Principle of Rotary Distributors operation

The operating principle is simple. Water arriving by gravity or pumping passes through a fixed central column, also known as the feed column. The effluent is then admitted into a rotating body forming a loading chamber. It then flows through arms attached to the body, before escaping through distribution holes, judiciously distributed so as to act on the entire surface of the lining.

To induce the rotation of the rotary distributor, we use the energy generated by the pressure of the water column in the charging chamber. This pressure is transmitted at the distribution holes (located on the same side of the arms) and results in a driving reaction.
