1. GENERAL
1.1 APPLICATIONS
The circulation pump is used to circulate liquids
in hot-water heating systems.
1.2 TECHNICAL CHARACTERISTICS
• Pumped fluids:
- Clean, non-aggressive, non-explosive and
solid-/fibre-free liquids with impurities up
to 5 mg/dm
3
.
- Maximum kinematic viscosity: 10 mm
2
/s.
Higher viscosity values can lead to incorrect
pump adjustments.
N.B.: contact us before using fluids other than
water.
• Electrical specifications: see rating plate
• Maximum operating pressure: 10 bar
• Minimum static pressure at 80°C: 0.5 bar
(0.8 bar for models 65-12 and 80-7)
• Minimum static pressure at 95°C: 1.5 bar
• Sound pressure: 50 dB(A), except models
40-9 and 40-11 which have a maximum
sound pressure of 35 dB(A).
• Temperature of liquid
- Minimum temperature: +15°C
- Maximum temperature: see table below

2. SAFETY
Please read these instructions carefully before
installation and start-up. In particular, make
sure that the points concerning the safety of
the material for intermediate or final users are
observed.
2.1 MANUAL WARNING SYMBOLS
Safety warning which can cause danger
to people if not observed.
Electricity warning which can cause dan-
ger to people if not observed.
ATTENTION
Warnings which risk
damaging the system
and causing malfunc-
tions if not observed.
2.2 SAFETY REQUIREMENTS
The outer surface of the pump may be
very hot.
When venting the air from the pump
(fig. 2), a small amount of hot water or steam
may leak.
The pumps must be electrically connect-
ed according to current law. Disconnect
the pump from the mains power supply
before moving the speed switch or working on
the terminal block.
3. TRANSPORT AND STORAGE
Make sure the material has not suffered damage
during transport upon receipt. If any damage is
found, take action against the carrier in good
time.
ATTENTION
If the delivered material
is planned to be in-
stalled at a later stage,
store it in a dry area and protect it from
impact and from the weather (humidity,
frost, etc.).
Move the pump with care so as not to alter the
shape and alignment of the hydraulic compo-
nents.
Never hang it from its power cable.
