7. Operation
➔
Only operate the pumps under the operating parameters and
conditions described in Chapter 4, Technical data, and in Sec-
tion 2.3, Using the pump in a potentially explosive atmosphere.
➔
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.
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 (Telephone
number: see first page).
WARNING
Risk of explosion as a result of high ambient tem-
perature
➔
Monitor ambient temperature (heat of compres-
sion, motor heat).
➔
Provide an adequate supply of cooling air.
➔
If the pump stops running, restore the system to normal at-
mospheric pressure.
Check the pump regularly for external damage or leaks.
Duty cycle / short cycle operation
KNF pumps are designed for continuous operation.
If the pump is operated with short cycles in your application,
please contact a KNF technical adviser for further information
(Telephone number: see first page).
Switching on the pump
➔
In order to ensure that the pump starts every time, make sure
that counterpressure is reduced to an acceptable level before
start-up. This should also be done during operation after a brief
power cut.
