most the middle of the oil level sight glass in the
main body.
ƒ Using a funnel, fill the reservoir (picture 8).
ƒ Make sure that o-ring is on reservoir spout.
ƒ Place thumb over reservoir spout, invert, and
insert the spout into the internal threaded boss on
the main body. Tighten reservoir (picture 8).
ƒ Now the oil is flowing from the reservoir into the
bearing chamber.
ƒ Repeat filling till the reservoir stays full to 2/3 rd
.
ƒ Refill oil as soon as the oil level falls below 1/3 rd
.

6.5.2 Grease lubrication
For quality of grease refer to chapter 7.4.2.
For quantity of grease refer to chapter 7.4.2.
ƒ The bearings are already filled with lithium based
grease at the factory and are thus ready for use.
ƒ The grease provided is suitable for a temperature
range from -30° to +90°C (measured at surface of
bearing bracket).
ƒ Re-lubrication via the two grease nipples (636).
ƒ Bearing temperature (measured at bearing
bracket) should lie max. 50°C over ambient tem-
perature and must not exceed 90°C, control
weekly at least. On grease lubrication the bearing
temperature can temporarily be higher by 5-10°C
after regreasing, till a possible surplus of grease
in the bearings is cut.
6.6 Monitoring
In areas endangered to explosion it is recom-
mended to monitor the temperature of the bear-
ings and the vibrations of the bearing bracket.
Regular monitoring and maintenance will ex-
tend the life of your pump or pump system.
ƒ Check oil level at least once a week and top up if
necessary.
ƒ Check pump for leaks at least once a week.
ƒ On packing, check quantity of leakage at least
once a week (see chapter 6.2 section "Packing").
ƒ Check the regulating and monitoring devices of
any sealing, flushing or cooling systems once a
week to ensure that they function properly. Outgo-
ing cooling water should be handwarm.
ƒ With double mechanical seals, monitor pressure
and flow rate in mechanical seal area; check at
least once a week.
ƒ Pumps which are exposed to corrosive chemicals
or to wear through abrasion must be inspected
periodically for corrosion or wear and tear. The
first inspection should be carried out after six
months. All further inspection intervals should be
determined on the basis of the state of the pump.
6.7 Shutting down
ƒ Close the valve in discharge pipe right before
(max. 30 seconds) switching off the motor. This is
not necessary if there is a spring-loaded check
valve.
ƒ Switch off motor (make sure it runs down quietly).
ƒ Close the valve on suction side.
ƒ Close auxiliary systems. Do not shut down cooling
system until pump has cooled down.
ƒ If there is any risk of freezing, empty pump, cool-
ing areas and pipes completely.
ƒ If the pump also remains under operating condi-
tions (pressure and temperature) when station-
ary,leave all sealing, flushing and cooling systems
switched on.
ƒ The shaft sealing must remain sealed if there is a
risk of air being sucked in (in the event of supply
from vacuum systems or parallel operation with
shared suction pipe).
6.8 Storage / longer periods of non-
operation
6.8.1 Storage of new pumps
If the putting into operation shall happen a longer
period after the delivery, we recommend the following
measures for the storage of the pump:
ƒ Store pump at a dry place.
ƒ Rotate pump by hand at least once a month.
6.8.2 Measures for longer putting out of operation
Pump remains installed and in ready for operation:
ƒ Test runs of 5 min. duration must be made in
regular intervals. The span between the test runs
is depending on the plant. However, it should be
made once a week, at least.
6.8.3 Longer periods of non-operation
After long stationary periods, packings may
have hardened; these must be replaced before
start-up.
When starting up, follow the instructions for
starting up for the first time (see chapter 6)!
a) Filled pumps
ƒ Switch stand-by pumps on and immediately off
again once a week. Possibly use as main pump.
ƒ If the stand-by pump is at operating pressure and
temperature, leave all sealing, flushing and cool-
ing systems switched on.
ƒ Replace oil or grease after 2 years.
ƒ Stuffing box must be adjusted to maintain lubrica-
tion of the packing (e.g. do not over tighten).
