BF – portable sludge pumps

The BF series portable submersible pumps are special pumps designed for pumping wastewater polluted with mechanical impurities of mainly non-abrasive character, as e.g. mud, ash, wooden pieces, sewage etc. and in smaller extent also of abrasive character, as e.g. sand, sandy grit etc. When using for pumping wastewater containing substances of abrasive character, it is necessary to expect an increased wear and tear of the hydraulic part, gufero sealing, shaft and the sealing. The maximum temperature of the pumped liquid is 35°C. The maximum density of the pumped liquid is 1,100 kg/m3. The maximum immersion depth of the pumps is 10 m at liquid density of 1,000 kg/m3. The real immersion depth is always at least by 1 m shorter than the supply cable length. The pumps are widely used particularly in building industry, excavation and amelioration works, in removing flood consequences as drainage of flooded cellars, basements, septic tanks and wastewater reservoirs etc. The allowed pH of the pumped liquid ranges from 6 to 9.
