With a pumping capacity of up to 11,000 litres per hour, the Karcher SP 11.000 submersible pump is also suitable for use in dirty water so it's a great choice for quickly pumping water out of water butts and garden ponds. It reliably pumps out clean and dirty water containing dirt particles up to 20 mm in diameter. A prefilter is also available as an option to protect the pump impeller in case of even larger dirt particles. The SP 11.000 is fitted with a float switch that switches the pump on and off depending on the water level, thereby preventing dry running. The float switch can be fixed so that the pump can be used even at a low water level, down to a residual water depth of 25 mm. Additional extras: The robust slide ring sealing for an extra-long lifetime, a warranty which can be extended to five years and the Quick Connect connection thread for quickly connecting 1", 1 1/4" and 1 1/2" hoses.
