4.7 Protection systems
The following protection systems are
recommended particularly if the pump is installed in a 
potentially explosive area or is handling a hazardous 
liquid. If in any doubt consult Flowserve. 
If there is any possibility of the system allowing the 
pump to run against a closed valve or below 
minimum continuous safe flow a protection device 
should be installed to ensure the temperature of the 
liquid does not rise to an unsafe level. 
If there are any circumstances in which the system 
can allow the pump to run dry, or start up empty, a 
power monitor should, in addition to level control, be 
fitted to stop the pump or prevent it from being 
started. This is particularly relevant if the pump is 
handling a flammable liquid. 
If leakage of product from the pump or its associated 
sealing system can cause a hazard it is recommended 
that an appropriate leakage detection system is installed. 
To prevent excessive surface temperatures at 
bearings it is recommended that temperature or 
vibration monitoring are carried out. 
5 COMMISSIONING, START-UP, 
OPERATION AND SHUTDOWN 
These operations must be carried
out by fully qualified personnel.
5.1 Pre-commissioning procedure
5.1.1 Lubrication 
Determine the mode of lubrication of the pump set, 
eg grease, oil, product lubrication, external clean 
liquid etc. 
For oil lubricated pumps, fill the bearing
housing with correct grade of oil to the correct level.

Trico oiler option
Pumps with grease lubricated antifriction bearings are 
normally supplied fitted with grease nipples and with 
pre-greased bearings. 
 
Grease lubricated electric motor bearings are generally 
pre-greased. Refer to the motor UI for information on 
the motor lubrication schedule. 
 
Pumps with grease lubricated thrust bearings and 
electric motors are supplied with pre-greased bearings. 
In the case of product lubricated bearings
the source of product supply should be checked against 
the order; there may be requirements for an external clean 
supply, particular supply pressure or the commencement 
of lubrication supply before pump start-up. 
 
Approximate oil volumes are shown in section 5.2.2, 
Bearing sizes and capacities. 
Where the ambient is very low special lubricants are 
required. If in doubt consult Flowserve for 
recommendations of oil and grease types at these 
lower temperatures. Where oil lubrication is utilized 
and the ambient is less than -5 °C (23 °F) ensure t he 
ambient is no lower than 15 °C (27 °F) over the oil 
pour point or use the oil class SAE 5W-50 or API-SJ 
and ensure the upper operating range of the oil is 
then not exceeded. Where low ambient grease has 
been specially fitted this is Shell Aeroshell 22.
