The Leybold WSU1000 WSU-1000 Root's blower vacuum pumps are driven by an air-cooled canned motor, the term canned means that the blower's electric motor operates inside the pump's vacuum region. In the canned motor design, the motor's rotor operates on the drive shaft of the pump inside a vacuum-tight can made of a nonmagnetic material. The motor's stator slides over the outside of the vacuum tight can and operates in air. This canned electric motor design allows the WSU blowers to be particularly leak tight and operate without the need for shaft seal which would be subject to wear. For these reasons the Leybold WSU blower vacuum pumps are often used in vacuum processes which require evacuation of chemical process gases. The price for the pump listed is for a Leybold WSU 1000 blower booster vacuum pump only, backing pumps are extra. We also sell mechanical and blower vacuum pump systems.
