Hydrosmart
L932 plus
HydroSmart pump controllers are the new generation of fully electronic boards to protect and operate your water pumps.
It is a practical, simple, compact and highly automated solution for the management of differential pressure systems, sewage systems, rainwater, wastewater ejectors and elevation, transfer or impulsion of water for one or two pumps, replacing the traditional panels that are manufactured by basic protections in metal boxes.
