7. Operation
The pumps should only be used under the operating
parameters/conditions described in Chapter 4, Technical data.
Ensure that the pumps are being used correctly (see Chapter
2.1).
Improper use of the pumps must be prevented (see Chapter
2.2).
Observe the safety notes (see Chapter 3).
Pumps are components intended to be incorporated into
another machine. Ensure that the machinery/equipment in
which the pumps are installed complies with the pertinent
regulations before putting them into service.
CAUTION
Risk of burning
The drive heats up.
Avoid contact with the pump drive.
Avoid contact with flammable materials.
WARNING
Danger of bursting of the fluid system due to
overpressure.
The pump builds up pressure. A closed system can
cause the max. permitted operating pressure to be
exceeded. This can cause injuries or damage to the
pump and the system.
Avoid operation against a closed system.
Only use wetted parts that are rated for at least
the operating pressure of the pump.
If necessary, limit the maximum system pressure
by suitable measures.
Excessive pressures and the dangers thus caused can be
prevented by using a bypass system with a pressure relief
valve between the pressure and suction side of the pump.
Further information is available from your KNF specialist
(Telephone number: see first page).
If the pump stops running, reduce the pressure in the system
until it is at normal atmospheric pressure.
For pumps with thermal switch or electronic overload protection:
WARNING
Risk of physical injury and damage to the pump due
to automatic start
If the pump overheats and the thermal switch /
electronics stops pump operation, the pumps will
restart automatically as soon as they have had time
to cool down.
Take steps to ensure that this cannot produce a
hazardous situation.
