Preventing Leakage; Complete Unit; Pump Unit Delivered Without Motor / Without Sensors; Coupling Guard - salmson NOLH Installation Et Mise En Service

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 WITHOUT 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
CREATION
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 CREATION
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.
All manuals and user guides at all-guides.com
TO AVOID HAZARD

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.
