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
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 technology and the recognized technical safety regulations. Nevertheless, 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

• 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 in structions in this manual.
• Keep this manual and all other applicable documents complete, 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 b y appropriate personnel.
• In addition to the entire documentation for the product,
comply with statutory or other safety and accident-prevention regulations and the applicable standards and guidelines in the country where the pump is operated.

tection
– For potential electrostatic charging: provide suitable
grounding
Warranty
• Obtain the manufacturer's approval prior to carrying out
any modi¿cations, repairs or alterations during the warranty
period.
• Only use genuine parts or parts that have been approved
by the manufacturer.
2.2.3 Obligations of personnel
• All directions given on the pump must be followed (and kept
legible), e.g. the arrow indicating the sense of rotation and
the markings for Àuid connections.
• Pump, coupling guard a nd com ponents:
– Do not step on them or use as a climbing aid
– Do not use them to support boards, ramps or beams
– Donotusethemasa¿xing point for winches or sup-
ports
– Do not use them for storing paper or similar materials
– Do not use the hot pump or motor components as a
heating point
– Do not de-ice the pump using gas burners or similar
tools
• Do not remove the safety guarding for hot, cold or moving
parts during operation.
• Use personal protective equipment if necessary.
• Only carry out work on the pump while it is not running.
• Before all installation and maintenance work, disconnect
the motor from the mains and secure it against being
switched back on again.
• Never reach into the suction or discharge Àange.
• Following all work on the pump, re¿t safety devices in
accordance with the instructions and bring into service.
• Do not make any modi¿cations to the device.
2.3 Speci¿chazards
2.3.1 Hazardous pumped liquids
• When handling hazardous Àuids, observe the safety regulations for the handling of hazardous substances.
• Use personal protective equipment when carrying out any
work on the pump.
• Collect leaking pumped liquid and residues in a safe manner and damage them in accordance with environmental
regulations.
