Uni Track System agitator (coupling). Agitator with geared motor, double turret, spacer coupling, stirring seal, intermediate bearing (R) and flanged or direct shaft (D).
The gearmotor (1) drives the reducer’s semi-shaft (2), which is fixed by the axial clamping bolt (3). Power is transmitted through the key (4). The reducer’s semi-shaft is connected to the semi-shaft or direct shaft (5) by means of a spacer coupling (6) that allows access to the mechanical seal (7) without removing the gearmotor. The semi-shaft stopper (8) allows the entire shaft and stirrer blade assembly to remain in position while the spacer coupling is removed. In case of incorporating a shaft-semi-shaft assembly (9), these are joined thanks to the coupling of the semi-shaft (10). The different types of turbines available are attached to the shaft by different possible means (clamp, stud, welding, etc.).
The assembly rests on the upper flange of the intermediate turret (11) and the agitator is coupled to the tank through the lower flange of the turret (12). The shaft passes through this perimeter structure where, on the lower flange, it is sealed by the action of the mechanical seal.
The built-in mechanical seal is of the agitation type, balanced and single or double execution.
