LR/LM Bottom Side Entry Agitator

LR/LM Bottom Side Entry Agitator Application

The bottom side entry agitators are used in process and storage  tanks in the applications of the food-processing industry. The main application is agitation of low viscosity products like wine, oil, milk, beer, alcohol, etc. in large volume tanks.

Bottom Side Entry Agitator – LR/LM 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 opposite to the agitator. The effect is promoted if the bottom is rounded.

The agitator is installed decentralized to enhance the circular flow. Thus,
