2. Use
2.1. Intended use
The pumps are intended for transferring and metering liquids.
Owner's responsibility
Only install and operate the pumps under the operating parameters
and conditions described in Chapter 4, Technical data, and Section
2.3, Using the pump in a potentially explosive atmosphere.
Only complete pumps may be taken into service.
Before transferring or metering a medium, check whether the
medium can be transferred danger-free in the specific application
case.
Before using a medium, check the compatibility of the materials of
the pump head, pump housing, diaphragm and valves with the
medium.
The temperature of the medium must lie within the permissible
temperature range (see Chapter 4).
The transferred medium should not contain particles as these can
prevent the pump from working correctly. If this cannot be guaran-
teed, a filter < 100

m with sufficiently large filter area must be
used upstream of the pump.
2.2. Improper use
For special modifications outside the standard technical specifica-
tions, please contact your KNF technical adviser.
2.3. Using the pump in a potentially explosive
atmosphere
Only pumps of the appropriate Equipment Category and tempera-
ture class must be operated in potentially explosive atmospheres
(areas).
Such pumps have the following explosion prevention and protec-
tion markings:
