Description
RUVAC roots pumps have been manufactured by Leybold Vacuum for many decades. The dry compressor roots principle has proven itself in many areas of vacuum technology. Combined with oil-sealed fore-vacuum pumps, RUVAC roots pumps are used very effectively to increase the pumping speed at low pressures, thus extending the operating pressure range of the fore-vacuum pumps.
RUVAC roots pumps are manufactured in three series with different motor drives. The RUVAC WA series uses air cooled, flange-mounted standard three phase motors. The RUVAC WS series are equipped with canned (rotor) motors in air-cooled or water-cooled versions.
Each series consists of various sizes to always provide an optimized pumping speed for each application. All three series are available with or without integrated bypass.
