The Kärcher SP 3 submersible dirty water pump is invaluable for tackling floods, cleaning your pond and other jobs involving moving dirty or clean water. Capable of pumping 7,000 litres of water an hour, it can be used with a standard garden hose by using a tap adapter to connect it. This pump has a dirty water filter capable of handling dirt particles of up to 20mm in diameter. A float switch turns the pump on and off automatically, preventing it from dry running and ensuring it swiftly gets to work if an area starts to flood. To clear the last remaining water, simply fix the float switch in place above the pump and monitor its progress. A ceramic motor seal protects the motor and pump to prolong the life of this machine, and it comes with a G1 thread connector.
