The manufacturer does not accept any liability for events
resulting from disregard of the entire documentation.
2.1 Intended use
• Only use the pump for pumping the agreed pumped media
(→ Order data sheet).
• Adhere to operating limits and size-dependent minimum
flow rate.
• Avoid dry running:
Initial damage such as destruction of mechanical seal and
plastic parts within only a few seconds.
– Make certain that the pump is never put into operation
and never operated without a pumped medium.
• To avoid cavitation:
– Fully open the suction-side armature and do not use
for adjusting the flow rate.
– Do not open the pressure-side armature beyond the
agreed operating point.
• To avoid overheating:
– Do not operate the pump while the pressure-side arma-
ture is closed.
– Observe the minimum flow rate (→ Ord er data sheet).
• To avoid damage to the motor:
– Do not open the pressure-side armature beyond the
agreed operating point.
– Observe the allowed number of motor switch-ons per
hour (→ Manufacturer's specifications).
• Consult with the manufacturer about any other use of the
pump.
Prevention of self-evident misuse (examples)
• Observe the operating limits of the pump regarding operat-
ing temperature, pressure, flow rate and speed (→ Order
data sheet).
• The power uptake of the pump will i ncrease with increasing
density of the pumped medium. To avoid any overload for
the pump, the coupling and the motor, do not exceed the
allowable density (→ Order data sheet).
A lower density is allowed. Adapt auxiliary system s accord-
ingly.
• Adhere to limits on solids content and grit size when pump-
ing solids-carrying fluids (→ Order data sheet, technical
description).
• When using auxiliary operating systems, ensure that
there is a continuous supply of the appropriate operating
medium.
2.2 General safety instructions
Take note of the following instructions before carrying out
any work.
2.2.1 Product safety
The pump has been constructed according to up-to-date tech-
nology and established technical safety rules. Nevert heless,
operation of the pump can involve risks to life and health of the
user or of third parties, or risks of damaging the pump and other
property.
• Operate the pump only if it is in perfect technical condition,
according to its intended use, in awareness 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
expose personnel or third parties to any risk.
• Should there be any safety-relevant fault, deactivate the
pump immediately and have the fault corrected by appro-
priate personnel.
• In addition to the entire documentation for the product,
always comply with statutory or other safety and acci-
dent-prevention rules and with the applicable standards
and guidelines in the country where the pump is operated.
