Pfeiffer Multi-stage Roots Pump CV Version (ACP 28 / ACP 40)

CV versions extend the pure water vapor capacity up to 1,000 g/h (at 100 mbar and 30 °C ambient temperature). A high gas ballast flow warms up the pump and dilutes condensable gases (> 2 N.m3/h or 33 slm at 1 bar abs.). The external drainable silencer recovers liquid from the lowest point of the exhaust stage. A gas purge line injection device helps to protect lips seals and ball bearings from condensable vapors.
