Diaphragm pump N630 EX Installation and connection
Translation of Original Operation and Installation Instruction, english, KNF 320945 04/21 29
– the cables do not come into contact with movable or hot parts.
– the cables cannot be worn or damaged on sharp corners or edges
– no tensile and pressure forces are exerted on the connection point
of the cables (strain relief)
PTC thermistor sensor
The motors are equipped standard with PTC thermistor sensors for
monitoring against overheating (see operating instructions for mo-
tor).
The three-phase motors are suitable for operation with frequency
converters (see operating instructions for the motor).
7.3 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
4
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.
WARNING
Risk of explosion during pressure limitation result-
ing from the medium mixing with the environment
à
Make certain that there is no risk of explosion
posed by the medium mixing with the envi-
ronment.
Pump discharge à
If the pump is used as a vacuum pump, safely (with respect to medium
and noise) drain the hot pump discharge that may, under certain cir-
cumstances, occur at 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.
