4.2.3 Oil
emperature
Oil temperature should be maintained between 16
o
C (60
o
F) and 82
o
C (180
o
F).
Caution
The minimum bearing oil temperature is 16
o
C (60
o
F). If necessary, prior to startup,
one of the following procedures should be employed:
a)
Drain the oil in the bearing housing(s) and replace with warm oil.
b)
Heat the bearing housing(s) using heat tape (or other suitable means).
c)
Circulate warm liquid through the cooling jacket or immersion cooler (if
supplied).
d)
Utilize oil with a lower viscosity, or VG number, or consider using a
synthetics hydrocarbon oil with a low pour point to give a viscosity similar
to that of ISO 46 (for maximum oil operating temperatures of 180°F) or
ISO 32 (for maximum oil operating temperatures of 120°F).
NOTE
ISO 46 is recommended for continuous operating oil temperatures between 38°C
(100°F) and 82 °C (180°F), with a minimum startup temperature of 16°C (60°F);
ISO 32 may be considered for continuous operating oil temperatures between 16°C
(60°F) and 49 °C (120 °F), with a minimum start up temperature of 4°C (40°F). For
startup when oil temperature is below 4°C (40°F), oil preheating is recommended.
4.2.4 Cleaning the lubrication system prior to operation
Before operating the pump, the lubrication system should be thoroughly cleaned to remove any foreign matter
that may have accumulated during shipment, storage or installation. To clean the lubrication system refer to the
Sectional drawing and proceeds as follows
:
a)
Remove the bearing caps, bearing linings, thrust shoes and drain plugs.
b)
Flush out the bearing housings with kerosene or other suitable solvent.
c)
Wash the bearing linings and thrust shoes with a suitable solvent.
d)
Flush the entire lubrication system with oil. Flushing oil should be compatible with lubricating.
e)
During flushing operation, examine the piping for leaks and correct as necessary
f)
After flushing, replace drain plugs. Reassemble bearings and torque end cover bolting
g)
Refer to driver instruction book for instructions covering flushing of driver bearings.
4.3 Direction of rotation
Caution
Check pump rotating
4.4 Guarding
WARNING
-
Guarding is supplied and fitted to the pump set.
-
Fasteners must remain captive in the guard when the guard is removed to
comply with Machinery Directive 2006/42/EC.
