2.9.3 BUILD UP OF EXPLOSIVE MIXTURE
Ensure that pump casing and mechanical seal chamber are
correctly vented and that pump will not run dry.
Make sure that the pump runs with filled-in suction and discharge
lines to avoid build up of an explosive atmosphere. In addition it is
essential that auxiliary sealing systems are properly filled.
To avoid potential hazards from fugitive emissions of vapor or gas
to atmosphere the surrounding area should be correctly
ventilated.
2.9.4 PREVENTING LEAKAGE
The pump must only be used to handle the liquids for which
it has been defined.
If the pump is installed outdoor, make sure liquid containing parts
are drained and/or protected against freezing.
If leakage of liquid to the atmosphere can result in a hazard then a
leakage detection sensor should be installed.
2.9.5 COMPLETE UNIT
ATEX certification for a complete unit according to ATEX
Directive 94/9/CE is given according to lower protection
level of the integrated component. This comment applies
particularly to the electric motor protection.
2.9.6 PUMP UNIT DELIVERED W ITHOUT
MOTOR / WITHOUT SENSORS
If a partial delivery is required (electric motor, flexible
coupling, coupling guard or sensor not supplied), an
integration certificate will be established.
It will be the integrator’s responsibility to supply missing parts in
order to fulfill ATEX requirements for the complete machine.
2.9.7 COUPLING GUARD
The coupling guard used in a potentially ATEX atmosphere
shall meet following requirements :

Consist of non-sparking material (e.g brass),

Must be made of antistatic material,

Must be designed in such a way that the rotating parts
will not come in contact with any part of the guard after a choc.
2.9.8 MAINTENANCE TO AVOID HAZARD
When a pump is used in a potentially ATEX atmosphere it is
necessary to check regularly the following parameters and
respect a maintenance plan to ensure that the equipment runs in
perfect technical conditions.
Following regular checks are mandatory :

No leakage of the shaft seal,

Ball bearings temperature (on bracket housing
surface),

No cavitations and no abnormal running noises,

Correct position of isolating valves and function of
motorized valves.
If some parts are worn or working in bad conditions the pump
must be stopped immediately and put in safety until maintenance
operations are performed. Origin of default(s) should be
eliminated.
2.9.9 PREVENTING SPARKS CRE ATION
Necessary measures must be taken to avoid sparks creation in
case of external impact.
Base plate and pumpset elements must be properly grounded.
Ensure continuity between components of the group.
It applies to :
-
Pump hydraulics,
- Coupling guard,
- Motor frame,
- Baseplate.
The threaded hole or the earthing plate located on the base plate
should be used to make proper earthing.
3 TRANSPORT AND STORAGE
3.1 SAFETY MEASURES
Never rest below a suspended load.

Keep a safe distance while the load is being
transported.

Check equipment weight and choose slings and other
lifting devices accordingly. Lifting equipments should be in good
conditions.

Adjust the length of the lifting devices so that pump
or/and pumps set is moved horizontally.

Lifting lugs or eyebolts that are sometimes attached to
the pump or to the motor should not be used to lift a complete
pump set. They should be used only to lift pump parts during
dismantling operations.

Use the lifting points that are mentioned on the pump
set or refer to following information.
3.2 DELIVERY
After reception of goods, the delivered items must be
inspected for damage. Check that all parts are present
(check description and quantities against delivery/shipping
documents). If any parts are damaged, missing or if transportation
damage is visible, this should be noted on the freight
documentation or on the delivery note.
Do not separate attached documentation from the pump.
Unpack the good and eliminate packaging according
environmental requirements.
Do not remove caps from pump flanges if pump will not be
installed immediately.
3.3 SHORT TERM STORAGE
Leave piping connection caps fastened to keep dirt and
foreign material out of pump casing during storage.
If the pump will not be used immediately after delivery, it
must be stored in a temperate, dry, ventilated location and
away from vibrations. Turn the pump shaft at intervals (every
month) to avoid brinelling of the bearings and the seal faces from
sticking. Close protective packing when done.
If stored as described above, the pump can be stored up to 6
months.
Consult SALMSON for preservative procedure when a longer
storage period is required.
3.4 HANDLING
Depending on their design some pumps can fall over before
they are definitively fastened to the floor. Take all
necessary actions to ensure that no-one can be crushed while the
equipment is moved.
A crane must be used to lift all equipment exceeding 25Kg.
Palettes, crates or boxes can be moved or unloaded by
using a fork-lift truck or a hoist depending on lifting devices
available on site. Only suitable lifting gear and load carrying
equipment with valid test certificates and adequate lifting
capacity for the loads involved should be used to lift and carry the
goods. Only authorized personal should proceed to pump
transportation and they must respect local regulations. Weight of
goods is indicated on the delivery note.
Only use suitable lifting points that are indicated on the
equipment and respect hereafter lifting and transportation
sketches. Pumps should never be lifted directly with slings. Hooks
must be used and placed in dedicated lifting holes. Chose proper
sling length or use a lifting beam.
