The white dosing hose in the dosing device must be replaced preventively every year. In the event of hose breakage, the chemicals flow into the dosing pump with the risk of irreparable damage to the dosing pump.
In general there are 5 mechanisms through which the dosing hose can break:
A. The dosing hose is at the end of its life (with chemical compatibility) after 500/600 performance hours
B. Dosage of incompatible products with the "Santoprene" material of the dosing tube (PH regulation with HCI)
C. Increase of chemicals. Bottle with cling and acid on the pumps / pumps mounted on the vertical bus.
D. The check valve of the pump or the injection can be blocked by limestone (more often in calcareous waters. These must be regularly decanted, by dismantling the tubes and placing them in a descaling liquid (HCl, Vinegar, descaler coffee maker)
E. Empty dosing vessel, as a result of which the peristaltic pump keeps running and the 500/600 hours of running time can be reached very quickly
