RUVAC RA Roots Vacuum Pumps with Flange-Mounted Motors
| Advantages to the User | Typical Applications | Custom Pumps | Technical Note |
|
- Oil immersed radial shaft seals
made of FPM for sealing against the
atmosphere - Use of universal IEC motors (50/60 Hz) - The motors fulfill in Europe (50 Hz) the efficiency requirements in accordance with EFF1 - In the USA (60 Hz) the motors are UL approved and fulfill the efficiency requirements in accordance with EPAC. - If required with external pressure equalization line and differential pressure valve so that the pump may be switched on jointly with the backing pump at atmospheric pressure - Motors can easily be exchanged for special voltage motors. Explosion protected motors and motors for special main frequencies upon request - Over-temperature switch in the stator coil of the motor - Rugged dry compressing vacuum pump - Most reliable even under rough operating conditions - ATEX versions compliant to 94/9/EC possible |
- Large vacuum systems like sintering
and annealing furnaces which require
multi-stage pump sets - In large vacuum rectification systems Roots vacuum pumps with post condensers for compressing of vapors |
- If required the RA pumps are also
available as C versions (chemical
versions) - Pumps made of special materials may be specified as well as pressure burst resistant pumps - Custom designed pumps for pumping speeds of 250 m3/h to 2000 m3/h (147.3 to 1178 cfm) |
For operation ordering of oil is necessary |
