Installation, Operating and Maintenance Instruction
If the liquid being handled leaks out at the mechanical
seal, it is damaged and must be replaced.

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.

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.

9. Spare parts, Spare pumps

9.1 Spare parts

Spare parts should be selected to last for two-years
continuous operation. If no other guidelines are
applicable, we recommend that you stock the number
of parts listed below (in accordance with VDMA
24296).
To ensure optimum availability, we recommend
that suitable quantities of spare parts are held in
stock, especially if these are made from special
materials and in the case of mechanical seals,
because of the longer delivery times.

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.
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 (blow lamp, 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

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.
