EBARA Multi-Stage Dry Vacuum Pumps Overview
Depending on the process, a complete pump overhaul is recommended every 1-2 years
as a means of ensuring trouble-free performance. During overhaul service, all
bearings, labyrinth seal rings, and O-rings are replaced; coolers are cleaned or
exchanged, and the pump internals area cleaned, wet bead finished and vacuum
baked. The overhaul requires 1-2 weeks to complete, not including shipping to and
from the service center. Exchange pumps are available upon request. Contact your
Ebara representative for further details.
