Overview:
The Edwards HV8000 high vacuum mechanical booster has been developed to provide
high reliability operation in aggressive environments. With a nominal pumping speed of 7200 m3h-1 (4241 ft3 min-1) at 50Hz, it is ideal for large industrial and chemical applications.
Features & Benefits:
Performance
· Stable process for consistent output - suitable for continuous operation over wide pressure ranges on heavy duty large scale applications
Reliability
· No unplanned downtime - high performance water cooled mechanical shaft seal, large diameter shaft and large helical gears
Adaptability
· Easy integration and safe - optional water cooled exhaust gas after cooler, shaft seal safety purge, temperature monitoring and VFD available
Flexibility
· Configured to your needs - can be supplied with standard motor or without motor to allow a local motor to be fitted. Horizontal or vertical flow to suit application and system design
