RUVAC WA/WAU Roots Vacuum Pumps with Air-Cooled Flange-Mounted Motors

Advantages to the UserTypical ApplicationsSupplied Equipment
- Two air-cooled series, each with four models
- Reliable and trouble-free
- Sealing rings with their housing can be readily replaced
- Shaft seals and elastomer seals made of FPM/Viton
- Air-cooled standard motors in accordance with IEC dimensions eg. NEMA dimensions
- Easy to exchange with custom motors
- Integrated pressure equalization line for protection against overloading at high pressures on WAU models
- Pumping direction may be changed as required
- ATEX versions compliant to 94/9/EC possible
- 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
- RUVAC WA/WAU are supplied as standard for a vertical pumping action, horizontal pumping action upon request
- Mineral oil N 62 is used as standard
- Gasket in the intake flange with dirt sieve
- The required oil filling is included in separate bottles
