Multi Stage Centrifugal Blowers



  • Inlet and outlet heads and intermediate sections are made of either cast iron or aluminium.
  • Heads and intermediate sections are clamped together by steel tie-rods.
  • Vertically connection but oriented differently.


Impeller Assembly:

  • The impellers are cast in treated aluminium alloy.
  • Fabricated by riveting.
  • Rotor assembly is then dynamically balanced.
  • Radial or curved.


Bearing Housings:

  • Independent cast iron housings.
  • Sealing of the housing is by graphitized straps, or on the larger machines by segmented carbon rings.
  • Stainless steel spring.
  • Sealing is by the use of double mechanical seals.
  • The bearings are lubricated either using grease for machines up to 5000 m3/h or by oil replenishment by a constant level oiler for the larger machines.
