Sound pressure
Depending on the size and output (kW), the pump has a sound pressure of approx. 60dB (A) to 110dB (A) during
operation. However, the actual sound pressure depends on several factors. These include e.g. type of installation
and set-up, attachment of accessories, pipes, operating point, submersion depth etc. We recommend that the
operator performs an additional measurement at the place of work when the product is running in its operating point
and under all operating conditions.
Caution: Wear hearing protection!
Hearing protection is obligatory as of a sound pressure of 85dB (A) according to valid legislation and regulations!
The owner-operator must ensure that this is observed.
2.10 Pumping media
All pumping media differ on account of their composition, aggressiveness, abrasiveness and many other aspects.
Generally speaking, our pumps can be used in many areas. Please see the pump data sheet for more detailed
information. It must be noted that a change in density, viscosity or the composition in general can lead to changes
in many of the pump’s parameters.
In addition, different materials and impeller shapes are required for the different media. The more precise the
details in your order, the better we can modify our pump to your requirements. If there should be any changes in
the area of application and/or pumping medium, we will be happy to provide assistance.
Risk due to explosive media!
The pumping of explosive media (e.g. petrol, kerosene etc.) is strictly prohibited. The products have not been
designed for these media.
