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 be-
fore 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 op-
eration. However, the actual sound pressure depends on
several factors. These are, for example, the type of instal-
lation and set-up, mounting of accessories, piping, operat-
ing point, immersion depth, and much more.

3. General Description

3.1. Usage

The pumps are used as a precaution and to protect against
small quantities of water or leaking water in rooms in
which no pump chamber is present, e.g. in cellars or base-
ment rooms during downpours, rooms with lines carrying
water or appliances (e.g. washing machines, household
water machines) to protect against the consequences of
pipe damage or leaks. Due to the height adjustment of the
pump feet, shallow water pumping to 1mm is possible.
Abrasive or other substances that attack materials may
destroy the pump. The pump is not suitable for use in
conveying media with abrasive dirt, sand, mud or loam
admixtures.
Permitted for use in sloshing operations.
The maximum density of the conveying medium is 1040
kg/m³.

3.2. Usage Types

The pump is designed with a conveying rate of at least
1 l/min for operating mode S1 (continuous) with a max.
switching frequency of 15 switches/hour with a conveying
medium temperature of up to 35°C.
If the conveying rate is below 1 l/min or the temperature
of the medium is between 36°C and a maximum of 60°C,
the operating modes S2 (short-time operation) and S3 (in-
termittent operation) are permitted. Please find the pre-
cise data in the tables in Chapter 3.3.1 Motor.
