5.4 Accessories
Accessories must be ordered separately as
required. The accessories from the Wilo range
include the following:
• open break tank (example Fig. 10a),
• larger diaphragm pressure vessel (on the suction
or discharge side),
• safety valve,
• dry-running protection:
• protection against low water level (WMS)
(Fig. 5a to 5c), in inlet mode (at least 1.0 bar) for
COR-1 MHIE (Fig. 5b) and SiBoost Smart 1…EM2
(Fig. 5a) systems (is supplied fitted to the
pressure-boosting system if part of the order).
For SiBoost Smart 1 HELIX VE…/COR-1 MVIE…
systems: a supply pressure sensor is fitted on
the suction side as standard, functioning as a
low-water cut-out switchgear during operation
with supply pressure (Fig. 2b).
For COR/T-1… systems: a float switch that
switches the pump off when there is a water
shortage (Fig. 1e, item 52) and a pressure sensor
on the suction side (Fig. 1e, item 12-2) that
switches the pump back on when the supply
pressure reaches at least 0.3 bar, are installed in
the break tank as standard.
• float switch,
• low-water electrodes with level relay,
• electrodes for tank operation (special
accessories on request),
• main switch (Fig. 1a to 1h; Fig. 16),
• flexible connection pipes (Fig. 8-31),
• compensators (Fig. 8-30),
• threaded flanges,
• sound-insulating unit casing (special accessories
on request).
6 Description of the product and accessories
6.1 General description
The system with its non-self-priming, vertically
(Helix VE, MVIE or MVISE) or horizontally (MHIE)
mounted high-pressure multistage centrifugal
pump with frequency converter is supplied with all
pipework installed as a compact unit ready for
connection. Only establish connections for the
inlet and pressure pipe as well as the electrical
mains connection. Systems from the SiBoost
Smart 1... and COR-1... series (examples Fig. 1a to
1d and 1f to 1h) are mounted on a galvanised steel
base frame (3) with vibration absorbers (34).
Systems from series COR/T-1 (Fig. 1e) are
mounted on a plastic baseplate together with a
plastic break tank.
The supplied accessories ordered separately must
be installed.
The SiBoost Smart 1... and COR-1... systems can
be connected to the water supply network either
directly (diagram in Fig. 6a) or indirectly (diagram
in Fig. 6b). When supplied with a self-priming
pump (special version), the system may be
connected to the public water supply network
only indirectly (system separation by a non-
pressurised break tank). Information on the pump
type used can be found in the attached
installation and operating instructions for the
pump.
COR/T-1… type systems are intended for indirect
connection to the public water supply network by
means of the integrated break tank with level-
dependent replenishment and system separation
(similar to diagram in Fig. 6b).
Observe the relevant, applicable regulations and
standards when using the system for drinking
water supply and/or fire extinguishing supply.
The systems must be operated and maintained
in accordance with the relevant provisions (in
Germany according to DIN 1988 (DVGW)) so that
the operational reliability of the water supply is
permanently guaranteed and neither the public
water supply nor other consumption
installations are detrimentally affected.
The
applicable standards and directives (see Section 4
“Intended use”) on the connection and
connection type to public water supply networks
must be observed. They may be supplemented by
regulations of the water supply companies
(WVU) or the responsible fire protection
authority
. The local conditions (e.g. a supply
pressure that is too high or fluctuating
considerably and which might require the
installation of a pressure reducer) must also be
observed.
