This document presents a project on modifying a hand pump with a two-stage mechanical oscillation system. The project aims to reduce human effort in operating hand pumps by using a pendulum mechanism. It discusses the design of the pendulum, lever, base frame, and other components. The working principle involves using the oscillation of the pendulum to power the up and down motion of the lever, which is connected to a reciprocating water pump. The pendulum hand pump design aims to provide continuous water discharge with minimal human effort compared to conventional hand pumps.

2. INTRODUCTION
Water is one of our
basic needs.
Water pumps move
water from point a to
point b for centuries.
Modern pumps require
electricity and ancient
pumps require more
efforts to operate.
Therefore We came
with the concept of
pendulum based water

4. OBJECTIVES
To design and develop the structure
for pumping water using pendulum
principle.
To reduce human efforts.
To achieve continuous discharge of
water through pump.
To ensure safe operation of the
pump.

5. Why Pendulum operated
Piston Pump?
 Alleviation of work- For pumping the water it is
enough to move the pendulum occasionally with a
finger .
 Low Fatigue- Minimum of human strength is
required as compared to classic hand water pumps.
 Efficiency- Efficiency of pendulum operated piston
pump is greater than that of hand water pumps. (old
people and small children can easily pump out the
water.)

6. How Project works
The project explains the effect of creating the free energy
in the device made of
 Oscillating pendulum lever system.
 system for initiating and maintaining the oscillation of the
pendulum.
 system which uses the energy of the device by damping
the oscillations of the lever.
The operation of the machine is based on forced
oscillation of the pendulum, since the axis of the
pendulum affects one of the arms of the two armed lever
by a force which varies periodically. Part of the total
oscillation energy of the pendulum-lever system is
changed into a work for operating a pump, a press, a

7.  The creation of free energy was proved by a great number
of physical models. The effect of creating the free energy
is defined in this project as the difference between the
energy which is the machine transfers to the user system
by the lever and the energy which is input from the
environment in order to maintain the oscillation of the
pendulum.
 Appearance of the free energy is not in accordance with
the energy conservation law.
 The effect of creating the free energy results from the
difference between the work of the orbital damping forces
of the lever and the work of the radial damping force of the

19. PARAMETERS DECIDING THE
DISCHARGE OF THE PUMP
 Length of the pendulum
 Mass of the pendulum
 Angle of swing of the pendulum
 Displacement of the pivot
 Stiffness of the spring

etc)
 Facing (flat surface)
 Drilling
 Gas cutting (flat plate, cylindrical rods)
 Shaping
 Welding
 Tapping

21. ADVANTAGES
 The main advantage of hand water pump is to avoid
human strain.
 It also helps us for the easy way for pumping water.
 The cost required to implement this is comparatively
low.
 More efficient when compared to conventional hand
water pump as the water flow is high here.
 The pump is highly portable and has tremendous
scope in industrial usage.

22. APPLICATIONS
 Hand water pump with pendulum can be widely used
in rural areas.
 As the installation cost of hand water pump with
pendulum is low, it is useful for poor people.
 It can be installed in all the public places.
 It can be operated by children or old people as the
force required by the pump is low.

 Simply designed and developed the
structure for pumping water using pendulum
principle.
 Getting continuous flow of water through
pump.
 Pumping of water can be done safely.
 Easy for maintenance and hence less
maintenance cost.
 Children, adults as well as handicapped
people can use this pump.
