4.4 Accessories (optional)
• Suction kit
• Shut-off device
• Diaphragm pressure vessel
• Tank
• Non-return valve
• Foot valve with suction strainer
• Compensator
• Protection against low water level
(potable water network)
(see Fig. 5, Pos. 21)
• Pressure sensor control kit (sensor precision:
#
1%; utilisation between 30% and 100% of the
reading range).
5 Installation
Two types:
•
see Fig 1: Suction mode.
•
see Fig. 2: Pressure operation from replenish-
ment vessel
(Pos. 9) or potable water network
(Pos. 10).
5.1 Installation
Install the pump at a readily accessible location
which is protected against external influences
(excessive rain or sunlight, frost) and which is as
near as possible to the extraction point.
Place the pump on a pedestal
(Pos. 13) or directly
on a smooth, level base. Fixation of the pump
with 2 holes for Ø M8 bolts.
Note that the height of the installation
location and the temperature of the
fluid will diminish the suction capacity
of the pump.
Installation should be carried out in
pressure operation when temperatures
exceed 80°C.
5.2 Pipe connections
The installation must be sufficient for
the pressure that the pump generates
at maximum frequency and zero flow
volume.
- Connection with spiral-reinforced flexible hoses
or rigid pipe.
-
Seal the pipe connections well with suitable
products. No air is permitted to enter the suc-
tion line; lay the suction line with a continuous
rise (2%) (see Fig. 1).
- In the case of rigid pipes, take care to ensure that
the weight of the lines is not borne by the pump
alone. Utilise supports and/or pipe brackets
(see
Figs. 1 + 2, Pos. 7).
