Max-Flo Power Pump generates continuous and reliable water circulation for a wide variety of pond applications, including pressurized filters, surface skimmers, filter falls and other filtration systems. It is also ideal for use in pond less waterfalls and for creating waterfalls and watercourses. The Max-Flo Power Pump features an integrated electronic float control system that electronically turns the pump off before running dry, and a self-closing thermal switch that will shut the pump off when over heated, protecting it from potential damage caused by overheating. The pump will automatically reset itself and restart after tripping the thermal switch.
