Operation

➔ The pumps should only be used under the operating parame-
ters/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 prevent-
ed 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 / elec-
tronics stops pump operation, the pumps will restart
WARNING
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 pumps, and thus the flow rate, is adjusta-
ble and can also be regulated to some extent.
For more details, see Chapter 4, Technical data.
Duty cycle / impulse operation
KNF pumps are designed for continuous operation.
Short start and stop cycles may adversely affect the service life of
the brushed motors.
