Safety
The manufacturer does not accept any liability for any dam-
age caused by disregarding any sections of the entire doc-
umentation.
2.1
Intended use
•
Only use the pump with suitable media (
→
resistance lists).
•
Do not use pump with solid particles or abrasive
fl
uids.
If pumps are to be used for solid particles, then agree use
in advance with the manufacturer.
•
Do not use pump with combustible or explosive
fl
uids.
•
Adhere to the operating limits and size-dependent mini-
mum
fl
ow rates.
•
Avoid dry running:
Initial damage, such as destruction of bearings, seals and
plastic parts, will occur within a few seconds.
–
Make sure the pump is only operated with, and never
without, pumped liquid.
•
Avoid cavitation:
–
Open suction-side
fi
tting fully and do not use to regulate
fl
ow.
–
Do not open the pressure-side
fi
tting beyond the
agreed operating point.
•
Avoid overheating:
–
Do not operate the pump while the pressure-side
fi
tting
is closed.
–
Note minimum
fl
ow (
→
Data sheet).
•
Avoid damage to the motor:
–
Do not open the pressure-side
fi
tting beyond the
agreed operating point.
–
Note the maximum permissible number of times the
motor can be switched on per hour (
→
manufacturer's
speci
fi
cations).
•
Consult the manufacturer about any other use of the pump.
•
If pumps are delivered without motors, then
fi
nal assembly
as a pump assembly must take place in accordance with
the provisions of machinery directive 2006/42/EC.
Prevention of obvious misuse (examples)
•
Observe pump limits of use regarding temperature, pres-
sure,
fl
ow and speed (
→
Data sheet).
•
The power consumption of the pump increases as the the
speci
fi
c gravity of the pumped
fl
uid increases. Adhere to
the permissible speci
fi
c gravity in order to eliminate the
possibility that the pump, coupling and motor are over-
loaded (
→
Data sheet).
A lower speci
fi
c gravity is permissible. Adapt the auxiliary
systems accordingly.
•
When conveying
fl
uids containing solids, observe the limit
values for proportions of solid particles and particle size
(
→
Data sheet, technical description).
•
When using auxiliary plant systems:
–
Ensure compatibility of the operating medium with the
product medium.
–
Ensure constant supply of the relevant operating
medium.
•
Pumps used with water as the pumped liquid must not be
used for foodstuffs or drinking water. Use with food or
drinking water must be speci
fi
ed in the data sheet.
•
Type of installation should only be selected in accordance
with these operating instructions. For example, the follow-
ing are not allowed:
–
Hanging base plate pumps in the pipe
–
Overhead installation
–
Installation in the immediate vicinity of extreme heat or
cold sources
–
Installation too close to the wall
2.2
General safety instructions
Observe of the following regulations before carrying out
any work.
2.2.1
Product safety
The pump has been built according to state-of-the-art technol-
ogy and the recognized technical safety regulations. Never-
theless, operation of the pump can still put the life and health
of the user or third parties at risk or damage the pump or other
property.
•
Only operate the pump if it is in perfect technical condition
and only use it as intended, staying aware of safety and
risks, and in adherence to the instructions in this manual.
•
Keep this manual and all other applicable documents com-
plete, legible and accessible to personnel at all times.
•
Refrain from any procedures and actions that would pose
a risk to personnel or third parties.
•
In the event of any safety-relevant faults, shut down the
pump immediately and have the fault corrected by appro-
priate personnel.
•
In addition to the entire documentation for the product,
comply with statutory or other safety and accident-preven-
tion regulations and the applicable standards and guide-
lines in the country where the pump is operated.
