1. GENERAL
1.1. Applications
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).
1.2. Specifications
• Max. service pressure:
10 bar
• Temperature range:
- 15° to + 90°C
• Ambient temperature:
up to 40°C (for higher tempe-
ratures, get in touch with us)
• Suction head:
depends on NPSH of pump
Sound level
: Depend on pump size, rotation speed, working point,
motor type : it can 65 dB(A).
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 : non respect can induce injury.
Electrical security instruction : non respect can induce injury.
Security instruction : non respect can be induce
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
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.

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
).
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.
Required tools :
- Open-end wrench 13 and 19,
- Allen wrench 6,
- Screwdriver.
Bear in mind that the altitude of the place of
installation and the water temperature may
reduce the suction head of the pump
