The Kärcher SP 5 Dual submersible dirty water pump has a 2-in-1 function that means it can be used for both clean and dirty water. It gets the job done fast, pumping 9,500 litres of water an hour from flooded cellars, garden ponds and pools. This machine's dirty water filter is capable of handling dirt particles of up to 20mm in diameter. A height-adjustable float switch turns the pump on and off automatically when the water is at your desired level and prevents dry running, and there's also a flat pick-up setting of 1mm to get the last of the water up. Connect this pump to a hose quickly and easily using the Quick Connect system. To prolong the life of the machine, it has a ceramic motor seal to protect the motor and pump.
