Safety
2Safety
The manufacturer does not accept any liability for damage
resulting from disregard of the entire documentation.
2.1 Intended use
• Only use the pump to pump the agreed pumped liquids
(→order data sheet).
• Adhere to the operating limits and size-dependent mini-
mum flow rate.
• Avoid dry running:
Initial damage, such as destruction of seals and plastic
parts, will occur within only a few seconds.
– Make sure the pump is only operated with, and never
without, pumped liquid.
• Avoid cavitation:
– Fully open the suction-side fitting and do not use it 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).
• 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 the manufacturer about any other use of the pump.
• When a pump is delivered without a motor, the pump unit
must be completed in accordance with the stipulations of
machine directive 2006/42/EC.
Prevention of obvious misuse (examples)
• Note the operating limits of the pump with regard to temper-
ature, pressure, flow rate and motor speed (→order data
sheet).
• The power consumed by the pump increases with increas-
ing specific gravity of the pumped medium. To avoid over-
loading the pump, coupling or motor, stay within the agreed
density (→order data sheet).
Lower densities are allowed. Adapt the auxiliary systems
accordingly.
• When pumping liquids containing solids, ensure the limits
for the proportion of solids and the grain size are main-
tained (→order data sheet, technical description).
• When using auxiliary systems, ensure there is a continuous
supply of the appropriate operating medium.
• Pumps used with water as the pumped liquid must not be
used for foodstuffs or drinking water. Use of the pump for
foodstuffs or drinking water must be specified in the order
data sheet.
• Only select the setup type according to this operating man-
ual. 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 the wall

DANGER
Risk of death and material damage due to magnetic field!
Make sure that personnel who have a pacemaker do not
perform any work on the pump.
Secure the work area. If necessary isolate the area:
– Make sure that personnel with pacemakers keep a safe
distance of at least 1 m.
– Make sure that no magnetizable metal parts can be
attracted by the magnetic coupling of the pump.
– Make sure that parts of the magnetic coupling cannot
be attracted by the magnetizable metal parts.
Keep all magnetically-sensitive objects at a safe distance
of at least 150 mm from the magnetic coupling.
NOTE
Material damage due to distortion of the base plate!
Place the base plate on the foundation and secure it as
described in the following.
5.2.1 Placing the pump unit on the foundation
Implements, tools and materials:
– Foundation bolts (→setup drawing)
– Steel washers
– Non-shrinking mortar grout
– Spirit level
1. Lift the pump unit (→4.1 Transport, Page 13).
2. Attach the foundation bolts from below into the base plate
fixing holes.
Observe the manufacturer's instructions when using adhe-
sive anchors.
3. Set the pump unit down on the foundation. When doing
so, sink the foundation bolts into the prepared anchoring
holes.

4. Use steel washers to align the pump unit to the height and
system dimensions as described in the following:
– Placeasteelwasher(2)totheleftandright-handside
of each foundation bolt (1).
– If the distance between the anchoring holes is greater
than 750 mm, place additional steel washers (3) in the
middle, on each side of the base plate.
5. Make sure the steel washers lie flat against the base plate,
in full contact.
6. Use the integrated spirit level to check whether the pump is
level end to end and side to side with a maximum allowable
tilt of 1 mm/m.
7. Repeat the procedure until the base plate is correctly
aligned.

Setup and connection
5.2.2 Fastening the pump unit
The damping behavior is improved by filling the base plate
with mortar grout.
1. Fill the anchoring holes with mortar grout.
2. When the mortar grout has set, screw down the base plate
at three points with the specified torque.
3. Before tightening the remaining bolts, compensate for any
unevenness in the surface using metal spacing shims next
to each bolt.
4. Fasten all bolts tightly.
5. Turn the pump by hand:
– Ensure the pump can be turned without pressure
points.
5.3 Planning the piping
5.3.1 Specifying supports and flange connections
NOTE
Material damage due to excessive forces and torques
exerted by the piping on the pump!
Do not exceed the permissible limits (→9.2.5 Flange loads
according to ISO 5199, Page 42).
1. Calculate the pipe forces, taking every possible operating
condition into account:
–Cold/warm
– Empty/full
– Depressurized/pressurized
– Positional changes of the flanges
2. Ensure the pipe supports have permanent low-friction
properties and do not seize up due to corrosion.
5.3.2 Specifying nominal diameters
Keep the flow resistance in the pipes as low as possible.
1. Where possible, make sure the nominal suction pipe diam-
eter is ≥as possible to the nominal suction flange diameter.
– Recommended flowratespeed<1m/s
2. Make sure the nominal pressure pipe diameter is ≥as pos-
sible to the nominal pressure flange diameter.
– Recommended flowratespeed<3m/s
5.3.3 Specifying pipe lengths

B
A
Fig. 11 Straight pipe lengths upstream and downstream
of the pump (recommended)
A > 5 x nominal suction pipe diameter
B Nominal suction pipe diameter
C Nominal pressure pipe diameter
D > 5 x nominal pressure pipe diameter
Maintain the recommended minimum values when
installing the pump.
Suction side: shorter pipes are possible but may restrict
the hydraulic performance.
Pressure side: shorter pipes are possible but can result in
increased operating noise.
5.3.4 Optimizing cross-section and direction changes
1. Avoid bending radii of less than 1.5 times the nominal pipe
diameter.
2. Avoid abrupt changes of cross-section along the piping.

5.3.5 Discharging leaks
WARNING
Risk of injury and poisoning due to hazardous pumped
liquids!
Safely collect any leaking pumped liquid, then discharge
and dispose of it in accordance with environmental regula-
tions.
1. Provide equipment for collecting and discharging leaking
liquids.
2. Ensure the free discharge of leaking liquids.
5.3.6 Providing safety and control devices
(recommended)
Avoid impurities
1. Integrate a filter in the suction pipe.
2. To monitor impurities, install a differential pressure gauge
with a contact manometer.
Avoiding reverse running
Install a non-return valve between the outlet flange and the
gate valve to ensure the medium does not flow back when
the pump is switched off.
Avoid running empty
For suction operation: install a foot valve in the suction pipe
to prevent the pump and suction pipe from running empty
during downtimes.
Making provisions for isolating and shutting off pipes
For maintenance and repair work.
Provide shut-off devices in the suction and pressure pipes.
Allow measurement of the operating conditions
1. Provide manometers for pressure measurements in the
suction and pressure pipes.
2. Provide load monitors (overload and underload) on the
motor side.
3. Provide for pump-side temperature measurements.
Recognizing and disposing of leaks
Leaks in the separating can may enter the motor and dam-
age it.
1. Connect the leak disposal line onto the LM1 leak drain.
2. Provide a leak sensor.
3. Switch off the pump in case of leaks.
5.4 Installing in the pipe
CMIT series only.
