1. INTRODUCTION
Water, the elixir of life, is a fundamental resource that
underpins the very existence of civilization. Access to
clean and reliable water supply is a cornerstone of
public health, economic development, and
environmental sustainability (Yannopoulos et al.,
2015; Mogaji, 2016). The provision of safe and
adequate water for communities has been a
longstanding challenge, particularly in regions facing
water scarcity, inadequate infrastructure, or
burgeoning urban populations. The critical role of
water supply systems cannot be overstated, as they
serve as lifelines for society, driving progress and
well-being (Usman et al., 2019).
In the quest to address the multifaceted demands of
modern water infrastructure, the design and
fabrication of efficient and sustainable pumping
machines have emerged as a focal point of innovation
and engineering excellence. These machines are the
heart of water supply systems, enabling the
extraction, transportation, and distribution of water
from various sources to end-users. As the global
population continues to grow and the impacts of
climate change intensify, the need for reliable,
energy-efficient, and environmentally responsible
water supply solutions has become more pressing
than ever (Okhaifoh et al., 2016).
This article embarks on a journey into the realm of
the "Design and Fabrication of a Pumping Machine
for Water Supply," a realm where technology,
engineering, and environmental stewardship converge
to provide practical and sustainable solutions to the
challenges faced by communities worldwide. It
explores the intricate blend of cutting-edge
engineering, sustainability principles, and the real-
world application of pumping machines in addressing
water supply issues (Doro et al., 2020).
Our discussion delves into the critical components of
pumping machine design, emphasizing the need for
innovation and customization to cater to diverse water
supply requirements, such as municipal water

of pumping systems (Martin-Candilejo et al., 2020).
Furthermore, this article seeks to underscore the
significance of environmental consciousness in the
design and fabrication of pumping machines.
Sustainable design practices, including the use of
energy-efficient materials, renewable energy sources,
and environmentally friendly manufacturing
processes, are central to ensuring the long-term
viability of water supply systems. As we traverse the
landscape of "Design and Fabrication of a Pumping
Machine for Water Supply," we will encounter both
the challenges and the triumphs of engineers,
researchers, and innovators dedicated to securing the
future of water access. We will explore real-world
case studies, breakthrough technologies, and
collaborative efforts that are reshaping the way we
approach water supply, and we will underscore the
critical importance of sustainable design and
fabrication in this mission (Karimi et al., 2023). In the
face of mounting global water challenges, the need
for practical, innovative, and environmentally
conscious solutions has never been greater. The
discussion within this article aimed to contribute to
the ongoing dialogue surrounding water supply
technology and inspire a deeper commitment to
securing the world's most precious resource for
generations to come. The specific objectives of this
study is to develop an innovative and efficient
pumping machine for water supply that addresses the
specific challenges faced by modern water
infrastructure, taking into account factors such as
increased demand, water source variations, and
energy efficiency.
2. Materials and Methods
During the initial phase of this research endeavor,
meticulous attention was devoted to the design of the
diverse components constituting the reciprocating
pump. These essential components encompassed the
structural frame, the intricately crafted pump
chamber, the precision-engineered pump cylinder, the
robust yet agile crankshaft, and the connecting rod.
Subsequently, these components were adeptly
assembled in accordance with the schematic
illustration presented in Figure 1. This comprehensive
approach to design and assembly formed the
foundational basis upon which the subsequent stages
of this research were constructed.
Figure 1: The schematic diagram of the assembled pneumatic pumping machine
The design of this pump exhibits a working mechanism reminiscent of the treadle pump, albeit with a distinctive
characteristic - it is a hand-operated pump. This remarkable device can be aptly described as a hybrid, combining
the efficiency of the treadle pump with the convenience of a hand pump, thus offering a versatile water pumping
solution. The fundamental structure of the pump consists of two cylinders, thoughtfully positioned side by side.
To establish a seamless connection with both the suction and discharge pipes, a junction box was thoughtfully
integrated into the design. At the suction side of this junction box, a pair of check valves was strategically
affixed, serving as a protective measure to prevent water from back flowing into the water source. A mirrored
arrangement of check valves was mirrored on the discharge side of the junction box to ensure the smooth, one-
directional flow of water. Table 1, enumerates the key design parameters of this pump. These parameters
encompass the structural framework, the pump chamber, the pump cylinder, the intricately designed crankshaft,
and the connecting rod, each bearing equal significance in the functional operation of the pump. Moreover, the
table elucidates the belt arrangement employed in the design, underscoring the comprehensive nature of this
water pumping solution.

