Installation and commissioning
5.1 Installation and transport
All installation work on a pump or pump unit must not take place in an explosive
atmosphere. The operating company must ensure that no explosive atmosphere is
present during installation. Before installation and commissioning, check if any parts
have been damaged during transport. Transport safety devices and protective foils
must be removed.
The machine may not be put into operation in the event of visible transport damage. In
such a case, contact Fristam Pumpen.
Special Atex carriages are designed for the transport of Atex pump units. This
sufficiently minimizes the risk of a potential ignition source arising during transport. The
risk of the formation of a potential ignition source cannot be completely excluded,
therefore a pump unit on a carriage should
never
be transported in an explosive
atmosphere.
The operating company is responsible for ensuring that no parts, components, or
devices are transported as long as there is an explosive atmosphere present.
Danger of explosion due to incorrect installation!
- Applicable explosion regulations and information on the rating
plates of the equipment must be checked.
- The operating company must ensure that the pump and motor have
sufficient clearance for sufficient air circulation.
- Sufficient space must be available for inspection and maintenance
work.
- Forces, shocks and vibrations transmitted to the pump from
outside, e.g., due to braced pipes or loading of covers and
enclosures, are not permitted, as they can cause parts inside the
pump to start up or protective devices to become ineffective, which
can contribute to an increased risk of ignition.
- Incorrect installation influences the filling, venting and draining of
the system and can lead to inadequate lubrication of the seals
during operation.
- The foundation must be level and sufficiently dimensioned for the
weight of the unit.
- The operating company must ensure that the pumping medium
does not flow back after the pump has been switched off.
