Caution
Never operate the machine if the safety and monitor-
ing devices have been removed or damage, or if they
do not work.

2.8. Pumped fluids

Each pumped fluid differs in regard to composition, cor-
rosiveness, abrasiveness, TS content and many other
aspects. Generally, our products can be used for many
applications. For more precise details, see chapter 3, the
machine data sheet and the order confirmation. It should
be remembered that if the density, viscosity or the gener-
al composition change, this can also alter many parame-
ters of the product.
Different materials and impeller shapes are required for
different pumped fluids. The more exact your specifica-
tions on your order, the more exactly we can modify our
product to meet your requirements. If the area of applica-
tion and/or the pumped fluid change, we will be happy to
offer supportive advice.
When switching the product into another pumped fluid,
observe the following points:
• Products which have been operated in sewage or
waste water must be thoroughly cleaned with pure
water or drinking water before use.
• Products which have pumped fluids which are haz-
ardous to health must always be decontaminated
before changing to a new fluid. Also clarify whether
the product may be used in a different pumped fluid.
• With products which have been operated with a lu-
bricant or cooling fluid (such as oil), this can escape
into the pumped fluid if the mechanical shaft seal is
defective.
Danger - explosive fluids!
It is absolutely prohibited to pump explosive liquids
(e.g. gasoline, kerosene, etc.). The products are not
designed for these liquids!

2.9. Sound Pressure

Depending on the size and power (kW), the pump has
a sound pressure of about 40dB (A) to 70dB (A) during
operation. However, the actual sound pressure depends
on several factors. These are, for example, the type of
installation and set-up, mounting of accessories, piping,
operating point, immersion depth, and much more.

3. General description

3.1. Applications

These pumps are suitable for transferring wastewater,
rainwater or ground water containing solids of up to 10
mm diameter. The H16 pump is suitable for pumping
media with highly abrasive components (e.g. sand, grav-
el, stone). When chemically aggressive constituents are
present in the pumped medium, it is absolutely necessary
to take into account the chemical resistance of the con-
struction materials used.
No operation in "slurping mode" is permitted. The mini-
mum level for the pumped medium must always, depend-
ing on the method of installation, be situated above the
upper edge of the pump housing.
The pumped medium can have a temperature of up to
40°C, and to a maximum of 60°C for short periods. The
maximum density of the pumped medium is 1040 kg/m³
and the pH value can be 6 - 8. However, the pH value in it-
self is only a guide. In every case, the chemical resistance
of the pump must be the subject of a request to the pump
manufacturer, giving the composition of the medium.

3.2. Operating modes

The pumps are designed for operating modes S1 (continu-
ous operation) and S3 (intermittent operation). Please take
the precise data from the table in Chapter 3.3.2 Motor.

3.3. Construction

The fully-submersible unit consists of the Motor, the pump
housing with integrated motor housing and the appropria-
te impeller. All the significant components are generously
dimensioned.
