2.  Use 

2.1.  Intended use 

The pumps are intended for transferring and metering liquids. 

Owner's responsibility 

Install and operate the pumps only under the operating parameters 
and conditions described in Chapter 4. Technical data. 

Only completely installed 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. 

  Filters may be ordered as accessories, see Spare Parts and 

Accessories (Chapter 10). 

 

2.2.  Improper use 

 

DANGER 

 

The pumps must not be operated in an explosive 
atmosphere. 

 

 

 

Please contact your local KNF partner for special designs that 
are not included in the technical specification (www.knf.com).
