Warning
The material properties of a liquid (e.g. viscosity, lubricating property, particle
content, corrosiveness) impacts the technical data and the lifetime of pumps.
Under appropriate conditions the characteristic values may be increased or
decreased.
Warning
If you intend to operate the pump out of the range of the above given
specification, please consult the manufacturer. Modifications may be necessary
to ensure successful operation. Otherwise the pump or the system may be
damaged seriously.
