The pump detects the bilge water level and starts automatically if necessary. The pump stops when the water level has dropped. The switch is implemented using semiconductor technology and has no moving parts. The Supersub allows the water level to fluctuate without starting, as it has a time delay switch (5 s). The suction nozzle has a grille that prevents larger parts from entering the impeller. The Supersub Smart 650 pump has a built-in check valve that prevents water from the outlet pipe from returning to the bilge when the pump is turned off.
40 l/min, 12 V, 19/25 mm hose outlet.
