Blower Power For Special Requirements
The 1- or 2-stage process blowers GR can be used variably for almost all technical gases and mixed gases. In all industrial sectors. Ideal also for gases with negative intake temperatures down to -40 °C. The process gas blower type GR can also be used to convey aggressive gases Maximum pressure increase of 1.5 bar, maximum pressure 6 bar g
Design
The conveying chamber is completely separated from the oil sumps by a space open to atmosphere.
- Maximum pressure increase of 1.5 bar
- Maximum pressure 6 bar (g)
Shaft Seals:
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 og flow:
Vertically downwards.
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 nodular graphite cast iron or CrNi cast steel.
