3 Transport and interim storage
When receiving the material, check that there has
been no damage during the transport. If shipping
damage has occurred, take all necessary steps with
the carrier within the allowed time.
Handle the pump carefully so as not to damage the
unit prior to installation.
4 Intended use (Application)
Typical applications for the MVI pumps are clean flu-
ids relatively free of abrasive particles in commercial,
agricultural, industrial and municipal areas. Water
supply, water towers, irrigation, high pressure wash
down, fire protection, boiler feed, condensate return
and pressure boosting systems.
Application areas:
• water distribution and boosting installations
• industrial circulation systems
• process fluids.
• cooling water circuits.
• fire-fighting and washing stations.
• watering installations, etc.
5 Technical data
5.1 Type key
CAUTION! Outside influences may cause damages
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.).
WARNING! Bodily injury
Due to the high centre of gravity and small pump
footprint, beware of instability during handling to
avoid the pump falling over.
CAUTION! Possible damage of the pump
These pumps are intended for use with water only