Design calculation
Pump pressure is a measure of resistance to flow. Without flow, there is no pressure.
 Design for pressure
The pressure of the pump is as expressed in Equation 1.
Pump pressure p = gh 1
Where,

the application is fundamental to selecting a material that will perform optimally. The selection of materials for
engineering and design purposes is a multifaceted process that necessitates a holistic approach. By considering a
broad spectrum of factors, including material properties, cost, environmental impact, and practicality,
professionals can make informed decisions that result in materials best suited to the task at hand while ensuring
the seamless alignment of material properties with the manufacturing process.
Components Construction Procedures
The components construction procedures are as follows:
1. Appropriate Specification
2. Build the foot valve assembly
3. Build the plunger assembly
4. Identify how much connecting pipe is needed.
 Appropriate Specification: The specification of the component parts are shown in Table 3.
Table: 3 Dimensions of the main components

Suction pipe Made of 60 mm diameter PVC pipe
Pulley arrangement
Double pulley made of mild steel; Large pulley diameter (184mm) × small pulley
diameter
 Build foot valve assembly: The purpose of the foot valve is to allow water into the cylinder without
allowing it to fall back out. (The cylinder is the lower pipe section containing the foot valve and plunder
assemblies.) It is composed of, from bottom to top:
a. 2in cap
b. 2in pipe screen with drilled holes (about 9in long)
c. 2in coupler
d. 2x3/4 reducer
e. 2x3/4 reducer with the lip filed out to allow the 3/4in pipe to slide all the way through.
f. 2in coupler
g. 3/4in pipe (about 4 in long)
h. 3/4in slip-male thread adapter
i. 3/4in brass check valve
j. 2in pipe about 36in long (not shown). It fits into coupler (f).

• Build the plunger assembly. The plunger serves two purposes. First, it provides a seal with the cylinder to
generate suction. Second, it contains a second check valve to allow water in the upper cylinder.
 3/4in threaded pipe extender. Screws into bottom of check valve (d).
 Spacers. The purpose of the spacers is to keep the gasket rigid. They should not contact the cylinder. You
can use a 2in hole saw to score a ring in each side, then use a 1-1/8in Forstner bit to bore out the inner hole.
The hole saw can be again used to finish the outer cut. These can be made from wood or plastic.
 Leather gasket. Can also be made from rubber. Carefully cut this to fit snugly in the cylinder and on the pipe
extender. When inserting the assembly in the cylinder to test the fit, first soften the leather with water.
Otherwise, you will trim it too small and need to start over.
 3/4in brass check valve
 3/4in slip-male thread adapter
 3/4in pipe 6in long with drilled holes. This allows water to enter the upper cylinder after passing through the
check valve.
 3/4x1/2in slip reducer
 Rubber stopper. Held in place by the 1/2in pipe (i). Prevents water coming up the pipe (i).
 1/2in pipe
• Identify how much connecting pipe is needed. Pipe is needed to connect the cylinder to a pump head and
the plunger to a handle at the surface. The amount of pipe depends on the depth of the static water level in
the well. From the top of the cylinder, you can reduce the pipe down to a 1-1/4in diameter pipe to save on
cost and weight. However, it does increase the force required to pull the water to the surface (hydraulic
principles). Figure 4 illustrates the front view of the pump.

