HV30000 Mechanical Booster PumpThe HV pump systems combine <strong>Edwards</strong> expertise in manufacture and assembly ofcomplete industrial vacuum systems with Dresser’s world-renowned Roots pumptechnology. These pumps are backed by <strong>Edwards</strong> Dry Pumps or Mechanical Boosterpumps.This range of high capacity mechanical booster pumps is designed to operate reliably forlong periods with no need for maintenance. The HV pumps can be fitted with an inverter toallow them to be started at atmospheric pressure, at the same time as the dry pumps.Features & Benefits●●●●●Water cooled shaft seals and after coolerFitted with thermal snap-switch, to protect the pump from overtemperatureNitrogen purge inlet fitted as standardVertical flow, direct drive (horizontal optional)Control with inverter, or interlock with a pressure switch inputDimensionsApplications●●●●●Semiconductor processing<strong>Vacuum</strong> distillation<strong>Vacuum</strong> packagingSteel degassingThin film coatingPerformance Curves8Page375(1) In their most efficient range, booster pumps(2) fill the gap between the pumping speeds of vapour diffusion pumps(3) vapour booster pumps(4) and rotary or dry high vacuum pumpsShop online at www.edwardsvacuum.com
