Installation, Operating and Maintenance Instruction
6.4.2 Abrasive Media
On pumping liquids with abrasive components
an increased wear at hydraulic and shaft sealing
must be expected. The intervals of inspection
should be reduced compared to the usual
times.
6.4.3 Permitted number of starts
The permitted number of starts of the pump must not
be exceeded, see diagram 6.

With electric motors, the permitted number of starts is
given in the attached motor operating instructions.
If two different figures are given, the lower figure is
valid.

6.5 Lubrication

The pump has no bearings and, therefore there´s no
need for lubrication.
For possibly required lubrication of the motor bearings
refer to the Operation and Maintenance Instructions of
the motor supplier.

6.6 Monitoring

Regular monitoring and maintenance will extend
the life of your pump or pump system.
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

Close the valve in discharge pipe right before
(max. 10 seconds) switching off the motor. This is
not necessary if there is a spring-loaded check
valve.
Switch off motor (make sure it runs down quietly).
Close the valve on suction side.
On danger of freezing empty pump and pipes
completely.
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:
Store pump at a dry place.
Rotate pump by hand at least once a month.
6.8.2 Measures for longer putting out of operation
1000
Pump remains installed and in ready for operation:
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
Start-up must be handled like initial start-up (see
chapter 6).
a) Filled pumps
Switch stand-by pumps on and immediately off
again once a week. Possibly use as main pump.
If the stand-by pump is under pressure and
temperature: leave all existing sealing and flushing
systems switched on.
Replace motor bearings after 5 years.
b) Drained pumps
Turn shaft at least 1x week (do not switch on
because of dry running).
Replace motor bearings after 5 years.
Work should only be carried out on the pump or
pump unit when it is not in operation. You must
observe chapter 2.

7.2 Mechanical seals

Before opening the pump, it is essential that you
note chapter 2 and chapter 8.
