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. Utilization

The pumps are suitable for conveying clean or soiled wa-
ter with abrasive contamination of sand or sludge. Scope
of application: e.g. gravitation drainage, dewatering of
construction sites, subways or sewers, emergency use in
the event of flooding. With chemically aggressive compo-
nents in the pumped medium, the resistance of the pump
materials used must be noted at all times. The pumps
are suitable for both mobile and stationary operation.
Free-standing installation on a firm base is possible. Use
in slurp mode is permitted.
The temperature of the pumped medium may be up to
40°C, short termed up to max. 60°C. The maximum den-
sity of the pumped medium is 1,040 kg/m3 and the pH
value may be 6 to 8. The pump is made of different mate-
rials, depending on the version.
For the TP8/1, the exterior shell is made of stainless steel;
the TP 4/1 shell is made of hard PVC.

3.2. Type of application

The pumps are designed for operating mode S S1 (con-
tinuous operation) with a max. switching frequency of 15
circuits/hour.

3.3. Structure

The submersible aggregate consists of the motor, the
pump casing and the suitable impeller. All important parts
are of generous dimension.
