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 5.4, Direction of rotation

before connecting the motor to the electrical supply.

4.8

Final shaft alignment check

After connecting piping to the pump, rotate the shaft
several times by hand to ensure there is no binding and
all parts are free. Recheck the coupling alignment, as
previously described, to ensure no pipe strain. If pipe
strain exists, correct piping.

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. The IPS Beacon with a local
display is fitted as standard. When a centralized
control system is required it will be necessary to
replace the IPS Beacon with appropriate temperature
and/or vibration probes.

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,
e.g. grease, oil.

For oil lubricated pumps, fill the bearing

housing [3200] with correct grade of oil to the correct
level, i.e. by use of the sight glass [3856] or

constant

level oiler bottle [3855].

When fitted with a constant level oiler [3855], the bearing
housing [3200] should be filled by unscrewing or hinging
back the transparent bottle and filling it with oil. The
standard Adams oilers and the Trico Watchdog oilers are
self-setting and internally vent balanced.
