Lobe Pumps
All pumps and equipment surfaces
which become hot, i.e. above 60°C
(140°F), during operation should
carry warning labels.
4.02 DAILY CHECKS
• Visual checks of all joints for signs of
leakage of product, flushing liquid (if
used) and oil from the gearbox.
• Listen and look for any unusual noises,
vibration or temperature change.
• If minor problems are identified these
should be rectified at the end of the shift
and if major they should be attended to at
once.
4.03 WEEKLY CHECKS
• As Daily Checks.
• Remove end cover of pump and inspect
for signs of damage or wear. Repair or
replace as necessary.
• If the main product shaft seals are of the
O-ring type or multi lip seal type inspect
them for signs of wear. Replace or plan
for replacement as necessary.
• Check lubrication level and top up as
necessary. This must be done with the
pump stopped.
• Check lubrication level on drive unit and
top up as necessary. Follow the
manufacturer's instructions.
4.04 MONTHLY CHECKS
• As Weekly Checks.
• Remove end cover and rotors and
inspect seal faces for wear and condition
of elastomers. Replace as necessary or
note for planned maintenance.
• If an end cover relief valve is fitted check
its function. If the relief valve is not
operating on a regular basis the
diaphragm may have a tendency to stick.
4.05 SIX MONTHLY CHECKS

• Check bearing wear by seeing if there is
any movement of the shaft side to side or
forwards and backwards. If movement is
perceived remove gear cover and
dismantle bearings for inspection,
replace if necessary.
• Drain and change oil in pump gearbox.
By ensuring a visual inspection daily and
regular checks at planned intervals, pumps
can be maintained to maximum
performance for many years.
