7. Operation
Operate the pumps only under the operating parameters and
conditions described in Chapter 4, Technical data.
Make sure that the pumps are being used properly (see Chap-
ter 2.1).
Avoid improper use of the pumps (see Chapter 2.2).
Observe the safety precautions (see Chapter 3).
The pumps are components that are intended to be incorpo-
rated into another machine. Before putting them into service it
must be established that the machinery or systems in which
they are installed meet the relevant regulations.
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 pressure and the inherent dangers thereof can be
prevented by placing a bypass line with a pressure relief valve
between the pressure and suction side of the pump. For further
information, contact your KNF technical adviser (for telephone
number, see last page).
CAUTION
Risk of burns when transferring hot media
Do not touch the pump or the media transfer
system.
Avoid contact with flammable materials.
If the pump stops running, restore the system to normal at-
mospheric pressure.
For pumps with thermal switch or electronic overload protection:
Pump standstill
