Uni Track System agitator (coupling). Agitador with geared motor, double turret, spacer coupling, mixer mechanical seal and flanged or direct shaft (D).
The gearmotor (1) drives the gearbox semi-shaft (2), which is fixed by the axial clamping bolt (3). Power is transmitted through the key (4). The gearbox semi-shaft is connected to the semi-shaft or direct shaft (5) by methods of a spacer coupling (6) that allows access to the mechanical seal (7) without removing the gearmotor. The semi-shaft stopper (8) permits the entire shaft and mixing 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 by the semi-shaft coupling (10). The diferent types of turbines available are assembled to the shaft by diferent possible methods (clamp, set screw, 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 perimetral structure where, on the lower flange, it is sealed by the action of the mechanical seal. The fastening of the shaft is done by a bearing incorporated in the mechanical seal.
The mechanical seal is of agitation type, balanced and of single or double execution.
