Two people on stage

Process Gas Blowers series GR

Positive Displacement Blowers

Blower power for special applications.

The 1 or 2 stage process blowers GR can be used for almost all technical gases and gas mixtures, , which may also be aggressive.  In all branches of industry. They are also ideal for gases with negative intake temperatures down to -30 °C.

DESIGN:

The conveying chamber sealed by

  • a) pressure relieved soft packings with purge gas connections,
  • b) pressure relieved carbon ring - labyrinth seals with purge gas connections,
  • c) double-acting mechanical seals, oil-purged
  • d) double-acting mechanical seals, water-purged

Drive shaft by radial seal ring.

DIRECTION OF FLOW:

Vertical, from top to bottom.

DRIVE:

Direct via flexible coupling or via flexibly coupled spur gear. Overhung via narrow v-belt (up to 250 kW driving power). Special materials: Depending on the particular operating conditions, models are also available in CrNi cast steel or with different coatings.
