Edwards GV80 Dry Vacuum Pump, 230/460 V, 60 Hz, NR8031000R, GV-80
Edwards GV80 Overview:
The Edwards GV 80 pumps are rugged, reliable dry vacuum pumps designed for general vacuum use.
The Edwards GV80 / NR8031000R pump is a three-stage, positive displacement rotary pump in which pairs of intermeshing rotors (mounted on common shafts) are held in correct phase relation by a pair of timing-gears. The timing-gears and the adjacent double-row angular contact ball-bearings are oil lubricated.
The Edwards GV80 pump has lifting-bolts and is mounted on a robust frame. Fixing holes in the frame can be used to secure the pump frame in its operating position.
The GV80 / pump has a shaft-seals purge system and a gas-ballast system.
You can connect a dry compressed air supply to the shaft-seals purge inlet. The shaft-seals purge pipeline then delivers the dry air purge to the shaft-seals. This dry air purge: ensures that the shaft-seals are maintained at a positive pressure during pump operation; prevents the entry of corrosive or toxic process vapours into the pump gearbox; prevents contamination of the process gases by pump oil; prevents damage to the shaft-seals by debris.
As supplied, the gas-ballast system can deliver ambient air to the pump gas-ballast inlet. The air-flow is filtered and is controlled by a valve. A check-valve in the system prevents the escape of process gases out of the gas-ballast system into the local atmosphere.
If required for your application, you can connect dry nitrogen supplies to the pump, to deliver nitrogen gas-ballast and nitrogen shaft-seals purge instead of air.
