The Leybold RUVAC WS1000 Root's blower vacuum pump is a Single Stage Roots Pump and 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 WS 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 WS blower vacuum pumps are often used in vacuum processes which require evacuation of chemical process gases.

The WS pumps are easy to operate! For Start up Procedures See Section 2-9 in the Operation Manual.pdf manual at Downloads to the side of this ad.
