(*) In the frequency range between 600 MHz and 1 GHz,
the display or the pressure indication in the display
might be disturbed in the direct vicinity (< 1 m from
the electronic module) of radio transmission installa-
tions, transmitters or similar devices working in this
frequency range. The functioning of the pump is at no
time affected.
5.3 Accessories
Accessories must be ordered separately.
• IF-Module PLR for connecting to PLR/interface
converter.
• IF-Module LON for connection to the LONWORKS
network. The IF Modul PLR is connected directly
inside the connection area of the converter
(Fig. 11).
• By-pass kit.
• Insulating valves.
• Bladder or galvanised tank.
• Tank for antihammer blow effect.
• Weld-on (Steel) or screw-on (Stainless Steel)
counterflange • rapid hose coupling like
"Victaulic".
• Non-return valves (with nose or spring ring when
operating in constant pressure).
• Strainer-foot valve.
• Vibrationless sleeves.
• Protection kit against dry-running
• Sensor kit for pressure regulation
(accuracy : ≤ 1 % ; use between 30 % and 100 %
of the reading range).
See catalogue for detailed list.
6. Description and function
6.1 Description of the product
The pump
• Multistage vertical pump not self-priming, with
ports in line on the same axis in bottom part.
• Shaft sealing by standardized mechanical seal.
• Hydraulic connection.
Oval flanges on the PN 16 pump casing (only for
the pump 400, 800, 1600/6): pump supplied with
oval cast iron counterflanges for screw-on tube,
rings and bolts.
Round flanges: pump delivered with rings and
bolts without counterflanges (accessories as
option).
Rapid hose coupling (only for the pump 400,
800, 1600/6) for "Victaulic" bracket: pump deliv-
ered without brackets (accessories as option).
The motor and its converter
• Cage induction motor with standardized flange
and shaft end for vertical operation fitted with
its converter.
• Motor-pump linked by a coupling with safety
guards.
6.2 Function
The basic advantages of the electronic control
are:
• Energy savings.
• Reduction of flow noises.
• Adaptation of the pump to changing operating
requirements.
The operating modes are:
• « Speed control »: setting of the frequency by
hand or external control.
• « Constant pressure » : regulation through a
pressure sensor and setting point (internal or
external).
• « P.I.D. control »: regulation through a sensor
(temperature, flow,...) by P.I.D.control and setting
point (internal or external).
7. Installation and electrical connection
CAUTION!
Danger of material damage!
Danger of damage due to inadequate handling.
The pump should only be installed by skilled per-
sonnel
.
7.1 Preparation
- The pump should only be installed when all
welding and soldering works are completed and,
if necessary flushing of the pipe system. Dirt can
cause pump failure.
- The pumps must be protected against bad
weather and in an environment protected from
some dust and from the frost, ventilated well and
in not explosive atmosphere.
- Install the pump in an easy-to-access location
so that later inspections, maintenance (e.g.
mechanical seal) or exchange is easily possible.
The air access to the dissipator of the converter
may not be limited.
