From delivery to exploitation,
the technical features:
Leaving the factory, each model comprises the following standard items:
- A wheel equipped with a drive head with15 blades of
galvanized sheet metal. Their specially adapted
curvature, studied in wind tunnel tests, ensures that the
windmill operates even at very low wind speeds of less
than 3 m/s. The rotating motion of the wheel is converted
into vertical reciprocating motion on the windmill head
by means of a crank and connecting rod system. This
motion is transmitted to the pump piston by the linkage
bolted onto the bearing neck at the base of the
- A tower made up of steel angles treated with a coat of
rustproof paint or by hot galvanizing to ensure very long-term
- A suction and discharge piston pump (range of pump
starting from a 40 mm diameter) comprising a cylinder, a
piston, two flanges and rods.
Note : The materials used (as stainless
steel, brass and bronze) must be selected according to the water
- A rudder to keep the wheel facing into the wind and a
feathering blade. This assembly is articulated (patented
system) so as to ensure that the windmill is set to
safety mode in case of gusts with a wind speed of more
than 9 m/s or storms. In these circumstances, the
windmill's rotational speed should not exceed 80 rpm.
- Pumping accessories: a strainer, a bleed valve to be
fitted on the piping in order to avoid problems with
freezing. Plus the equipment specific to each
installation: straight junctions, elbow, outlet tee
- This operation can be carried out by the customer himself
with the help of an explanatory manual (one day's work
for two people). Our technicians are ready to give advice
by telephone at all times.
- A network of approved independent installers is also at
your disposal. (Please consult us for details and
It is essential to comply with maintenance recommendations in
order to ensure the correct operation and long service life of
these machines. Maintenance is carried out with the windmill
stopped and consists of just the two following operations:
- greasing of bearings (once or twice a year).
- bleeding of piping in case of freezing conditions. .
The patented ground stop device has been designed to
facilitate maintenance work . This device, supplied as optional
equipment, is strongly recommended. Futher more, it can be used
as an easy means of preventing problems due to freezing and
drying-out of the well.
Note : a stuffing box can be installed in the well to
allow pumping to be continued during the winter without any
problems with freezing (look at the information scheme)
Our machines are covered by a one-year
guarantee for use in normal conditions and good
