Pumps for Special ApplicationsPropeller pumps with submersible motor for use in pipe sumpsSeries description Wilo-EMU KPR…MotorMotor housing made of grey cast iron.The air-filled T-motors give off their heat to the surrounding fluid.The units can only be operated directly in the pipeline in wet sumpinstallation due to their design.The cable inlet is sealed longitudinally watertight. The cable lengthcan be individually configured.SealingThe sealing of the motor space from the fluid is done in various ways.There are different variants, depending on the type of motor:Wilo-EMU KPR…Propeller pump with submersible motor for use in pipe sumpsType key for hydraulicsExample: Wilo-EMU KPR 760-16°KPR = Axial pump760 = Propeller diameter16° = Angle setting of the propeller blade• Two mechanical seals (G)• Block seal cartridge (K)Options• Special materials and coatings against corrosion and abrasion• Diverse monitoring equipment depending on the type of motor (sealingchamber control, bimetal or PTC thermistor temperature sensor,bearing temperature, ...)• Switchgears• Level controlsType key for motorsExample: Wilo-EMU T49-10/70P ExT = Motor version49 = Size8 = Number of poles70 = Package lengthP = Motor for propeller pumpEx = Ex approvalFields of applicationPumping of mechanically pre-cleaned sewage and activated sludgein water treatment systems.Further fields of application are in flood protection, as well as industrialand cooling water supplies in the industrial and commercialareas.ConstructionSubmersible sewage pump as submersible monobloc unit for wetsump installation.HydraulicsHousing and impeller made of grey cast iron.
