The most powerful clear water submersible pump from Kärcher pumps up to 17,000 liters of clear to slightly dirty water per hour, making it perfect for pools, drainage pits, and water damage in the home. 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 17,000 Flat Level Sensor features foldable stand feet, allowing the submersible pump to start with 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 easy connection of 1", 1 1/4", and 1 1/2" hoses.
