Pitched Blade Turbines


  • Pitched blade turbines are axial flow impellers used in top-entering agitators.
  • A pitched blade turbine consists of a hub on which an even number of blades are mounted at an angle of 10 to 90 degree with respect to the horizontal.
  • The most commonly used impeller of this type is the four-bladed 45 degree pitched-blade turbine.
  • The pitched-blade turbine is generally used for impeller diameters ranging from 450 mm to 3 m with connected power of up to 500 hp. It is used primarily in flow control applications. Figure  shows the commonly used 45 degree pitched-blade turbine.
  • Since the fluid discharge from a pitched-blade turbine has both axial and radial components, it is considered a mixed-flow impeller.
  • The pitched-blade turbine impeller is generally fabricated. The blades may be welded directly onto the impeller shaft or are bolted to the shaft hub.
  • The pitched blade turbine is available in up-pumping and down-pump configration depending on the application
