Maintainance of water level in a rainwater storage basin at the building site.
Installation of 2 submersible pumps KTVE21.5 and KTVE22.2. The advantage here is in the integrated level control unit via electrodes. A separate floater cable does not have to be laid. The space required is determined by the diameter of the pump. In contrast to floaters, electrodes do not have to be readjusted. The level can be varied without any difficulty by mounting a screw.
