BS 2201.011

Summary

Product identification

The Flygt 2201.011 is a submersible dewatering pump designed for tough operating conditions. It is suitable for applications where water or liquid contains high amounts of clay, stone chips, drilling fines, or heavy sediment. These portable and robust aluminum pumps are used for dewatering construction sites, draining flooded areas, and handling water in mines or on oil platforms. The pump can handle water containing relatively abrasive solids.
