Installation, Operating and Maintenance Instruction
The coupling guard (5) is clamped by fastening the
two lower screws on the pumpside coupling disc (6)
and the motorside coupling ring (7).

5.4 Drive

On selecting the motor size care has to be taken, that
the requirements acc. to ISO 5199 are fulfilled. Note
the
Operating
Instructions
manufacturer.

6. Start-up, Operation, Shut down

The plant may only be started up by people who
are familiar with the local safety regulations and
with these Operating Instructions (especially
with
the
safety
instructions given here).

6.1 Initial start-up

Before starting up the pump, check, if the following
points were controlled and carried out:
Pump and suction pipe must be filled completely
with liquid when starting up.
Turn pump unit once again by hand and check
that it moves smoothly and evenly.
Check that coupling guard is installed and that all
safety devices are operational.
Open valve in suction /intake pipe.
Set discharge side valve to approx. 25% of rated
flow quantity. With pumps with a discharge branch
rated width less than 200, the valve can remain
closed when starting up.
Secure, that unit is electrically connected acc. to
all regulations and with all safety devices.
Check direction of rotation by switching on and off
briefly. It must be the same as the directional
arrow on the bearing frame.

6.2 Switch on drive

Immediately (max. 30 seconds on 50 Hz resp.
max. 20 seconds on 60 Hz currency feed) after

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.
Care must be taken that the base frame (2x
M10-thread available for earthing screws) is
earthed by means of corresponding measures.
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.
reaching normal operating speed open discharge
valve adjust the required operating point. The
pumping data shown at the type plate resp. in the
data sheet and / or the order confirmation must be
met. Every change is only permitted after talking
with the manufacturer!
In order that the shaft sealing can be monitored
and maintained unhindered, no protection cover
is provided in this area. Therefore special
attention is required when pump is working (no
long hair, loose clothes, a.s.o.).
Operation with closed valve in the suction and /
or discharge piping is not permitted.
On starting-up without back-pressure, the back-
pressure must be produced through throttling at
the discharge side. After reaching full back-
pressure open valve.
If pump does not reach attended head or if
atypical sounds or vibrations do occur:
Switch off pump (see chapter 6.7) and seek for
causes (see chapter 10).

6.3 Restarting

Basically, the same procedure should be followed as
for starting up for the first time. However, there is no
need to check the direction of rotation and the
accessibility of the pump unit.
