Safety
2 Safety
The manufacturer accepts no liability for damage caused
by disregarding any of the documentation.
2.1 Intended use
• Only use the pump with suitable media (ĺ resistance lists).
• When using the pumps for solid particles, agree use in
advance with the manufacturer.
• Do not use pump for combustible or explosive Àuids.
• Adhere to the operating limits and size-dependent minimum Àow rates.
• Avoid cavitation:
– Open the suction-side ¿tting and do not use it to regu-
late the Àow.
– Do not open the pressure-side ¿tting beyond the
agreed operating point.
• Avoid overheating:
– Do not operate the pump while the pressure-side ¿tting
is closed.
• Avoid damage to the motor:
– Do not open the pressure-side ¿tting beyond the
agreed operating point.
– Note the maximum permissible number of times the
motor can be switched on per hour (ĺ manufacturer's
speci¿cations).
• Only use the pump as part of large systems/tools.
• Consult with the manufacturer regarding any other use of
the device.
Prevention of obvious misuse (examples)
• Observe pump limits of use regarding temperature, pressure, Àow and speed (ĺ data sheet).
• The power consumption of the pump increases as the speci¿c gravity of the pumped Àuid increases. Adhere to th
e
permissible speci¿c gravity in ord er to eliminate th
epos-
sibility that the pump, coupling and motor become o
verloaded (ĺ data sheet).
A lo wer speci¿c gravity is permissible. Adapt
the auxiliary
systems accordingly.
• Pumps used with water as the pumped liquid must not be
used for foodstuffs o r drinking water. Use for food or drinking water only if speci¿ed in the data sheet.
• The type of installation should be selected only in accordance with these operating instructions. For example, the
following are not allowed:
– Hanging base plate pumps in the p ipe
– Overhead installation
– Installation in the immediate vicinity of extreme heat or
cold sources
– Installation too close to a wall
2.2 General safety instructions

7.2 S ervicing
Operating life of antifriction 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 op erating conditions. It is therefore not possible to make general statements about the operating life.
DANGER
Risk of injury due to running pump!
Do not touch the pump when it is running.
Do not carry out any work on the pump when it is running.
Before all installation and maintenance work, d isconnect
the motor from the mains and secure it against being
switched back on again.
DANGER
Risk of electrocution!
All electrical work must be carried out only by quali¿ed electricians.
Before all work on the electrical system, disconnect the
motor from the mains and secure against being switched
