FERI PUMPS consist of
a non-metal pumping chamber placed below the water level in
the bore. The chamber has no wearing parts. Therefore nothing
is damaged if sand or other abrasives pass through the chamber,
or if the bore is pumped dry. Because it is non-metallic, it's
also not affected by long-term submersion in heavily mineralised
bore pumping systems regularly fail due to contaminated water
causing rapid wear, or through the pump running dry in low yield
The chamber is supplied with air through
plastic piping from a surface mounted air compressor
and water is delivered through a larger plastic pipe.
The air pump, which supplies medium
pressure air, can consist of a conventional air compressor
or a diaphragm air pump driven by an electric motor, internal
combustion engine ,or wind, or Solar.
Electric motors can be either direct
current and supplied from a solar panel on site, or alternating
current (AC) supplied from the regular electricity supply.
The best news is that in the case of AC electricity supply,
the motor and air pump do not need to be located at the bore!
They can be located 5 kilometres or more away, at an existing
power supply. The air is delivered to the bore through plastic
pipe laid on the surface or underground.
Depending on the characteristics of
the particular bore, which could be deep water in a deep
bore, shallow water in a deep bore or shallow water in a
shallow bore, the water can be pumped to a storage tank located
at the bore or to a storage tank remote from the bore. Yields
of up to 13000 litres per hour are possible with No.T4
Pump. Depth to the water surface can range from zero to any
Comments by the Inventor Feri Kocsis
These pumps have been in operation successfully since 1987
all over Australia. The first DIY kit was installed in Binnu, Western
Australia in 1988 and the owners have had no need for maintenance
These pumps have many advantages. Running costs are low.
Because FERI PUMP do not lift a solid column of water, the energy
requirements are lower – saving you money every hour that you're
FERI PUMPS are very reliable. The pump chamber in the bore
is maintenance free. There is nothing in the bore to wear or corrode
even when pumping dry. The only parts to wear such as the compressor
are on the surface and easily accessible.
Extending power to a bore for a pump can be very expensive.
Huge savings can be made when installing a FERI PUMP . The air
supply can be kilometers away from your bore. You can run a cheap
air line yourself.
Due to the low energy needs of a FERI PUMP there is the
option of using solar energy or wind to drive the air pump. These
sources of energy will provide a return on your investment in a
very short period.
FERI PUMPS have been tested by the Mechanical and Materials
Engineering Department of the University of Western Australia over
a two year period. To quote Dr K Y Cheng, ‘the simplicity of operation,
the relative easy access of power source and the robustness of
the pump make it a worthwhile consideration in a range of applications.'
