Multi-stage Roots Pumps - Pfeiffer Vacuum

CV versions (ACP 28 / ACP 40)

CV versions extend the pure water vapor capacity up to 1,000 g/h (at 100 mbar and 30 °C ambient temperature). A high gas ballast flow warms up the pump and dilutes condensable gases (> 2 N.m3/h or 33 slm at 1 bar abs.). The external drainable silencer recovers liquid from the lowest point of the exhaust stage. A gas purge line injection device helps to protect lips seals and ball bearings from condensable vapors.

Customer value

  • Air cooling: no water supply required
  • Frequency inverter: hour meter, remote operation mode (RS-485, dry contacts, Profibus on request), multiple rotational speed selection (power saving, noise reduction, adaptation to application cycle)
  • Universal power supply: wide voltage range 50/60 Hz, single-phase and three-phase
  • Standards: compliance with CE standards, UL/CSA certified, SEMI S2 certified

Product

  • Dry multi-stage Roots technology, CV versions, ACP pumps with a pumping speed of max. 28 m3/h
  • No particle contamination, thanks to frictionless design: no wearing parts in the pumped gases path
  • No hydrocarbon vapors backstreaming: ACP series pumps are free of lubricant inside the pumping module
  • Constant performances (Pumping speed, max. and ultimate pressure)
  • High reliability: thanks to our expertise of dry multi-stage Roots pumps since 1988
  • Low maintenance costs: no annual field service, complete overhaul only every 22,000 hours for ACP 28/40
  • Condensable vapor ability: with gas ballast ports and drainable silencer. ACP series pumps can handle up to 1,000 g/h of pure water vapor.
