The following hazards may arise during
maintenance work:
Fluid Pressure Jet Hazards
Check and ensure that the pump
operates at below the Maximum
Working Pressure specified in the manual or
on
the pump nameplate and before
maintenance, ensure that the pump is drained
down.
Hazardous Materials
Wear a suitable mask or respirator
when working with packing or gasket
components that contain fibrous material, as
these can be hazardous when the fibrous dust
is inhaled. Be cautious, if other supplier's
components have been substituted for
genuine SPP Pumps Ltd parts, these may
then contain hazardous materials.
Hazardous Gases, Mists, Sprays
and Leaks
Be aware of the hazards relating to the
pumped fluid, especially the danger from
inhalation of noxious and toxic gases, skin and
eye contact or penetration. Obtain and
understand
the hazardous substance
(COSHH) data sheets relating to the pumped
fluid and note the recommended emergency
and first aid procedures.
BEFORE ATTEMPTING ANY MAINTENANCE ON
A PUMP, PARTICULARLY IF IT HAS BEEN
HANDLING ANY FORM OF HAZARDOUS LIQUID,
ENSURE THAT THE UNIT IS SAFE TO WORK ON.
THE PUMP MUST BE FLUSHED THOROUGHLY
WITH A SUITABLE CLEANSER TO PURGE AWAY
ANY OF THE PRODUCT LEFT IN THE PUMP
COMPONENTS. THIS SHOULD BE CARRIED OUT
BY THE PLANT OPERATOR AND A CERTIFICATE
OF
CLEANLINESS OBTAINED BEFORE
STARTING WORK. TO AVOID ANY RISK TO
HEALTH IT IS ALSO ADVISABLE TO WEAR
PROTECTIVE CLOTHING AS RECOMMENDED
BY THE SITE SAFETY OFFICER, ESPECIALLY
WHEN REMOVING OLD SEALS OR GASKETS
THAT MAY BE CONTAMINATED.
6.1
Preparation for Maintenance
Electric Shock & Accidental
Starting Hazard
ISOLATE the equipment before any
maintenance work is done. Switch off the
mains supply, remove fuses, apply lock-outs
where applicable and affix suitable isolation
warning signs to prevent inadvertent re-
connection.
In order to avoid the possibility of maintenance
personnel inhaling dangerous fumes or
vapours. It is recommended that maintenance
work be carried out away from the pump
location by removal of the motor and shaft
assembly to a suitable maintenance area.
No special tools are required for dismantling
and re-assembling, however, it is important to
ensure the suitable lifting equipment is
available and that the work is carried out in a
clean area.
6.2 Maintenance of Mechanical Seals
Generally there is no maintenance required on
mechanical seals, they should be replaced if
leakage occurs.
6.3 Dismantling and reassembly:
6.3.1 General
If the pump is maintained and serviced
regularly, breakdowns that require the pump to
be dismantled; should not occur.
If a fault occurs, the cause should be identified
before dismantling. Refer to Section 7 - Faults
and Remedial Action.
Refer to Section 8 - for the Pump Section
Drawing for your pump.
When the pump is being dismantled, parts
must be handled with care, to avoid damage
by dropping and hammer blows.
