Why is it important for a chlorine feed pump to be placed lower than the chlorine tank?

It is crucial for a chlorine feed pump to be positioned lower than the chlorine tank primarily to prevent the pump from losing its prime. When a pump loses its prime, it can no longer effectively draw the chlorine solution into the pumping mechanism, leading to an interruption in the chemical feed process. Maintaining the prime ensures continuous operation and reliable dosing of chlorine into the water system, which is essential for effective disinfection.

In addition to this primary reason, a lower placement can also help to ensure gravity assists in the flow of chlorine solution to the pump, further reducing the risk of cavitation or air pockets that might disrupt the delivery of the chlorine. Proper positioning is a key factor in ensuring efficient and effective water treatment processes.
