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.
2.8.10

MAINTENANCE TO AVOID HAZARD 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.
2.8.11

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.

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 us 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.
