A device to provide emergency stopping must
be fitted.
If not supplied pre-wired to the pump unit, the
controller/starter electrical details will also be supplied
within the controller/starter.
For electrical details on pump sets with controllers
see the separate wiring diagram.
See section 5.4, Direction of rotation
before connecting the motor to the electrical supply.
4.9 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 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 is 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 etc.
For oil lubricated pumps, fill the
bearing housing with correct grade of oil to the
correct level, ie sight glass [3856] or
constant level
oiler bottle [3855].
When fitted with a constant level oiler, the bearing
housing should be filled by unscrewing or hinging back
the transparent bottle and filling it with oil. Where an
adjustable body Denco oiler is fitted this should be set to
the height shown in the following diagram:
The oil filled bottle should then be refitted so as to
return it to the upright position. Filling should be
repeated until oil remains visible within the bottle.
Approximate oil volumes are shown in section 5.2.2,
Bearing sizes and capacities.
Grease lubricated pumps and electric motors are
supplied pre-greased.
Where the ambient temperature is very low special
lubricants are required. Where oil lubrication is
utilized and the ambient is less than -5 °C (23 °F)
ensure the oil’s pour point is at least 15 °C (27 ° F)
below the ambient temperature or use oil class SAE
5W-50 or API-SJ and ensure the upper operating
range of the oil is then not exceeded.
Other drivers and gearboxes, if appropriate, should
be lubricated in accordance with their manuals.
