SH / R 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. ACP R version is based on SH pump design and is equipped with remote frequency converter. The possibility to remove the frequency converter is important when the pump is installed close to radiations. Detached frequency converter can be installed up to 100 meters away from the pump.

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, SH versions, ACP pumps with a pumping speed of max. 40 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 22000 hours for ACP 28/40
  • No Fluorine backstreaming. Ideal for R&D accelerator where NEG pumps are used
