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. Use
The pumps are suitable for conveying clean water from
wells, cisterns or tanks. Examples of their areas of applica-
tion include supplying domestic water, irrigating gardens
and exploiting rainwater.
The pumps are not suitable for conveying media contain-
ing seriously abrasive fractions (e.g. sand, gravel, stones).
If the conveyed medium contains chemically aggressive
fractions, the ability of the pump materials to withstand
them is without fail to be respected. The pumps are suit-
able for both transportable and stationary operation.
Their use in slurp operation is not permitted.
The temperature of the conveyed medium may be up to
30°C. The maximum density of the conveyed medium is
1000 kg/m³ and its pH value may be 6 - 8.
3.2. Types of use
The pumps are designed for the S1 (continuous) mode of
operation. You can find precise data in the Table in section
3.3.2 Motor.
3.3. Construction
The fully submersible unit consists of the motor, the pump
housing and the appropriate blade wheel. All important
components are generously dimensioned.
