Installation and operating instructions SIE-DIE-PBE
• The pump should only be installed after completion of all welding and
soldering work and, if necessary, flushing of the pipe system. Dirt can
cause pump failure.
• The pumps must be protected from the weather and installed in a
frost/dust-free, well-ventilated atmosphere which is not potentially
explosive. The pump must not be installed outdoors.
• Install the pump in a place that is easy to access so that subsequent
inspections, maintenance (e.g. mechanical seal) or replacement is
easily possible. The air access to the dissipator of the electronic mod-
ule may not be limited.
• A hook or a lug with sufficient load-bearing capacity must be installed
vertically over the pump (total weight of the pump: see catalogue/
data sheet), to which the pump lifting gear or similar equipment can
be attached during maintenance or repair of the pump.
CAUTION! Risk of property damage!
Danger of damage due to incorrect handling.
• Only use lifting eyes on the motor for carrying the weight of the
motor and not for carrying the entire pump (Fig. 16).
• The pump is only to be lifted with approved load-bearing equip-
ment.
• Minimum axial distance between a wall and the fan cover of the
motor: Free dismantling dimension of at least 200 mm + diameter of
the fan cover.
NOTE
Shut-off devices shall be installed in front of and behind the pump in
all cases, in order to avoid having to drain the entire system when
checking or renewing the pump.
A non-return valve shall be installed on the pressure side of each pump.
NOTE
A settling section must be provided before and after the pump, in the
form of a straight pipe. The length of this settling section should be at
least 5 x DN of the pump flange (Fig. 17). This measure serves to avoid
flow cavitation.
• The pipes and pump must be free of mechanical stress when installed.
The pipes must be fastened in such a way that the pump does not
bear the weight of the pipes.
• The direction of flow must correspond to the direction arrow on the
pump housing flange.
• The bleed valve (Fig. 18, Item 1) must always face upwards.

• All installation positions except for "motor facing down" are allowed.
• The installation position with horizontal motor shaft is only permitted
up to a motor power of 15 kW. A motor support is not necessary.
• Only the installation position with vertical motor shaft is intended for
a motor power >15 kW.
NOTE
PBE series monobloc pumps are to be mounted on a sufficiently
strong base or mounting brackets.
• The electronic module must not face downwards. If required, the
motor can be turned after loosening the hexagon head bolts.
NOTE
After loosening the hexagon head bolts, the differential pressure sen-
sor is attached to the pressure measuring lines only. When turning the
motor housing, make sure that the pressure measuring lines are not
bent or kinked. Furthermore, while rotating the motor housing, it must
be ensured that the housing O-ring seal does not become damaged.
