If required, temperature of the liquid in the drive
and the metal shell (when single containment) can
also be monitored from the tapping points shown.
As each system has its unique requirements it is
recommended that Flowserve is consulted when
advice is required.

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 etc.
For oil lubricated pumps, fill the
bearing housing with correct grade of oil to the
correct level, ie oil sight guage [3856] or
constant
level oiler bottle [3855].
Where an adjustable body Denco oiler is fitted this
should be set to the height shown in the following
diagram:
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.
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.
Oil lubricated units are supplied
without oil and must be filled to the marked level
before starting the pump.
To fill the bearing housing with oil, unscrew the oil
filler/breather and fill through the orifice.
Approximate oil volumes are shown in section
5.2.2, Bearing sizes and capacities.
Grease lubricated pumps and electric motors are
supplied pre-greased.
Other drivers and gearboxes, if appropriate, should
be lubricated in accordance with their manuals.
Where the ambient is very low special lubricants
are required. Refer to Flowserve when outside the
lubricant temperature range -5 to 82 ºC
(23 to 179 ºF). Where oil lubrication is utilized and
the ambient is less than -5 °C (23 °F) ensure the o il
pour point is at least 15 °C (27 °F) lower than the
ambient or use oil class SAE 5W-50 or API-SJ and
ensure the upper operating range of the oil is then
not exceeded. IS0 VG 46 oil is generally selected
for an initial lubrication schedule.
