6.3 Pneumatic connection
CAUTION
Personal injury or property damage through
ejected plugs
If not removed, the plugs on the pressure side of
the pump can be ejected during operation by the
resulting overpressure.
à
Remove the plugs during installation.
à
Wear appropriate personal protective equip-
ment.
Connected components
à
Only connect components to the pump that are designed for the pneu-
matic data and thermal requirements of the pump. (see Chapter
3
Technical data ).
Pressure relief device
à
Protect the compressors by means of a pressure relief device between
the pressure-side connections of the compressor and the first shut-off
valve.
Pump discharge
à
If the pump is being used as a vacuum pump, safely (relating to the
medium and noise) discharge the possibly hot pump discharge via the
pneumatic outlet of the pump.
Decoupling
à
KNF recommends mechanically decoupling the pump from the pipe
system, e.g., through the use of flexible hoses or pipes. In this way it is
possible to prevent the transfer of possible pump vibrations and noises
to the system.
Connecting the pump
A marking on the pump head indicates the flow direction.
CAUTION
Risk of injury from mixing up suction side and
pressure side
Mixing up the suction side and pressure side can
result in breakage of connected components on
the suction side and pressure side.
à
Observe the marking of inlet and outlet on
the pump head.
1. Remove the protective plugs from the hose connection threads.
2. Connect the suction line and the pressure line (for mounting dimen-
sions, see Chapter 3 Technical data ).
3. Lay the suction line and pressure line with a descent so that no con-
densate can run into the pump.
Pneumatic noises can be reduced or dissipated by using a silencer
(see Chapter
10.2 Accessories ).
NOTICE
Secure the pressure-side connections with a fas-
tener (e.g., hose/pipe clamp) to prevent the hoses
from slipping down from the connection.
