2 Safety
The manufacturer does not accept any liability for any damage caused by disregarding any sections of the entire documentation.
2.1 Intended use
• Only use the pump with suitable media (→ resistance lists).
• Do not use pump with solid particles or abrasive fluids.
• Do not use pump with combustible or explosive fluids.
• Adhere to the operating limits and size-dependent minimum 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.
• Avoid cavitation:
– Open suction-side fitting fully and do not use to regulate
flow.
– D o 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.
–Noteminimumflow (→ Data sheet).
• Avoid damage to the motor:
– D o 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 the man ufacturer about any other use of the pu mp.
• If pumps are delivered without m otors, then final 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 temperat
sure, flow and speed (→ Data sheet).
• The power consumption of the pump increases as the the
specific gravity of the pumped fluid increases. Adhere to
the permissible specific gravity in order to eliminate the
possibility that the pump, coupling and mo tor are overloaded (→ Data sheet).
A lower specific gravity is perm issible. Adapt the auxiliary
systems accordingly.
• When conveying fluids containing solids, observe the limit
values for proportions of solid particles and particle size
(→ Data sheet, technical description).
•Whenusinga

ure, pres-
• Pumps used with water as the pumped liquid must not be
used for foo dstuffs or drinking water. Use with food or
drinking water must be specified in the data sheet.
• Type o f installation should only be selected in accordance
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 the wall

7 Maintenance
Maintenance
Trained service technicians are available for fitting and
repair work. Submit evidence of conveyed medium on
request (DIN safety data sheet or safety certificate).
7.1 Inspections
The inspection intervals depend on the operational strain
on the pump.
DANGER
Risk of injury due to running pump!
Do not touch the running pump.
Do not carry out any work on the running pump.
WARNING
Risk of injury and poisoning due to hazardous pumped
liquids!
Use protective equipment for any work on the pump.
1. Check at appropriate intervals:
– Adherence to the min imum flow rate
– Normal operating conditions unchanged
– Filling level of the container
2. Fo r trouble-free operation, always ensure the fo llowing:
–Noleaks
– No cavitation
– Free and clean filters
– No unusual running n oises or vibrations
– No inadmissible leaks on the shaft seal
7.2 Maintenance
Operating life of an tifrictio n bearings in operation are within
permissible range: >2 years.
Intermittent operation, high temperatures, low viscosities
and aggressive ambient and process conditions reduce the
service life of antifriction bearings.
Plain bearings are subject to natural wear and tear which
is heavily dependent on the respective operating conditions. It is therefore not possible to make general statements about the operating life.
DANGER
Risk of injury from running pump
Do not touch the running pump.
Do not carry out any work on the running pump.
Before all installation and maintenance work, discon-
nect the mo tor from the mains and secure against being
switched back on again.
DANGER
Risk of electrocution!
All electrical work must be carried out by qualified electricians only.
Before all work on the electrical system, disconnect the
motor from the mains and secure against being switched
back on again.
DANGER
Danger to life from rotating parts
Ensure coupling guard is fitted after work on the pump.
WARNING
Risk of injury and poisoning due to hazardous or hot fluid.
Use protective equipment for any work on the pump.
Allow the pump to co ol down completely before commenc-
ing any work.
Make sure the pump is unpressurized.
Empty the pump, s afely collect the pumped liquid and
dispose of it in accordance with environmental rules and
requirements.
