bearings, worn couplings, vibration and possible
failure of the pump casing. The following points
should be strictly followed:

Prevent excessive external pipe load

Never draw piping into place by applying force
to pump flange connections

Do not mount expansion joints so that their
force, due to internal pressure, acts on the pipe
flange
Contact your local Flowserve Sales office,
Distributor, or Representative for further details.
4.5.5 Auxiliary piping
The connections that are to be
piped up will have been fitted with protective metal
or plastic plugs which will need to be removed.
4.5.5.1 Pumps fitted with heating/cooling
jackets
Connect the heating/cooling pipes from the site
supply. The top connection should be used as the
outlet to ensure complete filling/venting of the
annulus with heating/cooling liquids. Inlet for steam
is usually at the top, outlet at the bottom.
4.6 Electrical connections
Electrical connections must be made
by a qualified Electrician in accordance with
relevant local national and international regulations.
It is important to be aware of the EUROPEAN
DIRECTIVE on potentially explosive areas where
compliance with IEC60079-14 is an additional
requirement for making electrical connections.
It is important to be aware of the EUROPEAN
DIRECTIVE on electromagnetic 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.
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.
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 5.2, Direction of
rotation before connecting the motor to the
electrical supply.
For close coupled pumps it is
necessary to wire the motor with flexible conduit of
sufficient length to allow the motor/power end
assembly to be moved back from the casing [1100]
for maintenance.
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 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 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.
