Fed system for GRANUDOS-Plus

For multiple pool complexes

Feed system for the distribution of the pH-neutral chlorine solution that is produced by the GRANUDOS-Plus to the different pool cycles by dosing lines. The dosing of the chlorine solution to the pools is controlled by external controllers.

A solenoid centrifugal pump with PVDF head is generating a constant pre-pressure for the dosing lines for the single pools through a pressure retention valve. If a control valve of a dosing line is opened the same flow rate is always realised, no matter how many dosing lines are actuated.
