Caution
Never operate the machine if the safety and moni-
toring 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 gene-
ral 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 hazar-
dous to health must always be decontaminated befo-
re 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 ope-
ration. 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, opera-
ting point, immersion depth, and much more.
3. General description
3.1. Use
The pumps are suitable for clear water from cisterns or
similar. They are used for domestic water supply, irriga-
tion, garden watering. The pumps must not be used for
pumping of liquids containing great quantities of abrasive
solids, like sand or stones. Before the pumping of chem-
ically aggressive liquids, the resistance of the pump ma-
terials must be checked.The pumps are suitable for both
mobile and stationary operation. Use in slurp mode is not
permitted.
The temperature of the pumped medium may be up to
35°C, short-term up to 60°C maximum. The maximum
density of the pumped medium is 1000 kg/m³ and the pH
value may range from 6 to 8.
3.2. Types of Application
The motors are designed for continuous operation (S1),
maximum 15 starts per hour.
3.3. Installation
The submersible aggregate consists of the motor, the
pump casing and the suitable impeller. All important parts
are of generous dimension.
