Advantages to the User
- Oil immersed radial shaft seals
made of FPM (FKM) for sealing
against the atmosphere
- Use of universal IEC motors
(50/60 Hz)
- The motors fulfil in Europe (50 Hz)
the efficiency requirements in accordance
with EFF1
- In the USA (60 Hz) the motors are
UL approved and fulfil the efficiency
requirements in accordance with
EPAC
- If required with external pressure
equalisation 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
Typical Applications
- Large vacuum systems like sintering
and annealing furnaces which require
multi-stage pumpsets
- In large vacuum rectification
systems Roots vacuum pumps with
postcondensers for compressing of
vapors
Custom Pumps
- 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 m 3 /h to
2000 m 3 /h (147.3 to 1178 cfm)
Technical Note
