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.
Only fully assembled 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 range (see
Chapter 4).
The pumped medium should not contain particles as these can prevent the
pump from working correctly. If this cannot be ensured, a < 50
m filter with a
sufficiently large filter area must be used upstream of the pump.
2.2. Improper use
The pumps must not be operated in a potentially explosive atmosphere.
The maximum ambient temperature must not exceed 40°C.
Do not use the pump controller in a damp environment or under condensing
conditions.
The controller must be protected against contamination, and contact with
liquids, solvents or vapours must be avoided.
The pump controller must only be operated when adapted to meet the ESD
(Electrostatic Discharge) safety standards.
Do not establish uncontrolled connections between the controller and conduc-
tive cables and materials.
For special modifications to the pumps outside the standard technical specifi-
cations please contact a KNF technical adviser.
