Multi Stage Centrifugal Blowers

Casing:

• 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.
