How to choose correct Overhead Stirrer ?


Choosing the right stirring paddle can make your overhead stirrer show excellent stirring effect. When choosing a stirring paddle, you need to consider: the flow direction of the medium that the stirring paddle can cause during stirring; the application range of the stirring paddle mainly depends on the speed range and the maximum torque it can achieve.

If you need gas handling in liquids <500 mPas, you can choose a radial flow impeller.

If you need homogenization or suspension handling <500 mPas, you can choose a propeller or blade impeller

If you need to handle medium viscosity samples >500 mPas, you can choose an anchor impeller or a fan impeller,


So where should the stirring paddle be placed in the container?

The stirring paddle shaft is in the center of the container

The distance between the stirring paddle and the bottom (h/d) = 0.3

(h: distance between the paddle and the bottom; d: diameter of the stirring paddle)

Only when the position is correct can a good stirring effect be achieved.
