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 Section
2.1).
➔ Improper use of the pumps must be prevented (see Section
2.2).
➔ Observe the safety notes (see Chapter 3).
➔ Pumps are components intended to be incorporated into
another machine. The machine/equipment in which the pumps
are installed must be made to fully comply with the pertinent
regulations before being put into operation.
Risk of burning
The drive heats up.
➔ Avoid contact with the drive.
CAUTION ➔ Avoid contact with flammable materials.
Excessive pressures and its inherent dangers 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 adviser
(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:
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
WARNING
restart automatically as soon as they have had time
to cool down.
➔ Take steps to ensure that this cannot produce a
hazardous situation.
Switching the pumps on and off
The motor speed of the pump, and thus the flow rate, is adjustable
and can also be regulated to some extent.
For more details, see Chapter 4, Technical data.
