Multi-stage Roots pumps

The optimal solution for clean and dry applications
Multi-stage Roots pumps by Pfeiffer Vacuum produce clean and dry vacuum for various applications and markets.

The technology of the multi-stage Roots pumps is the perfect solution here. Its frictionless working pumping module does not require lubricants and sealing material between the rotor and stator. Thus, hydrocarbon vapor back streaming can be avoided. In the suction chamber of the pumps, no sealing materials are processed. This means the pumps are free of particles, extremely reliable and stable for a long period of time which results in low costs of ownership.

Areas of usage for multi-stage Roots pumps in clean processes
Air-cooled multi-stage Roots pumps from the ACP series are very low maintenance and stand out with their constant performance. They are used in industrial or particle accelerator applications as well as in clean processes for semiconductor productio.
