If the delivered material is to be installed later on,
store it in a dry place and protect it from impacts
and any outside influences (humidity, frost etc.).
Handle the pump carefully so as not to damage the
unit prior to installation.

water or other low viscosity fluids that contain no
mineral oil, abrasive substances or materials having
long fibres. The manufacturer's approval is required
for use to pump corrosive chemicals.
Application areas:
• water distribution and boosting installations
• industrial circulation systems
• process fluids
• cooling water circuits
• fire-fighting and washing stations
• watering installations, etc.
