0.7 Danger of Pump Damage
1
Do not use the pump for applications that produce abrasive or adhe-
sive powders or condensable vapors that can leave adhesive or high
viscosity deposits. Please contact Leybold Sales for selecting the right
separator.
2
Vapors which condense upon being compressed within the pump to
liquids must be avoided when their vapor pressure exceeds the vapor
tolerance of the pump.
3
Before pumping vapors, the RUVAC should have attained its operating
temperature. The pump will have attained its operating temperature
about 1 hour after starting the pump. During this time the pump
should be separated from the process by a valve in the intake line, for
example.
4
In order to prevent the transfer of vibrations from the RUVAC to other
parts of the system we recommend the use of corrugated hoses or
compensators on both the intake and the discharge sides.
5
Do not use the RUVAC pumps in combination with backing pumps
that have an ultimate pressure above 10 mbar. This prevents exces-
sively high temperatures of the RUVAC in idle mode operation.
6
The maximum cooling water pressure must not exceed 6 bar.
Otherwise there exists the risk of leaks.
7
In the case of wet processes we recommend the installation of liquid
separators upstream and downstream of the pump so as to avoid a
massive influx of liquid into the pump.
8
The discharge line should be laid so that it slopes down and away
from the pump so as to prevent condensate from backstreaming into
the pump.
9
The ingress of particles and liquids must be avoided under all circum-
stances.
10
Before installing, all flange covers must be removed.
11
The location where the RUVAC is installed must be selected such that
all controls are easily accessible.
12
In order to ensure an adequate supply of oil, the location at which the
RUVAC (including its accessories) is operated should be such that
angles over > 1° from the vertical are avoided.
