compatibility when wiring up and installing equipment
on site. Attention must be paid to ensure that the
techniques used during wiring/installation do not
increase electromagnetic emissions or decrease the
electromagnetic immunity of the equipment, wiring or
any connected devices. If in any doubt, contact
Flowserve for advice.
4.9.4 The motor must be wired up in
accordance with the motor manufacturer's
instructions (normally supplied within the terminal
box) including any temperature, earth leakage,
current and other protective devices as appropriate.
The identification nameplate should be checked to
ensure the power supply is appropriate.
4.9.5 A device to provide emergency stopping
must be fitted.
4.9.6 If not supplied pre-wired to the pump unit, the
controller/starter electrical details will also be
supplied within the controller/starter.
4.8.7 For electrical details on pump sets with
controllers see the separate wiring diagram.
4.8.8 See section 5.3, Direction of
rotation before connecting the motor to the electrical
supply.
4.10 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 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 are carried out. See sections
5.7.4 and 5.7.5.
5 COMMISSIONING, START-UP,
OPERATION AND SHUTDOWN
These operations must be carried
out by fully qualified personnel.
5.1 Lubrication Methods
Determine the mode of lubrication of the pump set,
eg grease, oil, product lubrication etc.
For oil bath lubricated pumps, fill the
bearing housing with correct grade of oil to the
correct level, ie sight glass or
constant level oiler
bottle.
5.1.1 Oil Bath Lubrication
When fitted with a constant level oiler, the bearing
housing should be filled by unscrewing or hinging
back the transparent bottle and filling the bottle with
oil. Where an adjustable body Trico oiler is fitted this
should be set to the proper height.
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 5.2.3,
Recommended Fill Capacities
.
5.1.2 Grease Lubrication
Grease lubricated pumps and electric motors are
supplied pre-greased.
5.1.3 Oil Mist Lubrication
FRBH pumps may be lubricated by pure or purge oil
mist. See comments below.
5.1.3.1 Purge Mist
In the case of purge mist an oil level is maintained in
the bearing frame. No changes are required to be
made to the pump, however, the oil level must be
maintained at site glass center. Excess oil must be
removed. Oil is injected outboard of each bearing.
