approval authorities must be observed and complied
with. The test certificate supplied must be kept close
to the location of operation for easy access
(e.g.foreman’s office).

Commissioning,start-up / shutdown

Commissioning

Caution

: Before starting up the pump make sure

that
- the pump unit has been properly connected to the

electric power supply and is equipped with all
protection devices;

- the pump has been primed with the liquid to be

pumped;

- the direction of rotation has been checked;
- all auxiliary connections have been properly

connected

Final check

It must be easy to rotate the shaft by hand.
Check the integrity and proper functioning of all

connections.

Start-up

Always make sure that the shut-off valve in the
discharge line is closed before the pump is started
up! Only after the pump has reached full rotational
speed shall the shut-off valve in the discharge line be
opened slowly and adjusted to comply with the duty
point.

Caution

: After the operating temperature has been

reached and/or in the event of leakage, switch off
the unit and retighten hex.nuts.

Shutdown

Close the shut-off valve in the discharge line.
If the discharge line is equipped with a non-return or
check valve, the shut-off element may remain open if
there is back pressure.

The shut-off valve in the suction line must not be

closed when switching off the pump.
Switch off the motor, making sure that the unit runs
down smoothly to a standstill.
Depending on the type of installation, the pump
should have a sufficient after-run time – with the heat
source shut off – until the medium handled has
cooled down sufficiently to avoid aheat build-up in
the pump.
For prolonged shutdown, close the shut-off valve in
the suction line. Close the auxiliary connections.
In the event of frost and/or prolonged shutdowns, the
pumpmust be drained or otherwise protected against
freezing.

Servicing / maintenance

General instructions

The operator is responsible for ensuring that all
maintenance, inspection and installation work be
performed by authorized, qualified specialist
personnel who are thoroughly familiar with the
manual.
A regular maintenance schedule will help avoid
expensive repairs and contribute to trouble-free,
reliable operation of the pump with a minimum of
maintenance expenditure and work.

Work on the unit must only be carried out with
the electrical connections disconnected. Make

sure that the pump set cannot be switched on
accidentally (danger to life!).

Pumps handling liquids posing health hazards

must be decontaminated. When draining the
medium see to it that there is no risk to persons or
the environment. All relevant laws must be adhered
to (danger to life!).

Servicing / inspection
Supervision of operation

Caution

: The pump must run quietly and free

from vibrations at all times.
The pump must never be allowed to run dry.

Do not run the pump against a closed shut-off

valve for prolonged periods of time so as to avoid
heating up of the fluid pumped.
Max.permissible room temperature 40 ºC.
Bearing temperature may exceed room
temperature by up to 50 ºC but must never rise
above +90 ºC (measured externally on the motor
housing).

During pump operation the shut-off valve in the

suction line must not be closed.
The mechanical seal shows only slight or invisible
(vapour) leakage during operation.It is
maintenance-free.
Any stand-by pumps installed shall be switched on
and then immediately off again once a week to
keep them operational.
Attention shall be paid to the correct functioning of
the auxiliary connections.

Lubrication and lubricant change
Lubrication

The rolling element bearings in the IEC motor are
grease-lubricated.The lubricant change intervals as
well as the required quantity and quality are
specified below.
