Root blowers with air-cooled hermetically canned motor
Leybold RUVAC WS roots blower is driven by air or water-cooled canned motor. The available frequency converters have been matched to the pump so that the possibility of mechanical overloading it is excluded. In the case of a pressure difference which is too high, the rotational speed of the pump is automatically reduced until its load. Roots vacuum pumps of the series RUVAC WSU are provided with an additional integrated pressure equalization line and a differential pressure valve. Pumps from these series are supplied with a vertical pumping action as standard.
Supplied Equipment
- The required quantity of oil is supplied separately with the pump (exceptions from this are indicated)
- If no other type of oil is stated, then mineral oil LVO 100 is used as standard
- Purged with nitrogen for corrosion protection
- Gasket in the intake flange with integrated dirt sieve
Roots vacuum pumps of the series WAU/WSU/WHU are provided with an additional integrated pressure equalization line and a differential pressure valve.
