CAUTION:
When the motor is running but the pump is not conveying, this means that the magnetic drive
has stopped.
7.
Switch the motor off immediately to prevent overheating of the magnets.
Then proceeded as follows:
a) Close discharge valve down to the position
minimum flow rate
.
b) Start motor again.
If the magnetic drive stops again, look for the cause.
6.2 Operating limits
CAUTION:
The operating limits of the pump/unit in terms of pressure, temperature, power and speed
are entered in the data sheet and it is imperative to observe them.
6.2.1 Abrasive media
If liquids with abrasive constituents are conveyed, increased wear at the pump is to be expected.
The inspection intervals should be reduced compared with the usual times.
6.2.2 Min./max. flow rate
The operating range generally recommended lies at 0.3 Q
opt
to 1.1 Q
opt
. Consult the manufacturer for
operation outside this range and observe Special operating conditions.
6.3 Shutdown
1.
Close discharge valve down to the position
minimum flow rate
.
2.
Switch motor off.
3.
Close discharge valve completely.
Only close the suction line if the pump is to be evacuated or dismantled.
For all work on the machine, make sure that the motor cannot be inadvertently switched on.
If the pump is to be evacuated or flushed, observe the local regulations.
CAUTION:
•
It is recommended to wait one hour before the pump is dismantled from the plant to
permit static peak charges to be eliminated.
•
If the pump is returned to the manufacturer's, clean the pump very thoroughly.
6.4 Restarting
When the pump is restarted, it must be ensured that all the relative steps as described in
are repeated, depending on the progress of the shutdown operation.
