9.2.1.1 Oil change intervals
The bearing bracket is delivered without the first oil load. Before
start up proceed with oil filling through the filling port “A” (fitted
with a plug/level gauge) up to the indicated oil level.
A = Filling plug
B = Drain plug
C = Constant level oiler
A constant level oiler is available as an option. When oil level
decreases in the bearing housing, air comes in the auxiliary oil tank
and allows oil to go inside the bearing housing. Oil will run in the bearing
housing until optimum level “N” is reached inside.
In this case, first filling of bearing housing is done through the upper
port fitted with a plug.
Level is reached when oil appears in the elbow of the fitting (G). (to
check, rotate tank). Then fill in the auxiliary oil tank and put back in its
vertical position. Always check that oil tank is filled with oil while the
pump is running.
D = Oil tank
E = Fitting
F = Oil tank filling port
G = Elbow of tank fitting.
When assembling the oil tank on the pump, make sure it is
perfectly vertical (pump is horizontal).
Oil change intervals :
If ball bearings are new, oil load should be replaced after 200 hour of
running time, the renewal is as indicated below.
Light duty, bearing temperature below 5°C, no risk of pollution : once a
year.
Standard duty or heavy duty, bearing temperature above 50°C, or
pollution risk : every 6 months.
9.2.1.2 Grease change intervals
Ball bearings are greased before delivery.
Grease change intervals
Light duty conditions
n<1500 RPM
Standard or heavy duty
conditions
1500<n<3000 RPM
Every
5000 hours
Every
2500 hours
Or each 12 months
After 10000 operating hours or after 2 years, bearings should be
dismantled, cleaned and filled again with grease. For unfavorable
operating conditions (severely damp, dusty atmosphere or hot service)
greasing intervals may be shortened.
For grease replacement or re ‐ lubrication, high quality lithium soap
grease should be used (eg. Mobilux 2, Esso Unirex N3, …).
9.3 DISMANTLING AND RE ‐ ASSEMBLY
9.3.1 DISMANTLING
Make sure that electric power is disconnected and could
not be switched on again by fault during maintenance
operations.
• Drain the piping at least between the isolating valve on suction
and discharge sides.
• If necessary disconnect any measuring sensors and gauges.
• Remove drain plug and drain the pump casing.
• If necessary, remove connections to mechanical seal auxiliary
piping.
• If necessary drain oil from bearing bracket and remove constant
level oiler to avoid damages during following operations.
• Pump casing can be kept fastened to pipe work.
• Remove motor fastening screws and move the motor rearward so
that there is enough space to remove the back pull ‐ out assembly.
When using a coupling with spacer part, it is not necessary
to move the motor rearward.
• Dismantle coupling guard, half coupling on pump side.
