2. TECHNICAL DESCRIPTION
Close coupled submersible multistage pump with
integrated control, complete with integrated pressure
transducer for automatic control of starting/stopping of
the pump when utilization points are opened/closed.
For protection of the pump:
- against dry running;
- against the risk of operation without water at the inlet
(caused by a lack of water inflow in the inlet pipe
under positive suction head, by a non-immersed
suction pipe, by excessive suction lift or by air
entering the suction pipe);
External jacket in stainless steel AISI 304 and stages
Noryl.
Hydraulics are located below the motor with the motor
cooled by the pumped fluid. Safe operation is possible
with the motor only partially submerged.
Double shaft seal with interposed oil chamber.
The suction strainer prevents the ingress of solids with
diameter larger than 2mm.
2.1. Intended use
For water supply from wells, tanks or reservoirs.
For domestic use, for civil and industrial applications,
for garden use, irrigation and rain water harvesting
systems.
For clean water with a maximum temperature of 35 °C
and maximum sand content of 60 g/m3.
Minimum internal diameter of well: 140 mm.
- Minimum immersion depth: 100 mm.
- Maximum submersion depth: 12 m (with suitable
cable length).
2.2. Improper use
The device is designed and built only for the purpose
described in paragraph 2.1.
Improper use of the device is forbidden, as is
use under conditions other than those indicated
in these instructions.
Improper use of the product reduces the safety and
