MD/MDN Vertical Agitator

The MD and MDN series vertical agitators represent InoxMIM's high-performance entry-level range within its agitation catalog. They have been developed from the ground up in fluid engineering to offer a robust, reliable, and economically efficient solution for the preparation of chemical reagents and simple mixtures in small and medium-volume tanks.

The operating principle of these units is based on the high rotational speed of their impeller. Lacking a gearmotor, the shaft rotates at the nominal motor speed (typically 750, 1,000, 1,500 rpm depending on the motor poles). This high kinetic energy is transmitted to the fluid through the MARINE type propeller, which generates a purely axial flow pattern. This hydrodynamic profile forcefully pushes the liquid to the bottom of the tank, where it impacts and rises along the tank walls, creating global recirculation that eliminates dead zones and prevents the sedimentation of heavy particles.

At a mechanical structural level, one of the greatest engineering successes of this series is the connection system between the motor and the shaft. Instead of using solid shafts that increase product cost and complicate replacement, InoxMIM uses a precision rigid coupling sleeve. This element not only safely transmits torque but also greatly simplifies routine maintenance tasks.

If the motor breaks down, the plant operator can separate it from the agitator shaft in a matter of minutes, replace it with a standard IEC motor from the market, and resume production, reducing downtime to an absolute minimum. Furthermore, the modular design ensures the interchangeability of agitation components, providing the plant with great versatility if mixing conditions change in the future.
