General safety instructions
The manufacturer accepts no liability for damages caused
by disregarding any of the documentation.
2.1
Intended use
•
Only use the pump with suitable media. Pump parts in con-
tact with media must be resistant to the media. (
→
Order
specification).
•
Use the pump for flammable or explosive media only if it
is intended for use in potentially explosive atmospheres
(
→
ATEX additional instructions).
•
Adhere to the operating limits and size-dependent mini-
mum flow rates.
•
Avoid dry running:
Initial damage, such as destruction of plain bearings, seals
and plastic parts, will occur within a few seconds.
–
Make sure the pump is only operated only when filled
with the conveyed fluid and vented, and never operated
when not filled with the pumped liquid.
–
Ensure that there are no excessively high amounts of
gas in the pumping medium.
–
Ensure that the pump is operated only within the per-
missible operating range.
–
Ensure that the use of shut-off valves or filters does not
cause the pressure on the inlet side of the pump to be
too low.
•
Avoid cavitation:
–
Open the suction-side fitting and do not use it to regu-
late the flow.
–
Do not open the pressure-side fitting beyond the
agreed operating point.
•
Avoid overheating:
–
Do not operate the pump while the pressure-side fitting
is closed.
–
Note minimum flow (
→
Data sheet).
•
Avoid damage to the motor:
–
Do not open the pressure-side fitting beyond the
agreed operating point.
–
Note the maximum permissible number of times the
motor can be switched on per hour (
→
manufacturer's
specifications).
•
Consult with the manufacturer regarding any other use of
the device.
Prevention of obvious misuse (examples)
•
Observe pump limits of use regarding temperature, pres-
sure, flow and speed (
→
data sheet).
•
The power consumption of the pump increases as the spe-
cific gravity of the pumped fluid increases. Adhere to the
permissible specific gravity in order to eliminate the pos-
sibility that the pump, coupling and motor become over-
loaded (
→
data sheet).
A lower specific gravity is permissible. Adapt the auxiliary
systems accordingly.
•
When conveying fluids containing solids, observe the limit
values for proportions of solid particles and particle size:
–
Particle size
≤
3 mm
–
Proportion of solid particles
≤
10 % Vol.
•
The type of installation should be selected only in accor-
dance with these operating instructions. For example, the
following are not allowed:
–
Hanging pumps in the pipe
–
Overhead installation
–
Installation in the immediate vicinity of extreme heat or
cold sources
–
Installation too close to a wall
–
Vertical installation
2.2
General safety instructions
Observe 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.
•
Operate the pump only if it is in perfect technical condition
and use it only 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.
2.2.2
Obligations of the operating company
Safety-conscious working
•
Operate the pump only if it is in perfect technical condition
and use it only as intended, staying aware of safety and
risks, and in adherence to the instructions in this manual.
•
Ensure that the following safety aspects are observed and
monitored:
–
Intended use
–
Statutory or other safety and accident-prevention reg-
ulations
–
Safety regulations governing the handling of haz-
ardous substances
–
Applicable standards and guidelines in the country
where the pump is operated
–
Applicable guidelines of the operator
•
Make personal protective equipment available.
