7. Operation
7.1. General
➔
Operate the pump only under the operating parameters and
conditions described in Chapter 4. Technical data.
➔
Make sure the pump is used properly (see Chapter 2.1).
➔
Avoid improper use of the pump (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 machinery or equipment in which they
are installed meet the relevant regulations.
WARNING
Excessive pressure may cause the pump head to
burst.
➔
Do not exceed the maximum permissible operat-
ing pressure (see Chapter 4).
➔
Monitor pressure during operation.
➔
If pressure exceeds the maximum permissible
operating pressure, immediately switch off the
pump and eliminate the fault (see Chapter 9.
Troubleshooting).
➔
Only throttle or regulate the air or gas in the
suction line to prevent the maximum permissible
operating pressure from being exceeded.
➔
If the air or gas quantity is throttled or regulated
in the pressure line, make sure that the maxi-
mum permissible operating pressure is not ex-
ceeded.
➔
Make sure that the pump outlet is not closed or
constricted.
Excessive pressure 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.
➔
When the pump stops, restore the system to normal atmos-
pheric pressure (release pneumatic pressure in pump).
For pumps with AC motor:
Do not allow the pumps to start against pressure or vacuum. If
you experience a brief power interruption, check for the pres-
ence of pressure or vacuum before restarting. If a pump starts
against pressure or vacuum, it may block. This activates the
overload switch and the pump switches off.
➔
Make sure that there is no pressure in the hoses before switch-
ing on the pump.
