Gas sampling and gas conditioning technology 6-1.3.5-ME
12 COMMISSIONING
Prior to commissioning, system and process-specific safety measures must be observed.
For the media to be transported, the respective safety requirements and measures must be taken into
account.
Prior to using a medium, the compatibility of the materials of the pump head, diaphragm and valves
with the medium must be verified (for materials, see technical data).
The following steps must be carried out for commissioning:
The pumps must not start against pressure or vacuum. When the pump is switched on, the normal
atmospheric pressure must prevail in the pipes. This applies similarly during operation following a
brief interruption of power.
The maximum allowable working pressure (see technical data) must not be exceeded.
Restriction or regulation of the gas flow should only take place in the suction-sided pipe in order to
avoid exceeding the maximum allowable working pressure.
If restriction or regulation of the gas flow takes place on the pressure side, it must be ensured that
the maximum allowable working pressure of the pump is not exceeded.
With the pump stationary, normal atmospheric pressure must be established in the pipes.
Diaphragms and valve plates are the only wearing parts of the pumps. Wear is usually noticeable
by a considerable reduction in pneumatic power. Replacement must take place as described in
chapter 14ff.
Ambient conditions, see technical data.
For pumps used as vacuum pump and compressor:
Pressure and vacuum cannot be produced simultaneously.
WARNING!
The pumps must not be used in areas subject to explosion hazards
or for transporting a potentially explosive medium.
The transported medium must be safely discharged.
When connecting other components to the pump, the pneumatic
conditions must be observed (see 6.).
When connecting the pump to the electrical system, the relevant
safety requirements must be observed.
The standard internal thermal safety cut-out protects the pump
against overload. The pump automatically restarts after cooling
down. Hazardous situations constituted by this must be prevented
by suitable measures.
For the transport of aggressive or toxic media, the system-specific
safety requirements must be observed. Purging with air or inert gas
under atmospheric conditions is recommended prior to
decommissioning.
