Pfeiffer ACP 15 – Air-Cooled, Multi-Stage Root Pump (Standard, Single Phase, Manual Gas Ballast)

• ACP 15, standard, single-phase, manual gas ballast
• Dry multi-stage Roots technology, SD versions, ACP pumps with a pumping speed of max. 15 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)

Multi-stage Roots Pumps for Light-Duty Applications

Dry pumps for light-duty processes

Based on the proven technology of the dry multi-stage roots pumps, Pfeiffer Vacuum offers a wide selection of pumps for light-duty processes. The most important characteristics of pumps in these applications are constant performance during pump lifetime and robustness as well as high reliability.

Air-cooled multi-stage Roots pumps from the ACP series

The multi-stage Roots pumps of the ACP series are designated for oil- and particle-free applications in the pressure range between atmospheres up to 3 · 10-2 hPa. The air-cooled pumps are the optimal replacement for rotary vane pumps.

SD versions (ACP 15 / ACP 28 / ACP 40)

The pump is designed for applications that require the pumping of clean (dust-free) and non-corrosive gases. Standard pumps are equipped with a gas ballast device to improve the pumping of light gases and avoid condensation vapors inside the pump. Three gas ballast options to satisfy customer needs.

Light duty processes require more and more a clean and dry vacuum. The multi-stage Roots pumps by Pfeiffer Vacuum are the ideal solution for industrial and Research & Development applications as well as for back-end and process monitoring in the semiconductor market.

No particle contamination

The frictionless pumping module is optimized to operate without internal lubricant and provides an outstanding oil-free vacuum with no hydrocarbon vapor back streaming. Without any seals between the rotor and stator, no particles are generated. ACPs provide hydrocarbon and particle-free really clean vacuum.

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 a 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).
