Edwards GV250 Industrial DRYSTAR Vacuum Pump - REBUILT

The DRYSTAR® GV80 – 600M range is based on the well proven Edwards reverse claw mechanism reaching a peak speed of 560 m3h-1 / 330 ft3min-1. The reverse claw mechanism results in short gas paths within the operating mechanism, providing the ability to handle large amounts of dust and water vapor, when compared to oil sealed pumps, without deterioration of performance. The GV range is able to handle large amounts of dust and water vapor with little or no effect on performance. Advantages to this include:

  • Low cost of ownership in harsh conditions
  • High reliability – dry mechanism proven in 100,000 installations
  • Oil free mechanism – reduced maintenance
  • Higher dust and water vapor tolerance
  • Accessories to optimize pump performance to process variables
  • Fast pump down with Edwards hydrokinetic drive booster pumps.
