Installation, Operating and Maintenance Instruction
recommended that a sieve, 800 micron, is
installed in the suction/intake pipe when the motor
is being started up.
If the pipe system is tested with the pump
installed, do not exceed the maximum permitted
casing pressure of the pump and/or shaft sealing
(see data sheet).
When emptying the pipe after the pressure test,
make sure that the pump is treated properly
(danger of rust and problems when starting up).
In the case of pumps with stuffing boxes, replace
packing after pressure test (packing may be over-
compressed and thus no longer suitable for use).
5.2.2 Additional connections
Any required sealing, flushing or cooling pipe
connections must be installed. Please consult the data
sheet to see which pipes, pressures and amounts are
necessary. See the drawings in the enclosures for the
location and size of the connections to the pump.

connections
function!
It is recommended that a pipeline is installed to take
off any leakage from the shaft seal. For connection,
see appendix, "Connections".
5.3 Coupling
Make sure that nobody can start the motor
during work on the coupling.
According to Accident Prevention Regulations,
the pump unit may only be operated when the
coupling guard is mounted.
With pump units (i.e. pump with motor) supplied
complete, no work is required on the coupling before
use.
5.3.1 Coupling – MPB Design
The pump and motor are rigidly connected together,
meaning that no adjustment work is required if the
motor is replaced properly.
5.3.2 Coupling – MPV Design
If the pump unit is not completely assembled until it
reaches its place of use and no separate operating
instructions have been supplied by the manufacturer,
you should proceed according to the following points:
Before starting installation, carefully clean shaft
ends and coupling components.
Pull coupling onto shaft end, do not hit. The
coupling may be heated beforehand in an oil bath
to approx. 100° C (pulling on is then easier).
Remove rubber packs from coupling section first.
Keep the axial distance from both of the coupling
halfs.
The coupling sections must be flush with the shaft
end surfaces.
Mount coupling guard.

are essential for
the
page 83
On operation in zone 1 and 2 a coupling with
valid Atex-certification must be used.
The Operating Instructions of the manufacturer
must be followed.
Aligning of the coupling is not necessary.
5.3.3 Coupling Guard
Acc. to accident prevention regulations the
pump must only be operated with coupling
guard.
Care has to be taken, that the used coupling
guard consists of non-sparking material.
5.4 Drive
On selecting the motor size care has to be taken, that
the requirements acc. to ISO 5199 are fulfilled.
The Operating Instructions of the manufacturer
must be followed.
On application in zone 1 and 2 a motor with
valid Atex-certification must be used.
5.5 Electric Connection
Electrical connection work may only be carried
out by an authorised professional. The rules
and regulations valid for electrical technology,
especially
those
measures, must be observed. The regulations
of
the national power supply companies
operating in that area must also be observed.
Before starting work, check that the information on the
motor name plate is the same as the local mains
network. The power supply cable of the coupled drive
motor must be connected up in accordance with the
wiring diagram produced by the motor manufacturer. A
protective motor switch must be provided.
In areas endangered to explosion IEC 60079-14
must additionally be noticed for the electric
installation.
The direction of rotation must only be checked
when the pump is full. Dry running will cause
damage to the pump.
5.6 Final Control
Check alignment of coupling acc. to chapter 5.3.1
again. It must be possible to turn the unit easily by
hand at the coupling.
