.


  OPERATING SPECIFICATIONS

  ADVANTAGES


  Low energy consumption


  Propeller and drive units which ensure high  
  efficiency with minimum energy allow
  designing for low operating costs.



  Slow Product Processing


  Specially designed propellers allow
  designing for low-speed operation.






  HYGIENIC PROPERTIES

  ADVANTAGES


  Easy external cleaning


  Sealing Gaskets and stainless steel seat
  body design (for washing)



  Connections inside the tank
  (contamination risk is eliminated)
  are canceled as an option.

  Flange connection drive shaft inside the
  tank and special shaft connection Seat
  case and drive units


  Surface property that ensures
  easy flow


  It has flat surfaces in internal parts or there
  are no channels



  Easy Cleaning


  There are no parts that cannot be cleaned or    
  remain in the shadow between the wings.






  MAINTENANCE PROPERTIES

  ADVANTAGES

 
  All Maintenance procedures
  (Replacing shaft gasket seats, and
  other corroded parts) can be done  
  outside the tank.

  Removable Shaft and seat case drive
  units can be demounted outside the tank


  Easy and fast demounting

  Y-couplings and stainless steel parts are used.
