Process Gas Blowers series GQ

Positive Displacement Blowers

Blower power for special applications.

GQ process gas blowers are ideal for use in steel plants for the compression of process, cooling, and seal gas. These blowers are often used as 2-stage units and are up to the most extreme challenges.

FIELDS OF APPLICATION:

  1. Especially used in direct reduction plants for conveying of process- and cooling gas. Operating pressure range up to max. pe=2,5 bar where the medium has the corresponding inlet pressure. Max. pressure difference 1100 mbar.
  2. Especially used in direct reduction plants for conveying of process- and cooling gas. Operating pressure range up to max. pe=6 bar where the medium has the corresponding inlet pressure. Max. pressure difference 1500 mbar.

DESIGN:

  1. Housing compression-proof for PN 2,5. Cylinder with noise reducing chamber on the discharge side, housing with connections for water injection - and water flushing, as well as for lubrication - and purge oil supply systems.
  2. Housing compression-proof for PN 6 (only GQ 20f20 and GQ 21.21). Cylinder with noise reducing chamber on the discharge side, housing with connections for water injection - and water flushing, as well as for lubrication - and purge oil supply systems.

SHAFT SEALINGS:

  • Conveying chamber by single-acting oil-purged mechanical seals in combination with labyrinth seals.
  • Drive shaft is sealed by 3 radial seal rings.

DIRECTION OF FLOW:

Horizontal, selective to the left or to the right

DRIVE: 

Either via flexibly coupled spur gear or direct coupling with drive motor. Via flexibly coupled spur gear.
