General safety instructions
2 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
