Refurbished Leybold WA/WAU2001 Series Booster Pump
The Leybold WA2001 and WAU2001 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 “A” designation indicates the booster is equipped with a direct drive TEFC motor, which is a good choice for general use where potentially harmful gases are not present. The WA2001 is a non-bypass design and requires a pressure switch to engage the booster, whereas as the WAU2001 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.
