G versions (ACP 15 / ACP 28 / ACP 40 / ACP 90)

G version pump is compatible with trace amounts of corrosive gases. Three jets located in the purge line help withstand trace amounts of corrosive chemicals, protect the low and high pressure ball bearings. For optimal ball bearing protection, the neutral gas pressure must be set to 0.3 bar (relative pressure) according to the flow rate value provided in technical data.

Customer value

  • Air cooling: no water supply required
  • Frequency converter: 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

  • Oil-free multi-stage roots pumps of the ACP series, G versions, with a max. pumping speed of 15 m3/h
  • No particle contamination, thanks to frictionless design: no wear parts in the path of the pumped gases
  • No backflow of hydrocarbon vapors: ACP series pumps are lubricant-free inside the pumping module
  • Constant performance (pumping speed, max. continuous inlet pressure and final pressure)
  • High reliability: thanks to our expertise with oil-free multi-stage roots pumps since 1988
  • Low maintenance costs: no annual field service, complete overhaul only every 20,000 hours for ACP 15
  • The pump is compatible with traces of corrosive gases. A purge gas stream dilutes the corrosive media.
  • Dry multi-stage Roots technology, G 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)
