2.7. Safety and control devices
Our products are equipped with various safety and control devices. These include, for example suction strainers,
thermo sensors, sealed room monitor etc. These devices must never be dismantled or disabled.
Equipment such as thermo sensors, float switches, etc. must be checked by an electrician for proper functioning
before start-up (see the "Electrical Connection" data sheet). Please remember that certain equipment requires a
decoder device or relay to function properly, e.g. posistor and PT100 sensor. This decoder can be obtained from
the manufacturer or a specialist electronics dealer.
Personnel must be informed of the installations used and how they work.
Caution
Never operate the machine if the safety and monitoring devices have been removed or damage, or if they
do not work.
2.8. Operation in an explosive atmosphere
Products marked as explosion-proof are suitable for operation in an explosive atmosphere. The products must
meet certain guidelines for this type of use. Certain rules of conduct and guidelines must be adhered to by the
operator as well.
Products that have been approved for operation in an explosive atmosphere are marked as explosion-protected
"Ex". In addition, an "Ex" symbol must be included on the type plate! When used in an explosive atmosphere, the
additional chapter entitled "Explosion protection according to the ...standard" must be observed!
2.9. Pumped fluids
Each pumped fluid differs in regard to composition, corrosiveness, 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
general composition change, this can also alter many parameters of the product.
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 hazardous 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 lubricant 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!
3. General description
3.1. Application
Submersible mixers are used for various applications such as mixing, homogenization and suspension of liquids
with low to medium viscosity. Max. 6% liquids in the medium!
3.2. Types of Use
The motors are designed for continuous operation (S1), maximum 15 starts per hour.
3.3. Construction
The pump consists of the motor and the pump housing as well as the propeller which belongs to it.
All important parts of the pump are characterized by generous dimensioning.
