This submersible pump has a power of 250W and thus pumps clean water from the cellar, swimming pool, pond, etc. at a flow rate of 5500 liters per hour. The submersible pump can pump out the water up to 5mm. The POWXG9504 works with an external float where the pump switches on automatically when there is too much water in the room. The pump will also switch off automatically once the desired water level has been reached. You determine the switch-on and switch-off level of the pump yourself.
