Dry compact Multi-stage Roots pump.
Clean vacuum. High reliability.
The multi-stage Roots pump technology of the ACP series meets the requirements of applications where clean and dry vacuum is needed.
No particle contamination
The frictionless pumping module is optimized to operate without internal lubricant and provides outstanding oil-free vacuum with no hydrocarbon vapor back streaming. Without any seals between rotor and stator no particles are generated.
High reliability
The absence of wearing parts inside the pumping module allows for unsurpassed long-term stability and high reliability in even the most demanding applications.
Constant performances
The frequency converter driven motor provides constant rotational speed, thus stable pumping speed and consistent ultimate pressure are achieved all over the world.
Low maintenance costs
Our ACP pumps require overhaul only every 22,000 hours of operation for the ACP 28/40 and 20,000 hours of operation for the ACP 15 resulting in low cost of ownership.
Condensable vapor ability
High flow gas ballast ports and drainable silencers allow the ACP to pump high amounts of condensable vapors (up to 1,000 g/h of pure water vapor).
