1. GENERAL
1.1. Applications
• Circulating pumps aimed for close circuit for cooling and heating
( low T° ).
• Pumps for clear liquids in residential, agricultural, industrial, and
other applications. Drawing of water from a well, spring, river, pond,
etc. Water should not be drawn from abyssinian wells (tube, driven
well).
• Can be use in swimming pool application ( circulation and reverse
flow swimming ) and aquarium on request.
1.2. Specifications
• Max. service pressure:
• Max. suction pressure:
• Temperature range:
• Ambient temperature:
• Suction head:
• Additive:
2. SAFETY
Read this data sheet carefully before installing and starting up. Pay
special attention to the points concerning the safety of the
equipment for the intermediate or end user.
2.1. Symbols used in the manual
Security instruction : no respect can induce injury.

material damages.
3. TRANSPORT AND STORAGE
When taking delivery of the equipment, check that it has not been
damaged in transit. If anything is found wrong, take the necessary
steps with the carrier within the allowed time.
If the equipment delivered is to be installed at a
ATTENTION !
later time, store it in a dry place and protect it
from impacts and outside hazards (moisture, frost, etc.).
Handle the pump carefully so as not to alter the geometry or
alignment of the hydraulic assembly.

4.4. Accessories (optional)
• Suction kits • Isolating valves • Check valves • Foot valve-strainer
• Bladder or galvanized tanks • Anti-vibration sleeves • Motor
protection circuit-breaker • Dry-running protection • device for
On/Off control and dry-running protection • "Victaulic" coupling typ.
5. INSTALLATION
Two standard cases:
• Fig. 1: Pump in suction
• Fig. 2: Pump under pressure from storage tank (item 9) or town
water supply (item 10), with dry-running protection system.
5.1. Installation
Install the pump in a place that is easy to reach, protected from
frost, and as close as possible to the place from which water is
drawn.
Install the pump on a foundation block or directly on a smooth, level
floor.
Pump attached by two holes for 8-mm-dia. studs.
Bear in mind that the altitude of the place of
ATTENTION !
installation and the water temperature may
reduce the suction head of the pump.

5.2. Hydraulic connections
By hose with spiral reinforcement or by rigid pipe.
The diameter of the suction piping must never be less than that of
the pump.
Limit the length of the suction pipe and avoid all features that cause
losses of head (tapers, bends, etc.).
This pipe, which will slope upward 2 %, must not let in any air
(See FIG. 1).
If a rigid pipe is used, provide supports or collars so that the pump
does not bear its weight (See FIG. 1).
If the pump is in suction (See FIG. 1) : submerge the strainer (at least
20 cm), if necessary ballast the hose.
