a31101985 - HV8000IND VF bareshaft

HV8000IND VF bareshaft



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 and Benefits

·  Stable process for consistent output - suitable for continuous operation over wide pressure ranges on heavy duty large scale applications
·  No unplanned downtime - high performance water cooled mechanical shaft seal, large diameter shaft and large helical gears
·  Easy integration and safe - optional water cooled exhaust gas after cooler, shaft seal safety purge, temperature monitoring and VFD available
·  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
