Negative pressure stage blowers with two- or three-lobe blower technology for plant engineering for forced conveyance at extreme negative pressure up to 80% vacuum. Oil-free and extremely robust. Belt or direct drive version. For stationary and vehicle application.

Design

  • Housing with additional third socket on suction side for pre-inlet cooling
  • series GM . . . Sm with lube oil supply by splash lubrication. 6 sizes, intake volume flow 60 up to 16.000 m³/h
  • for an absolute pressure at inlet of approx. 200 mbar against atmosphere.
  • series GM . . . Lm with central oil circulating lubrication. 3 sizes, intake volume flow 16.000 up to 50.000 m³/h for an absolute pressure at inlet of approx. 400 mbar against atmosphere

Shaft sealings

  • The conveying chamber is sealed by means of an oil slinger in combination with 4 piston ring labyrinth seals with a central vent chamber.
  • The drive shaft is sealed by double radial seal rings with grease barrier.

Direction of flow

  • Vertical, from top to bottom.

Drive

  • Direct coupling with motor or via spur gear resp. narrow v-belt drive up to size 19 for all loads.

Special material

  • Available in nodular graphite cast iron (EN-GJS-400-15 resp. EN-GJS-400-18).

Applications
