5 COMMISSIONING, START-UP,
OPERATION AND SHUTDOWN
Fully qualified personnel must
carry out these operations.
5.1 Pre-commissioning procedure
5.1.1 Lubrication
Determine the mode of lubrication of the pump set,
e.g. grease, product lubrication etc.
Grease lubricated pumps and electric motors are
supplied pre-greased. Other drivers and gearboxes, if
appropriate, should be lubricated in accordance with
their manuals.
In the case of product lubricated
bearings the source of product supply should be
checked against the order. The bearings below the
top plate are water lubricated. These will require
external clean supply. Commencement of lubrication
supply is required before pump start-up.
5.2 Bearing lubricants
5.2.1 Recommended grease lubricants
* NLGI 2 is an alternative grease and is not to be mixed with other
grades
** Factory packed bearings for the temperature range with grease
nipples
5.2.1.1 Recommended fill quantities
Refer to section 3.4.2, Pump and impeller data.
5.2.1.2 Lubrication schedule
When grease nipples are fitted, one charge between
grease changes is advisable for most operating
conditions, i.e. 1 000 hours interval.
Normal intervals between grease changes are 4 000
hours or at least every 6 months.
The characteristics of the installation and severity of
service will determine the frequency of lubrication.
Lubricant and bearing temperature analysis can be
useful in optimising lubricant change intervals.
The bearing temperature may be allowed to rise to
55 ºC (131 ºF) above ambient but should not exceed
95
°C (204 °F). For most operating conditions quality
grease having a lithium soap base and NLGI
consistency of No 2 or No 3 is recommended. The
drop point should exceed 175 ºC (350 ºF).
Never mix greases containing different
bases, thickeners or additives.
5.2.2 Water Lubricated Bearings
Bearings must be thoroughly wetted before
operation. In most cases the lower bearing will be
submerged but it is essential that a flush of clean
liquid be supplied.
5.2.2.1
Water Supply Pressure - 30-40 psig
5.2.2.2 Temperature – Supply temperature should not

5.3 Direction of rotation
Ensure the pump is given the same
rotation as the pump direction arrow cast on the
pump casing. Rotation is clockwise when the pump is
viewed from the driver. The impeller may unscrew if
run in reverse rotation.
On shut down, the impeller must be free to rotate. A
racket type motor must not be used.
