iH1000 Dry Pump 460V, 60 Hz 3Ø



Edwards advanced semiconductor vacuum pumps have been field-proven to perform to the highest operating standards. Reliability and high performance are achieved by extending service life, improving uptime and increasing productivity, while minimizing footprint and cost of ownership.
The iH Series offers high reliability for difficult processes, such as PECVD and LPCVD, where particulate, condensable and corrosive by-products are present.


The iH system operates at pressures between atmospheric and ultimate vacuum with no lubricating or sealing fluid in the pumping chamber. This ensures a clean pumping system without back-migration of oil into the system being evacuated. 
The iH1000 system has an HCDP80 dry pump, with an HCMB1000 mechanical booster pump fitted to the inlet of the HCDP80 pump. Both the HCDP and HCMB pumps have enclosed, water-cooled motors. The iH system is therefore suitable for applications in clean environments where fan cooling of motors is unacceptable.
The iH system has a gas system which introduces purge gas into the HCDP pump. This gas system is suitable for use on harsh duty processes. If you use the iH system on light or medium duty processes, you can use the economiser gas mode to reduce the consumption of purge nitrogen by the pumping system.
You can manually control the iH system through the Pump Display Terminal. Alternatively, you can use your process tool or other control equipment to control the operation of the iH system through an Interface Module or through an iM Communications Module accessory or you can use the iH Single Equipment Monitor accessory to control the operation of the iH system.

Features and Benefits

  • Optimized utilities consumption.
  • No preventative maintenance required.
  • Cantilevered shafts and specially profiled rotors for better handling of particles.
  • Reserve motor power also maximizes reliability on harsh-duty CVD applications.
  • Corrosion resistant materials allow pumping of corrosive gases.
  • Higher operating temperatures provide ample margin to prevent gas condensation.
  • The one-piece shaft eliminates the need for a motor coupling and a fifth pumping stage removes the need for a silencer and eliminates particle accumulation, both reducing the overall footprint.
