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 (
→
resistance lists).
•
Do not use pump with solid particles.
•
Do not use pump for combustible or explosive fluids.
•
Adhere to the operating limits and size-dependent mini-
mum flow 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.
–
Ensure that the sealing chamber is sufficiently filled.
–
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 insertion of valves or filters does not
make the pressure too low on the inlet side of the pump.
–
Ensure that high temperatures and/or low suction pres-
sures of the pumped medium do not cause the vapor
pressure to fall below the minimum value, and that gas
bubbles are formed at the pairs of bearings.
•
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.
•
If pumps are delivered without motors, then final assembly
as a pump assembly must take place in accordance with
the provisions of the Machinery Directive 2006/42/EC.
•
Use the pump only as part of a large system/tool.
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.
•
Do not use the pumps to pump media containing solid par-
ticles.
•
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 for food or drink-
ing water only if specified in the data sheet.
•
The type of installation should be selected only in accor-
dance with these operating instructions. For example, the
following 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 a wall
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.
