This Leybold Sogevac SV 40-65 BIFC 960463V Single-stage Rotary Vane Vaccum Pump is in great condition and was removed from a working environment. Please read carefully: We powered the unit with the supplied power cord to 240V 1PH 60HZ. The Vacon Frequency Converter that is installed on unit does not power on. It is unclear if the convertor is faulty or if we are misunderstanding the power requirements.  If the pump will be used in a 3 Phase facility, we imagine the converter would not be needed. Either way, this issue is reflected in the list price. We urge customers to view all photos as they show overall condition, included accessories and useful information. We will be happy to provide additional information as well as photos so please feel free to contact us with any questions.
