C2-Sewage Pumps DN 32 to DN 600 - 2008.pdf

Pumps for Special ApplicationsSubmersible motor pumps with maceratorSeries description Wilo-EMU FA…MMotorMotor housing made of grey cast iron.The air-filled T-motors give off their heat to the surrounding fluidand can therefore only be operated continuously outside of the fluidin an exceptional case. The operating mode is documented here specificto type.The cable inlet is sealed longitudinally watertight. Cable lengths areavailable at fixed stages starting from 5 m.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 FA…MSewage pump with submersible motor and maceratorType key for hydraulicsExample: Wilo-EMU FA 03.13MFA = Submersible sewage pump03 = Nominal width of the pressure port DN 3613 = Performance characteristic numberM = MaceratorType key for motorsExample: Wilo-EMU T12-2/11G Ex• On the fluid side with a mechanical seal, on motor side with a radialshaft sealing ring (version H)• Two mechanical seals (G)• Block seal cartridge (K)Options• Coatings against corrosion• Diverse monitoring equipment depending on the type of motor (sealingchamber control, bimetal or PTC thermistor temperature sensor,bearing temperature, ...)• Plugs and switchgear• Level controlsT = Motor version12 = Size2 = Number of poles11 = Package lengthG = Sealing versionEx = Ex approvalFields of applicationSewage pump with macerator for pressurised drainage with longsmall-dimensioned pressure pipes.
