An individually adjustable level sensor starts the dirt water pump SP 22,000 Dirt Level Sensor immediately upon contact with water. If the water level drops below the level sensor again, the pump stops automatically after 15 seconds. This extremely powerful submersible pump is suitable for Ideal for drainage ponds, water-filled cellars or flooded ditches, for example, since it can reliably drain heavily soiled water (up to 30 mm dirt particles) at up to 22,000 l/h. In case of still more dirty water the integrated and detachable stainless steel pre-filter is used to protect against blockages. The immersion pump can also be switched to continuous operation by means of the automatic manual switch. It reliably pumps up to a residual water level of 35 millimetersin continuous operation as well as in automatic mode, with corresponding adjustment of the level sensor. The Quick Connect connecting piece can be used to connect 1", 1 1/4" and 1 1/2" hoses quickly and easily. Thanks to stainles
