New and technically original idea - hand water pump with
a pendulum - provides alleviation of work, because it is enough
to move the pendulum occasionally with a little finger to pump the water,
instead of large swings. Using the minimum of human strength in
comparison to present classic hand water pumps enables efficient application
in irrigation of smaller lots, for water-wells and extinguishing fires even
by old people and children, which was proved by a large number of interested
future consumers during the presentations.
Hand water pump with a pendulum is a realisation of a new,
original, and even unbelievable, by very simple solution for pumping water.
Work is alleviated because easier, long-lasting and effortless use of the
hand water pump has been enabled. Input energy for starting the process
of pumping, in form of occasional pushing of the pendulum, is much less
than with typical hand pumps.
Hand water pump with a pendulum for pumping water out from
wells or reservoirs consists of a cylinder (1) with a piston (2), lever
system (3), a seesaw (4), a pendulum (5), a reservoir (6) and output water
pipe (7).
To get the water running out of the pump, the pendulum
needs to be out of balance. After that, based on gravitational potential,
the piston starts oscillating and the continuous stream of water is coming
out of the output pipe. The pendulum should be occasionally pushed, to maintain
the amplitude i.e. the stream of water.
The pump works well with all sizes of the pendulum, but
mainly with the amplitude of 90°.
The advantage of this invention compared to present
hand pump solutions are: less force to start the pump, less water consumption,
both arms can be used to fetch the water.
The invention is applicable on other devices that use lever
mechanisms, such as a hand press etc.

during operation of the pump.
It is possible to pump out a 1200 litres of water per
hour, without any fatigue and continue with the pumping. Both arms are free
for fetching water, and both elderly and children can use it, since maintaining
the oscillation of the pendulum does not request any special training or
dexterity.
Whereas typical hand pumps require significant effort
and an average person can use the pump continuously only for several minutes,
the hand water pump needs the minimum of the effort, because it is only
necessary to swing the pendulum and maintain the oscillation for several
hours, without any fatigue.

*Note: The pipe is placed at the depth of 12 meters,
but because of hydrostatic pressure,
water level is at the depth of 3 to 5 meters
(depending on underground waters, atmospheric rainfalls etc.)
Capacity of 1200 litres per hour is calculated by pumping the bucket of
20 litres per minute
- 20 l/min x 60 minutes = 1200 litres/hour.

strategic partners and customers for production and application.
So far, there was a lot of interest for the application of the hand water
pump with a pendulum both in domestic and foreign markets, as well as for
further development of the product.
