Product Description

The series WA/WAU Roots vacuum pumps are provided with directly flange-mounted air-cooled standard three-phase motors. The oiled radial sealing rings of the RUVAC WA/WAU for sealing the shaft against the atmosphere are made of FPM (FKM) (fluorpolymer).
Roots vacuum pumps of the series WAU/WSU/WHU 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.

Design Principle

Roots vacuum pumps, which are also called Roots blowers, are rotary plunger-type pumps where two symmetrically shaped impellors rotate in opposite directions inside the pump housing.
The figure-of-eight rotors are synchronized by a gear which ensures that the impellors are counter-rotating in such a way, that they are near to one another and to the housing without actual contacting.
In rotor positions I and II (see figure on the left) the volume of the intake is increased. As the rotors turn further to position III a part of the volume is cut off from the intake side.
In position IV this volume is opened to the exhaust side and gas under fore vacuum pressure (higher than the intake pressure) flows in. This gas compresses the gas coming from the intake. As the rotors turn further the compressed gas is ejected through the exhaust flange.
This process repeats itself twice for each rotor per full turn.
As the rotors do not come into contact with the pump's housing Roots vacuum pumps may be operated at high speeds. Thus a high pumping speed is obtained from comparably small pumps.

 

Advantages to the User

- Two air-cooled lines WA/WAU, each with four pump sizes
- Motors of efficiency class IE 2 (WA/WAU 2001: efficiency class IE 3)
- Reliable and trouble-free
- Sealing rings with their housing can be readily replaced
- Shaft seals and elastomer seals made of FPM (FKM)/Viton
- Easy to exchange with custom motors
- Integrated pressure equalization line for protection against overloading at high pressures on WAU models
- Conversion from vertical to horizontal pumping action can be done from the side of the customer
- All WA(U) pumps comply as standard with ATEX Cat. 3i
- Depending on requirements, motors from different ATEX categories can be fitted

 

Backing Pumps
The backing pumps listed in the following are recommended for connection to the RUVAC Roots vacuum pumps:

Rotary vane vacuum pumps	Dry compressing screw vacuum pumps
TRIVAC B with pumping speeds between 16 and 65 m^3 x h^-1 (9.4 and 38.3 cfm)	SCREWLINE SP 250 and SP 630 with pumping speed of 250 and 630 m^3 x h^-1 (147.3 and 371 cfm)
SOGEVAC with pumping speeds between 16 and 1200 m^3 x h^-1 (9.4 and 707 cfm)	DRYVAC with pumping speed of 450 to 3800 m^3 x h^-1 (265 and 2238 cfm)

Benefits:
- directly adaptable
- smallest system
- smart control
 

Applications Examples

- For oil-free compression of gases and vapors in combination with a backing pump
- Short cycle pumping processes also in the presence of large quantities of gas and vapor
