Our specialist service personnel can help with
preventative maintenance records and provide
condition monitoring for temperature and vibration to
identify the onset of potential problems.
If any problems are found the following sequence of
actions should take place:
a) Refer to section 7, Faults; causes and remedies,
for fault diagnosis.
b) Ensure equipment complies with the
recommendations in this manual.
c) Contact Flowserve if the problem persists.
If the problem renders the equipment in-
operational, the following safety precautions
must be taken:
- ensure that persons and equipment are
protected by applying the pre-defined
procedures together with the health and safety
department.
- have the work carried out by properly trained
and competent staff.
6.2.1 Standard maintenance
For all maintenance work on the pump,
refer to the standard instructions if the pump type
used is different to that indicated below.
Roller bearing
6.2.1.1 MEN, MEN-TI and MHP pumps:
End bearings are factory-lubricated for life.
They require no maintenance.
6.2.1.2 ME-TI pump
:
The bearings fitted are pre-packed with grease at
the factory. When the re-greasing period is reached
it is necessary to remove as much of the old grease
as possible with a clean lint free cloth and repack
the bearings with fresh grease.
If a check shows a bad running of the
motor pump unit, the user must:
- Refer to the "fault finding chart" chapter 7 of this
leaflet to apply the recommended solutions.
- Ensure that your equipment corresponds to the
arrangements of this leaflet.
- Contact FLOWSERVE after-sales Department if
the problem persists.

6.2.2 Gland packing
6.2.2.1 Pump fitted with a packed gland
A well run in and correctly adjusted packing gland
requires little maintenance.
If, after some time, the leakage becomes too great,
the gland should be tightened again in order to
return these to a normal level.
If re-tightening is not possible, new packing must
be installed
6.2.2.2 Gland packing inspection and removal
a) Remove the shield guards
b) Slide back the gland
c) Remove the packing rings with an extractor
designed for this purpose (including the lantern
ring if it exists; note its position and its direction of
rotation).
d) Inspect the state of the sleeve surface (except
for ME-TI and MEN-TI pumps); the presence of
many marked grooves will indicate that it must be
replaced.
e) Carefully clean the different pieces of the
packing gland.
