Never again will you have flooded basement spaces. You can set up the pump in your basement when water enters due to flooding or groundwater infiltration and reaches a height of 30 mm. The pump automatically switches on. It drains the water down to 1 mm from your basement and then turns off via the integrated electronic control. The integrated non-return valve in the discharge connection prevents water from flowing back down the riser pipe. The sensor switch can be fixed in 3 positions as well as in a continuous operation mode, with the lowest activation point set at 30 mm. It is ideal for draining flat surfaces and can also be used as a standard clear water pump for transferring water from containers or cisterns.
