Recommended Maintenance Schedule
PERIOD TASK
Daily (with
the pump
running)
Check the bearing lubricating oil
level in the bearing housing
running sight glass and top up
oil if needed with 0.1 litres of oil.
Check the mechanical seal
lubrication oil level and top up if
required.
Check the bearing housing
temperature does not exceed
80degC.
Check visually for leaks.
Check for vibration.
Weekly or
170 hours (
with the
pump not
running)
Check security of all fasteners
and hose fittings.
Check bearing oil level in the fill
level sight glass.
Check and clean the magnetic
drain plug.
4 monthly or
2500 hours
Replace the bearing and
mechanical seal lubrication oil.
Annually or
8000 hours Replace the bearings, the drive
end lipseal and the mechanical
seal.
The above schedule is given for guidance
but site operating conditions may override
the
suggested maintenance intervals.
Adjustments to time scales will also have to
be made if the pump is idle for long periods.
For motor or engine maintenance and
maintenance of the priming system (when
fitted) refer to the separate operators
handbooks included within the pump
documentation pack.
6.2 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.
For diesel driven pumps disconnect the
negative battery lead to prevent inadvertent
starting.
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 bearing
housing and shaft assembly to a suitable
maintenance area.
It is important to ensure the suitable lifting
equipment is available and that the work is
carried out in a clean area.
6.3 Maintenance of the Mechanical Seal
The mechanical seal requires no
maintenance or adjustment when running.
Mechanical Seal Oil
Texaco Rando HD10 mineral oil
without EP additives.
Approx 7 litres for a complete fill.
6.4 Bearing Lubrication
a)
The pump incorporates a combination of
spherical roller and angular contact ball
bearings, lubricated by mineral oil that is
circulated by a flinger, to a gallery, and then
fed to the bearings.
b)
Bearing oil sump should be filled to the
centre of the sight glass when the pump is
cold and level. When running an oil level
should become visible in the gallery sight
glass after no more than three minutes, if it
does not then the sump oil level is too low
for the flinger to pick up. After the first run
the pump should be allowed to cool and the
level re-checked, a small amount of
additional oil may be required to replace the
oil retained in the gallery and bearings.
After first 50 hours drain off a sample and
check oil for contamination, change if
contamination is found.
c) Frequency of re-lubrication is dependant on
a number of factors, which can vary with the
application.
These include: operating
conditions, frequency and duration of
service, environment (humidity, dust & other
contaminants) and operating temperature.
The frequency of re-lubrication listed below
is therefore for guidance only and should be
modified to suit operating conditions.
Bearing Lubricating Oil
Texaco Rando HD68 mineral oil
without EP additives.
Approx 4 litres for a complete fill.
