6.3 Working substances and auxiliary
agents
Motor lubricants
The specific type of oil used in the motor is given in
Chapter 12.2 "Data sheet". Do not use other oils.
The motor does not require periodic changing of
oil. However, it may be necessary to fill up oil in
larger intervals.
Pump bowl assembly lubricants
NOTE Not all components or sub-
assemblies of a pumping unit are
necessarily supplied by Flowserve
or part of this delivery.
These user instructions apply only
to the components or sub-
assemblies supplied by Flowserve
in this delivery, see Chapter 12.1
"Scope of delivery".
The pump bowl assembly does not contain lubri-
cants.
The bearings of the pump bowl assembly are self-
lubricated by the liquid being pumped.
6.4 Motor maintenance
Motor maintenance can consist of anything from
disassembly and inspection to complete rewinding
and overhaul. In normal service, motor mainte-
nance should be required infrequently.
To determine when motor maintenance is needed,
periodic testing should be faithfully performed as
described in Chapter 6.7 "Periodic testing ", Page
52. If periodic testing is performed satisfactorily,
the need for motor maintenance can usually be
anticipated and maintenance scheduled accord-
ingly.
When periodic testing indicates a motor problem,
remove the pump and inspect the motor while still
vertical in the top of the well to check its electrical
condition (see Chapter 6.8 "Electrical tests", Page
53). Also rotate the shaft manually to check for
possible binding. Spare motors should be main-
tained in field stock to permit rapid re-installation
when a pump is pulled.
No attempt should be made to repair a motor in the
field. If a motor problem is suspected, contact a
Flowserve service representative for further in-
structions. When repair of a motor is required, in-
stall a spare motor in its place and arrange to have
the pumping unit returned to the factory.
6.5 Pump maintenance
NOTE Not all components or sub-
assemblies of a pumping unit are
necessarily supplied by Flowserve
or part of this delivery.
These user instructions apply only
to the components or sub-
assemblies supplied by Flowserve
in this delivery, see Chapter 12.1
"Scope of delivery".
The pumping unit can be operated without mainte-
nance measures, insofar as no irregularities in op-
eration or pumping, caused by sand or a corrosive
pumping medium, make premature removal nec-
essary.
Fluctuating and/or rapidly increasing current con-
sumption points to mechanical problems in the
pump bowl assembly or motor.
Strong oscillation of the pressure and at the same
time of the ammeter can be caused by irregular
water inflow.
6.6 Pump test run
NOTE Not all components or sub-
assemblies of a pumping unit are
necessarily supplied by Flowserve
or part of this delivery.
These user instructions apply only
to the components or sub-
assemblies supplied by Flowserve
in this delivery, see Chapter 12.1
"Scope of delivery".
If the pump bowl assembly should stand idle for a
longer period of time, perform a 10-minute test run
every 2 to 3 months, in order to recognize malfunc-
tions.
CAUTION The pumping unit must be com-
pletely submersed in pumping me-
dium for this test run.
