Installation, Operating and Maintenance Instruction
For couplings with rubber pads the following applies:
Unless a clearance in the couplings is necessary, the
coupling pads may wear out to approximately ¼ of
their usual thickness, before they have to be changed.
To measure the clearance in the coupling place a
mark on the O.D. of each coupling hub (see following
pic). Then fixing one hub, turn the opposite hub as far
as possible. Then measure the distance ( ∆ S
between the marks of the coupling. If this measure
exceeds the value given in the chart, the packing must
be replaced. They must be replaced in sets.

If wear is heavy, it must be assumed that the
motor is not properly aligned with the pump or
that the distance between the coupling sections
has changed. Replace worn elements and re-
install or adjust coupling, as described in
chapter 5.3.

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.
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.
Never apply heat to remove the impeller nut.
Use of heat may result in severe physical injury
and property damage.

7.6 Cleaning of pump

The
pressurised water - water will get into the
bearings.
Dirt on the outside of the pump has an adverse effect
)
V
on transmission of heat. The pump should therefore
be cleaned with water at regular intervals (depending
on the degree of dirt).
Secure disassembled pumps, units or single
parts against tipping over or rolling off.
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.
The
schematic
designations that matches the delivered pump and the
design of the shaft seal can be found in the enclosed
data sheet and/or the order confirmation and the
enclosures.
All work carried out on the pump must be performed in
compliance with the rules of machine construction.
Never use force (never hit too hard with a hammer
and always use a suitable base (hard wood or
copper)).
Obey safety instructions, secure components so
that they cannot fall over or roll away
Only use suitable products in a perfect technical
condition, (e.g. properties of lubricating agent
must be known)
Always clean parts before installation (dust, rust,
particles, old grease etc.).
All specified values must be complied with (e.g.
torque etc.)
Fitting surfaces and centering should only be
lubricated shortly before assembly.
