth of the tank. Available in corrosion-resistant plastic materials and stainless steel.

CONSTRUCTION MATERIALS
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.
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
AISI 304
AR mixers are also available in stainless steel. This version can be used to mix industrial liquids that are not particularly aggressive, such as: fertilisers, manures, quenching treatments, wastewater, graphite suspensions, mineral oils. Maximum operating temperature: approx. 100°C
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.
