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.
