Po Operating Principle

Its operating principle is simple. Water led in by gravity or by pumping passes through a fixed central column, called also supply column. The effluent goes, into a rotating body that forms a pressurization chamber. It then flows through the arms attached to the body and escapes through the distribution holes. These are wisely spread to water the whole media area.

To cause rotation, the energy generated by the pressure in the water column set up in the pressurization chamber
is used. This pressure is applied at the exit of distribution holes (all located on the same side of the arms) in the form of a driving reaction.


Po Options

  • Distribution arms designed in several parts
  • Beam for support and supply for hang-up type distributor
  • Revolution counter
