Safety and monitoring devices

Our products can be equipped with mechanical (e.g. intake
strainer) and/or electrical (thermo sensors, moisture sensors, etc.)
safety and monitoring devices. These devices must be attached
and connected.
Electrical devices such as thermo sensors or float switches must
be connected and tested by an electrician before start-up.
Please note that certain devices require a relay to function proper-
ly, for example a PTC thermistor and PT100 sensor. This relay can
be obtained from the manufacturer or an electrical supply dealer.
Personnel must be informed of the systems used and
how they work.
CAUTION!
never operate the product if the safety and moni-
toring devices have been removed or damaged, or
if they do not work.

Safety rules during operation

When operating the product, always follow the locally applicable
laws and regulations for work safety, accident prevention and
handling electrical machinery. To help to ensure safe working
practice, the responsibilities of employees should be clearly set
out by the owner. All personnel are responsible for ensuring that
regulations are observed.
The product has moving parts. During operation, these parts turn
to pump the fluid. Certain materials in the pumped fluid can cause
very sharp edges to form on the moving parts.
BEWARE of rotating parts!
The rotating parts can crush and sever limbs. never
reach into the hydraulics or the moving parts
during operation.
• Before performing maintenance or repairs, switch
off the product, disconnect it from the mains and
secure it against being switched on again without
authorization.
• Let the moving parts come to a stop!

2.10. operation in an explosive atmosphere

Products marked as explosion-proof are suitable for operation in
an explosive atmosphere. The products must meet certain guide-
lines for this type of use. Certain rules of conduct and guidelines
must be also followed by the operator.
Products that have been approved for use in an explosive atmo-
sphere are marked as follows:
• An "Ex" symbol must be attached to the name plate.
• Information on the explosion protection classification and
certification must be stated on the name plate.
When using a product in an explosive atmosphere,
observe the information on explosion protection
provided in the other sections.
BEWARE of using accessories not approved for use
in an explosive atmosphere!
If you use explosion-certified products in an ex-
plosive atmosphere, the accessories must also be
approved for this use. Check all accessories before
use to verify that they conform to this directive.

2.11. Pumped liquids

Each pumped liquid differs in respect of composition, corrosive-
ness, abrasiveness, dry matter content and in many other aspects.
Generally, our products can be used for many applications. Please
note that if requirements change (density, viscosity or general
composition), this can also affect many parameters of the prod-
uct.
When using or replacing the product in a different pumped liquid,
observe the following points:
• The pumped liquid can be contaminated by oil from the
oil separation chamber if the mechanical shaft seal is
defective.
Use in drinking water is not permitted!
• Products that have been operated in dirty waste water
must be cleaned thoroughly before being used for other
pumped liquids.
• Products that have been operated in sewage water and/or
fluids that are hazardous to health must be decontaminat-
ed before being used with other pumped liquids.
It must be clarified whether the product can be used
at all with another pumped liquid.
• It is strictly prohibited to pump explosive or highly flam-
mable liquids in pure form!
DAnGER - explosive liquids!
It is strictly prohibited to pump explosive liquids
(gasoline, kerosene, etc.). The products are not
designed for these liquids!

2.12. Sound pressure

Depending on the size and output (kW), the product generates a
sound pressure of approximately 70 dB (A) to 110 dB (A).
The actual sound pressure, however, depends on several factors.
These include the installation depth, configuration, fastening of
accessories and pipeline, operating point, immersion depth, etc.
Once the product has been installed, we recommend that the
operator make additional measurements under all operating
conditions.
CAUTIon: Wear ear protectors!
In terms of the applicable laws and regulations, ear
protection must be worn if the sound pressure is
greater than 85 dB (A). The owner is responsible for
ensuring compliance with these regulations.
