Model GM ... dz - Direct-Drive High-Pressure Positive Displacement Blowers

From

0

The direct-drive GM ... dz blowers from AERZEN are high-performance machines. 1 or 2 stage design, with separate pressurised oil lubrication for the oil-free transport and compression of air, neutral gases, and gas mixtures. Highly advanced and extremely robust Roots-type products. Available in a wide range of special materials and seals, such as stainless steel or as acetylene boosters according to TRAC norms.

Design

  • Housing with circular flanges and o-ring seals, lube- and purge oil supply by complete oil unit, oil chambers under gas pressure.

Shaft Sealings

  • Conveying chamber by combined oil slinger piston ring labyrinth seals with condensate chamber between the piston rings or shaft seal ring - piston ring labyrinth seal.
  • The drive shaft is sealdes via compressed-oil-purged double-acting mechanical seal.
