4. General Information
4.1. DESCRIPTION
The LM agitator range includes the side-entry agitators with the agitator shaft fixed directly onto the motor and
the LR agitator range includes side-entry agitators with the agitator shaft fixed directly onto the gear motor. The
lantern connected to the tank has a base plate made of stainless steel. The agitator shaft is guided by a
bearing. The sealing of the shaft is carried out mechanically and is standardized according to DIN 24960.
The standard mixing element is the marine propeller type 10.
4.2. OPERATING PRINCIPLE
The LR agitators are driven by geared motors and the LM agitators are provided with direct motors.
These agitators are installed in a slanted position.
The rotation of the propeller creates a flow that impells the product to the bottom of the tank and then raises up
to the surface along the wall apposite to the agitator. The effect is promoted if the bottom is curved.
The agitator is installed decentralized to enhance the circular flow. Thus a complete homogenization of the
product is achieved.
4.3. APPLICATION
This lightweight range allows mixing and blending processes to be carried out in open and closed tanks with a
variable viscosity between 1 and 1000 cPs.
The main application is agitation of low viscosity products like wine, oil, milk, beer, alcohol, etc. in large volume
tanks.
Each agitator has performance limits. The agitator was selected for a given set of mixing conditions
when the order was placed. INOXPA shall not be held responsible for any damage that might be
suffered or malfunctioning of the equipment of the information provided by the buyer is incomplete
or incorrect (e. g. nature of the fluids or installation details).
