3.4 Principles
Before delivery, the manufacturer inspected the dosing pump and
n
operated it under specific conditions (with a specific dosing medium
with a specific density and temperature, with specific pipe dimen-
sions, etc.) Since these conditions differ at every location of usage,
the delivery capacity of the dosing pump should be measured by
gauging it at the operating company's installation. For details on the
approximate values and the capacity of the dosing pump, refer to the
chapter 15 "Delivery characteristic curves" on page 40.
Comply with the information regarding the operating and environmen-
n
tal conditions (see chapter 5 "Technical data" on page 13).
Any restrictions regarding the viscosity, temperature and density of
n
dosing media must be followed. You must only use dosing media at
temperatures above freezing point or below the boiling point of the
respective medium.
The materials of the dosing pump and hydraulic parts of the system
n
must be suitable for the dosing medium that is used. In this connec-
tion, note that the resistance of these components can change in

dependence on the temperature of the media and the operating
pressure.
Information on the suitability of materials combined with
i
different dosing media can be found in the Compatibility Chart
of Neptune.
The information in this resistance list is based on information
from the material manufacturers and on expertise obtained by
Neptune from handling the materials.
As the durability of the materials depends on many factors,
this list only constitutes initial guidance on selecting material.
In all cases, test the equipment with the chemicals you use
under operating conditions.
The dosing pump is not intended for outdoor use unless appropriate
n
protective measures have been taken.
Avoid leaks of liquids and dust into the casing and avoid direct
n
exposure to sunlight.
You must never operate dosing pumps in a potentially explosive
n
atmosphere if they do not have corresponding nameplates or an
appropriate EU Declaration of Conformity for potentially explosive
atmospheres.
3.5 Prohibited dosing media
The dosing pump must not be used for these media and substances:
Gaseous media,
n
radioactive media,
n
solid substances,
n
combustible media,
n
all other media that are not suitable for delivery using this dosing
n
pump.
3.6 Foreseeable misuse
Below, there is information about the applications of the dosing pump or
associated equipment that are not considered to be intended use. This
section is intended to allow you to detect possible misuse in advance and
to avoid it.
