Teknik Bilgi

Proven Technology Fully Optimized RUVAC roots pumps have been manufactured by Leybold for many decades. The dry compressor roots principle has proven itself in many areas of vacuum technology. Combined with dry or oil-sealed forevacuum 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 available 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 valve (also known as pressure compensation valve).

• RUVAC roots pumps can be used either in vertical or horizontal position, thus ensuring flexibility in achieving compact design within systems. Position selected may be changed later if required.

• RUVAC roots pumps have rugged bearings, which in combination with the highly efficient lubrication systems enhances quiet running properties.

• The rotor and stator coils in the drive motor of the RUVAC WS and RUVAC WSU are separated by a vacuum-sealed can.

As there is no drive shaft leadthrough, the requirement for reliability combined with a perfect seal is met in an ideal manner. The canned (rotor) motors combined with the highly efficient lubrication system in the RUVAC WS series allow running speeds up to 6,000 RPM (with frequency converter). This means increased pumping speed with the same size of pump. The entire WA(U) range complies with the energy efficiency class IE3.
