7. Servicing, Maintenance
7.1 General remarks
Work should only be carried out on the pump or
pump unit when it is not in operation. You must
observe chapter 2.
Maintenance and servicing work must only be
carried out by trained, experienced staff who
are familiar with the contents of these
Operating Instructions, or by the Manufacturer's
own service staff.
7.2 Mechanical seals
Before opening the pump, it is essential that
you note chapter 2 and chapter 8.
If the liquid being handled leaks out at the mechanical
seal, it is damaged and must be replaced.
Replacement of the mech. seal according to
accompanying "Mounting Instructions for Shaft
sealing".
7.3 Motor bearings
After approx. 5 years the grease in the motor bearings
is so aged, that a replacement of the bearings is
recommended. However, the bearings must be
replaced after 25000 operating hours, at least, resp.
acc. to the Maintenance Instruction of the motor
supplier, if that recommends a shorter maintenance
period.
7.4 Cleaning of pump
Dirt on the outside of the pump has an adverse
effect on transmission of heat. The pump should
therefore be cleaned with water at regular
intervals (depending on the degree of dirt).
The pump must not be cleaned with
pressurised water - water will get into the
bearings.
8. Dismantling and repair of pump
8.1 General remarks
Repair to the pump or pump system may only
be carried out by authorised skilled personnel
or by the manufacturer´s specialist staff.
When disassembling the pump pay attention to
chapter 2 and chapter 4.1.
For mounting and repair you can order specialized
personnel if you want.
If dangerous liquids are pumped the
appropriate disposal of the handled liquid is
necessary before the disassembly of the pump.
Pay attention to the fact, that even in drained
pumps there are remainders of the handled
liquid. If necessary the pump must be flushed
or decontaminated. Laws must be observed,
otherwise danger to health is existing!
Before the disassembly the pump has to be
secured in such a way, that it can´t be started.
The pump casing must be drained and without
pressure.
All locking devices in the suction- and discharge-
pipe must be closed.
All parts must have taken on the temperature of
the environment.
Secure disassembled pumps, units or single
parts against tipping over or rolling off.
While disassembling the pump use of an open
flame (blowlamp, etc.) only, when there is no
danger of setting fire, cause an explosion or
cause injurious vapours.
Use original spare parts only. Pay attention to
the right materials and the matching design.
8.2 General
Works, which require shocks (hammer), must
only be performed outside the explosive
atmosphere or only non-sparking tools must be
used.
Carry out disassembly and mounting according to the
appropriate sectional drawing.
You will only need common tools.
Before disassembly check if required parts are ready.
Disassemble the pump only so far, as required for the
replacement of the repair part.
8.3 Removal and Installation of screen in
the motor lantern
The guard plates (680) are fixed in the windows of the
motor lantern (681).
For removing insert a screwdriver about 4 cm into the
last row with punches of the guard plate. Then pull up
the screwdriver until the lower edge of the guard plate
lifts off the window. Now you can remove the
screwdriver together with the guard plate from the
window (see picture 8).
On installation insert the screwdriver about 4 cm into
the last row with punches of the guard plate. Then put
the upper part of the guard plate into the upper edge
of the window. Now pull up the screw driver until the