From the test analysis above, the pump can safely
pump water to the average height of 4.5m under
normal operating condition.
Pneumatic systems rely on a supply of compressed
air, which must be readily available in sufficient
quantity and at the appropriate pressure to
accommodate the system's operational needs. When
integrating a pneumatic system for the first time, one
of the primary considerations revolves around
establishing a reliable source of compressed air.
The cornerstone of any compressed air supply
infrastructure is typically a reciprocating compressor.
A pneumatic system comprises several key
components, including a compressor plant, a network
of pipelines, control valves, and the essential drive
mechanisms. Within this framework, air undergoes
compression within the confines of an air compressor,
and subsequently, the compressed air flows through a
meticulously designed pipeline system to reach
pneumatic cylinders.
In the context of our discussion, this particular
construction is underpinned by a pneumatic pumping
machine. This device utilizes electrical current to
compress air, generating the force required to
transport water to a specific height. It's noteworthy
that this pump boasts the capability to function
effectively at varying water levels, accommodating
depths as profound as 325 feet in static water level,
while its motorized counterpart operates efficiently at
depths down to 225 feet.
The core specifications of this pneumatic pumping
machine are as follows: it features a 4" diameter and a
63mm cylinder, and it is tailored to fit boreholes
ranging from a minimum of 100mm to a maximumof
150mm in diameter. With a design that incorporates
two stages, it can generate a maximum pressure of
200 psi during its first stage, and it necessitates a
maximum handle effort of 106 lbs. These
specifications collectively underpin the reliable and
efficient operation of this pneumatic pumping
machine.
Operational procedure
This study introduces an innovative passive vibration
protection system that integrates principles of
vibration isolation and dynamic absorption,
effectively applied to hand-held percussion machines.
This system employs a vibration isolator positioned
between the machine's handle and casing, primarily
aimed at attenuating the high-frequency acceleration
components experienced by the operator.
Remarkably, this vibration attenuation system allows
for the use of relatively rigid isolators without
significantly increasing the overall tool mass,
resulting in a considerable reduction in hand-
transmitted vibrations. The empirical validation of
our numerical simulations is presented in this paper,
reaffirming the effectiveness of this approach.
Hand-held percussion machines are a ubiquitous
presence across a multitude of industries, including
construction, transportation, and various sectors of the
industrial landscape. These machines are favored for
their operational convenience, high efficiency, and
adaptability to a diverse range of processes.
In this study, we concentrate our analysis on the
electro-pneumatic percussion machine, a prominent
example of piston-operated impact rippers with
widespread utility in industrial and construction
domains. The underlying mechanism involves an
electric motor propelling the exciting piston through a
crank and connecting rod arrangement. This
reciprocating piston cyclically compresses and
decompresses air within the pneumatic chamber,
initiating motion in the striker. The striker
subsequently impacts an intermediate piston, which,
in turn, transfers energy to the pick, ultimately
engaging with the material under treatment.
To ensure operational control and safety, the pick
incorporates a collar preventing excessive penetration
into the machinery after each rebound against the
treatment object. Crucially, the machine necessitates
the operator to exert a continuous force, referred to as
the "feed force," by pressing the machine against the
treatment object. The feed force provides a means for
operators to regulate the machine's working process.
Consequently, a nuanced understanding of the
operator-machine interaction becomes imperative
when investigating the dynamics of hand-held
percussion machines.
Safety Precautions during Testing
1. Ensure that no loose wires are exposed,
minimizing the risk of electrical shock, and verify
that all connections are secure.
2. Prevent water from coming into contact with the
mechanical output to avoid the potential for
electrical shock or burn incidents.
3. Submerge the pump fully and securely in water,
maintaining a safe testing environment.
Maintenance Guidelines
1. Regularly clean all components to ensure proper
functionality and longevity.
2. Replace components when they show signs of
wear or damage, prioritizing equipment integrity.
3. Apply lubrication to seals as necessary to
maintain smooth operation and reduce friction.

4. Adjust the oil mist levels to meet operational
requirements and maintain efficient performance.
5. Proactively identify and address any potential air
leaks to uphold system integrity and safety.
4. Conclusion
In this study, we have successfully conducted a
comprehensive analysis, design, fabrication, and
testing of a pneumatic water pumping machine. The
outcomes of our work not only demonstrate the
viability of such endeavors but also hold promise for
the design and fabrication of compact machinery and
equipment. This, in turn, could catalyze technological
advancement and foster development within our
nation.
The integral components of this gear pump were
meticulously crafted through machining techniques.
However, it is worth noting that further exploration
and research are warranted to investigate alternative
processing methods that could enable mass
production of external gear pumps in Nigeria, thus
broadening the scope of indigenous manufacturing.
It is evident from our findings that this system
presents a practical solution, particularly in regions
with limited access to a stable electricity supply. This
system effectively harnesses minimal electricity to
draw water from the ground, offering a sustainable
water supply solution. Furthermore, the versatility of
this technology extends its applicability to the
petroleum industry.
A noteworthy advantage of this pneumatic system is
its resilience during power outages. Unlike electric
motor-driven pumps that cease operation in such
circumstances, this system can continue functioning
by utilizing the reserved compressed air stored in the
air cylinder. Notably, increasing the air pressure from
the compressor can enhance the system's flow rate,
adding to its adaptability and utility. The pneumatic
water pumping system we've explored is not only
practical but also exhibits remarkable versatility and
resilience in the face of power supply challenges. It
holds immense potential for addressing water supply
needs in areas with intermittent electricity access and
offers a promising avenue for technological
advancement and industrial development in our
country.
