Dry roughing pumps

ACP Series : The Adixen range of clean pumps

- No particulate contamination
Thanks to the frictionless design, there is no wearing parts in the path of pumped gases and therefore no particulate generation.

- No Hydrocarbon Vapors Backstreaming
ACP 15 series pumps are free of lubricant inside the pumping module;
giving benefit of no hydrocarbon vapors backstreaming.

- Constant Performances
Thanks to constant internal clearances and constant rotational speed (frequency converter driven motor) the ACP 15 pumps will provide:
- constant pumping speed
- constant ultimate pressure

- High Reliability
Thanks to the Alcatel expertise in the design of dry multi-stage Roots pumps, used in the most demanding applications.

- Low Maintenance Costs
Field serviceable, the ACP 15 series pumps require a complete overhaul only every 20 000 hours.


Typical applications

ACP 15/28/40 series standard version
- Analytical Instruments
. Electron microscopes
. Surface analysers
. Leak detectors
. Mass spectrometers
- R&D: particle accelerators, labs
- Industry: special lights bulbs
- Load-locks of clean processes

ACP 28/40 G version is specially designed for pumping traces of corrosive gases, with inert gas purge protecting the bearings.

G version is recommended for applications such as:
- Process monitoring
