Refurbished Leybold WS/WSU2001 Series Booster Pump
The Leybold WS2001 and WSU2001 are Roots type blowers and are part of Leybold’s RUVAC series of blowers, all of which are equipped with labyrinth oil sealing technologies making them incredibly robust across a wide range of applications. The “S” designation indicates the booster is equipped with a canned motor, which is a good choice for applications where harmful gases may be present. The WS2001 is a non-bypass design and requires a pressure switch to engage the booster, whereas as the WSU2001 is equipped with a bypass valve (“U” designates this) for improved pumping from atmosphere. Both models can be installed in either a vertical or horizontal orientation without internal modification.
