Mehrstufige Wälzkolbenpumpen - Pfeiffer Vacuum

SH versions (ACP 28 / ACP 40)

The pump is designed for applications that require pumping of clean (dust-free) and non corrosive gases where presence of Fluorine is not permitted. SH pumps are equipped with a gas ballast device to improve pumping of light gases and avoid condensation vapors inside the pump. Three gas ballast options to satisfy customer needs.

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 50/6 0Hz, single-phase and three-phase
  • Standards: compliance with CE standards, UL/CSA certified, SEMI S2 certified

Product

  • Dry multi-stage Roots technology, SD versions, ACP pumps with a pumping speed of max. 28m3/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 22000 hours for ACP 28/40
  • No Fluorine backstreaming. Ideal for R&Daccelerator where NEG pumps are used.
