On completion of work all guards and safety devices
must be re-installed and made operative again.
Before restarting the machine, the relevant
instructions listed in section 5, Commissioning, start
up, operation and shut down must be observed.
Oil and grease leaks may make the
ground slippery. Machine maintenance must
always begin and finish by cleaning the ground
and the exterior of the machine.
If platforms, stairs and guard rails are required for
maintenance, they must be placed for easy access to
areas where maintenance and inspection are to be
carried out. The positioning of these accessories
must not limit access or hinder the lifting of the part to
be serviced.
When air or compressed inert gas is used in the
maintenance process, the operator and anyone in the
vicinity must be careful and have the appropriate
protection.
Do not spray air or compressed inert gas on skin.
Do not direct an air or gas jet towards other people.
Never use air or compressed inert gas to clean
clothes.
Before working on the pump, take measures to
prevent the pump from being accidentally started.
Place a warning sign on the starting device:
"Machine under repair: do not start."
With electric drive equipment, lock the main switch
open and withdraw any fuses. Put a warning sign on
the fuse box or main switch:
"Machine under repair: do not connect."
Never clean equipment with flammable solvents or
carbon tetrachloride. Protect yourself against toxic
fumes when using cleaning agents.
Refer to the parts list shown in section 8 for item
number references used throughout this section.
6.1 Maintenance schedule
It is recommended that a maintenance plan and
schedule be implemented, in accordance with these
User Instructions, to include the following:
a)
Any auxiliary systems installed must be monitored,
if necessary, to ensure they function correctly.
b) Check for any leaks from gaskets and oil seals.
c) Check bearing lubricant level, and the remaining
hours before a lubricant change is required.
d) Check that the duty condition is in the safe
operating range for the pump.
e) Check vibration, noise level and surface
temperature at the bearings to confirm
satisfactory operation.
f) Check dirt and dust is removed from areas
around close clearances, bearing housings and
motors.
g) Check coupling alignment and re-align if
necessary.
6.1.1
Preventive maintenance
The following sections of this manual give instructions
on how to perform a complete maintenance overhaul.
However, it is also important to periodically repeat the
Pre start-up checks listed in section 5.1. These
checks will help extend pump life as well as the length
of time between major overhauls.
6.1.2
Need for maintenance records
A procedure for keeping accurate maintenance
records is a critical part of any program to improve
pump reliability. There are many variables that can
contribute to pump failures. Often long term and
repetitive problems can only be solved by analyzing
these variables through pump maintenance records.
6.1.3
Cleanliness
One of the major causes of pump failure is the
presence of contaminants in the bearing housing.
This contamination can be in the form of moisture,
dust, dirt and other solid particles such as metal
chips. It is very important that proper cleanliness be
maintained. Some guidelines are listed below.

After draining the oil from the bearing housing,
periodically send it out for analysis. If it is
contaminated, determine the cause and correct.

The work area should be clean and free from
dust, dirt, oil, grease etc.

Hands and gloves should be clean.

Only clean towels, rags and tools should be used.
