The most powerful clear water submersible pump from Kärcher can drain up to 14,000 liters of clear to slightly dirty water per hour, making it perfect for pools, drainage pits, and water damage in homes and basements. For heavier contamination and to protect the pump impeller, the use of the included stainless steel pre-filter is recommended. The robust stainless steel housing and the mechanical seal make the pump particularly durable. The flat suction submersible pump is equipped with a continuously adjustable level sensor that starts the pump immediately upon contact with water. Additionally, the SP 6 Flat Inox features foldable stand feet, allowing the pump to start at a water level of just 7 millimeters. With the switch, the pump can be set to continuous operation in manual mode. Whether in continuous operation or automatic mode, it pumps down to a residual water height of 1 millimeter, depending on how the level sensor is set. Furthermore, the Quick Connect connection socket allows for particularly fast and uncomplicated connection of 1", 1 1/4", and 1 1/2" hoses. EU version.
