Wilo MotorsFK, HC, FKT, & T MotorsFK MotorsWet Sump Installation»»Low costs for lift station and assembly»»Low space requirement for the pumps»» Service-friendly installation and removalthanks to suspension device»»Motor is cooled by the pumped mediaFK motors feature an oil-filled motor chamber. Bymeans of an internal oil circulation cooling system,the heat produced by the motor is dissipated to thepumped media via a heat exchanger. The type FK 17.1of this series is available in explosion-proof design.Advantages:»»Continuous operation in wet and dry sumpinstallation»»Draining wet well to very low level is possible»»Cooling independent of the type of pumpedmedia»»Room ventilation not necessary in the event ofdry sump installation»»Sump volume can be reduced, resulting in lowerconstruction costsHC MotorsDry Sump Installation»»Accessible pump chamber»»»»» Pump can be monitored during operation» Quick repairs under hygienic conditions» Pump remains in operation in case of flooding» Internal cooling system, external cooling notrequiredHC motors are air filled with a closed loop water/glycol cooling system. The heat of the motor isdissipated to the pumped liquid by the coolingliquid - driven by a magnetic coupling – by meansof a highly efficient heat exchanger. This series isavailable in explosion-proof design.Advantages:»»2-chamber system – therefore control of bothmechanical shaft seals possible»»Separate leakage chamber, high processsecurity»»Cooling system hermetically sealed, nopenetration and leakage of liquid possible»»Same advantages as the FK-motorFKT MotorsFKT motors are air filled with a closed loop water/glycolor oil cooling system.
