Warning

The material property of a liquid (e.g. viscosity, lubricating property, particle

content, corrosiveness) impacts the technical data and the service life of

pumps.

At 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.
