The manufacturer does not accept any liability for dam-
age resulting from non-observance of the entire documen-
tation.
2.1 Intended use
• Only use the pump to pump the agreed pumped liquid
(→order data sheet).
• Adhere to the operating limits and size-dependent mini-
mum flow rate.
• Avoid dry running:
Initial damage, such as destruction of plain bearings and
plastic parts, within a few seconds.
– Make sure the pump is never put into operation or oper-
ated without pumped liquid.
• Avoid cavitation:
– Fully open the suction-side fitting; do not use the fitting
to adjust the flow rate.
– 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.
– Observe the minimum flow rate (→order data sheet).
• To avoid damage to the motor:
– Do not open the pressure-side fitting beyond the
agreed operating point.
– Observe the number of permitted motor start-ups per
hour (→manufacturer's specifications).
• Consult the manufacturer about any other use of the pump.
Avoiding common types of misuse (examples)
• Observe the operating limits of the pump regarding oper-
ating temperature, pressure, flow rate and speed (→order
data sheet).
• The power uptake of the pump increases with increasing
density of the pumped liquid. To avoid any overload for the
pump and motor, do not exceed the permissible density
(→order data sheet).
A lower density is allowed. Adapt the auxiliary systems
accordingly.
• Adhere to the limits for solids content and grit size when
pumping solids-carrying fluids (→order data sheet, techni-
cal description).
• When using auxiliary operating systems:
– Ensure the flushing medium is compatible with the
product medium.
– Ensure there is a permanent supply of the respective
flushing 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 the latest tech-
nology and established technical safety rules. Nevertheless, a
potential risk to life and limb of the operator or to other persons
or damage to the pump and other property cannot be entirely
excluded.
• Only operate the pump if it is in perfect technical condition;
only use it as intended, staying aware of safety and risks,
and adhering to the instructions in this manual.
• Keep this manual and all other applicable documents com-
plete, legible and accessible to staff at all times.
• Refrain from any procedures that would endanger staff or
third parties.
• If a safety-relevant fault occurs, shut down the pump imme-
diately and have the fault corrected by appropriate staff.
• In addition to the entire documentation for the product,
always comply with statutory or other safety and accident-
prevention regulations as well as with the applicable stan-
dards and guidelines in the country where the pump is
operated.

the arrow indicating the direction of rotation and the indica-
tion of fluid connections.
• Do not remove the protection against accidental contact for
hot, cold and moving parts during operation.
• Use protective equipment if necessary.
• Carry out work on the pump only while the pump is not
running.
• Isolate the motor from its supply voltage and keep it locked
in that state while carrying out any fitting or maintenance
work.

DANGER
Risk of fatal injury and material damage due to magnetic
field!
Make sure no-one with a heart pacemaker performs any
work on the pump.
Secure the workplace and cordon it off if necessary:
– Ensure staff with heart pacemakers keep a minimum
distance of 1 m.

CAUTION
Material damage due to base plate distortion!
Place the base plate on the foundation and fasten it as
described in the following.
5.2.1 Setting the pump group down on the foundation
✔Implements, tools and materials:
– Foundation bolts (→setup drawing)
– Steel washers
– Mortar grout, non-shrinking
– Spirit level
1. Lift the pump group (→4.1 Transport, Page 10).
2. Hang the foundation bolts in the fixation holes of the base
plate from below.
Observe the specifications of the manufacturer when using
chemical anchors.
3. Set the pump group down on the foundation, sinking the
foundation bolts into the prepared anchoring holes.
32 1 2
Fig. 7 Setup with foundation
4. Use steel washers to align the pump group to the height
and system dimensions as described in the following:
– Position one steel washer (2) to the left and right of
each foundation bolt (1).
– If the distance between the anchoring holes is greater
than 750 mm, position additional steel washer (3) at
the centre of each side of the base plate.
5. Make sure the base plate and steel washers are in full sur-
face contact.
6. Use a machine spirit level to check the permissible height
deviation (1 mm/m) lengthwise and crosswise.
7. Repeat the procedure until the base plate is aligned cor-
rectly.
5.2.2 Fastening the pump group
The damping behaviour is improved by filling out the base
plate with mortar grout.
1. Fill the anchoring holes with mortar grout.
2. Once the mortar grout has set, screw the base plate
tight at three points with the specified tightening torque
(→9.2.3 Tightening torques, Page 34).
3. Before tightening the remaining screws, compensate any
unevenness of the fixation surface with metal shims next
to each screw.
4. Make sure the base plate is not distorted.

5.4.1 Avoid impurities in the pipes
CAUTION
Damage due to impurities in the pump!

CAUTION
Material damage due to excessive forces and torques of
the pipes on the pump!
Do not exceed the permissible limits (→9.2.5 Socket loads
according to ISO 5199, Page 34).
1. Calculate the pipe forces and take into account all operat-
ing conditions:
–Cold/warm
–Empty/full
– Unpressurised/pressurised
– Position shifts of flanges
2. Ensure the pipe can slide freely in the supports and does
not seize up due to corrosion.

stop valve to ensure the medium does not flow back after
thepumpisswitchedoff.
2. To allow bleeding, provide a bleeding connection between
the pressure joint and non return valve.
Make provisions for isolating and shutting off the pipes
For maintenance and repair work
Fit stop valves in the suction pipe and pressure pipe.
Enable measurements of the operating conditions
1. For pressure measurements, fit manometers in the suction
pipe and pressure pipe.
