Equipped with a level sensor and integrated prefilter, the SP 22. 000 Sensor can pump out dirty water at a rate of up to 22,000 litres per hour. An individually adjustable level sensor starts the SP 22.000 Sensor immediately upon contact with water. If the water level drops below the level sensor again, the pump stops automatically after 15 seconds. The extremely powerful submersible pump is ideal for draining, for example, large garden ponds, flooded basements or construction pits, as it can reliably pump out dirty water (dirt particles of up to 30 mm) at a rate of up to 22,000 litres per hour.
