1.1 History

The pump is one of civilization's earliest inventions. Considering its use in everyday life, it

may be one of the most important.

Since the beginning of time, there has been a need to push, suck or lift liquid from one place

to another. A long suspended rod with a bucket on one end and a weight on the other was

used to draw water from wells.

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical

action. Pumps can be classified into three major groups according to the method they use to

move the fluid: direct lift, displacement, and gravity pumps.

Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy

to perform mechanical work by moving the fluid. Pumps operate via many energy sources,

including manual operation, electricity, engines, or wind power, come in many sizes, from

microscopic for use in medical applications to large industrial pumps.

Mechanical pumps serve in a wide range of applications such as pumping water from wells,

aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel

injection, in the energy industry for pumping oil and natural gas or for operating cooling

towers. In the medical industry, pumps are used for biochemical processes in developing and

manufacturing medicine, and as artificial replacements for body parts, in particular the

artificial heart

Monitors and digital controls now provide more efficiency. Energy is saved through

intelligent pumping with the onset of variable speed and frequency drives. Globalization

provides more opportunities to expand the supply chain and reduce the costs of

manufacturing. A focus on engineering and design continues to strengthen the industry's

development.

All have contributed to the progression of pump technology and society's need for it.

While most of the industry's key developments did not happen in recent years, veterans in the

industry remember some of the greatest moments that helped shape the course of pump

history.

Dennis Wierzbicki, president of Grundfos Pumps Corporation, says electronic and digital

advancements have created key innovations for pump manufacturers, including, “From

providing tools to reduce quotations on large projects from weeks to hours/days, to industries

that we can serve with process equipment for production,” he says. “But most important, the

electronics age has changed the technology shift in our products, from mechanical variable

speed of the 1960s and 1970s to variable speed electronically integrated pump, motors and

drives with integration to process management systems.”

George Harris, president of Hydro, agrees. “Tools such as 3D modeling, CAD, CFD and

other powerful analysis tools enable companies to perform complex engineering analysis and

to strengthen our value-added engineering services.

“In terms of the pump aftermarket, rapid prototyping can be an important technology with

the potential to bring pump up-grades and rerates to market in a much more responsive time

frame than the traditional pattern process.”

ITT, IDP, Sterling Fluid Systems, Grundfos, Wilo and ABS have changed almost beyond

recognition. Established independent makers like Harland, Flygt, Worthington and now Weir

Pumps have disappeared, whilst newer names like Textron, Constellation Capital, IDEX,

Pentair and Flowserve have arrived on the scene, continuing the trend for the biggest

companies to get bigger.

Pump system optimization became a key ingredient in all applications.

Matt Lorenz, vice president and general manager of Eaton Corporation's Industrial Control

Division, says accurate power control has been a revolutionary development.

“At the turn of the last century, the first automatic motor starter was developed, laying the

foundation for the modern motor control industry,” Lorenz explains. “In the following years,

that technology was used to develop control equipment for the Panama Canal.” Today,

Eaton continues to provide sophisticated motor control equipment for major Panama Canal

upgrades.

Probably the biggest single change in this industry has been the transition from a local to a

global market place. Fifty years ago we had only national trade associations but today the

significant impetus in inter-company relations is at intercontinental level. The Europump

Association has grown massively in stature and effectiveness in its 49 years, and now works

in close partnership with the Hydraulic Institute in the US. This partnership reflects ever

closer cooperation between pump manufacturers' associations, a development that mirrors

this magazine's evolution from national through European to global coverage.

Pumps are used throughout society for a variety of purposes. Early applications includes the

use of the windmill or watermill to pump water. Today, the pump is used for irrigation, water

supply, gasoline supply, air conditioning systems, refrigeration (usually called a compressor),

chemical movement, sewage movement, flood control, marine services, etc.

Because of the wide variety of applications, pumps have a plethora of shapes and sizes: from

very large to very small, from handling gas to handling liquid, from high pressure to low

pressure, and from high volume to low volume.

1.2 PUMPS

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by

mechanical action. Pumps can be classified into three major groups according to the method

they use to move the fluid: direct lift, displacement, and gravity pumps.

Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy

to perform mechanical work by moving the fluid. Pumps operate via many energy sources,

including manual operation, electricity, engines, or wind power, come in many sizes, from

microscopic for use in medical applications to large industrial pumps.

Mechanical pumps serve in a wide range of applications such as pumping water from wells,

aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel

injection, in the energy industry for pumping oil and natural gas or for operating cooling

towers. In the medical industry, pumps are used for biochemical processes in developing and

manufacturing medicine, and as artificial replacements for body parts, in particular the

artificial heart and penile prosthesis.

In biology, many different types of chemical and bio-mechanical pumps have evolved, and

biomimicry is sometimes used in developing new types of mechanical pumps.

Pumps may be classified on the basis of the applications they serve, the materials from which

they are constructed, the liquids they handle, and even their orientation in space. All such

classifications, however, are limited in scope and tend to substantially overlap each other. A

more basic system of classification, the one used in this handbook, first defines the principle

by which energy is added to the fluid.

All pumps may be divided into two major categories:

Dynamic Pumps: In which energy is continuously added to increase the fluid

velocities within the machine to values greater than those occurring at the discharge so

subsequent velocity reduction within or beyond the pump produces a pressure

increase.

Displacement Pumps: In which energy is periodically added by application of force

to one or more movable boundaries of any desired number of enclosed, fluid-

containing volumes, resulting in a direct increase in pressure up to the value required

to move the fluid through valves or ports into the discharge line.

Dynamic pumps may be further subdivided into several varieties of centrifugal and other

special-effect pumps. Figure presents in outline form a summary of the significant

classifications and sub classifications within this category. Displacement pumps are

essentially divided into reciprocating and rotary types, depending on the nature of movement

of the pressure-producing members. Each of these major classifications may be further

subdivided into several specific types of commercial importance, as indicated in Figure.

Centrifugal Pumps

A centrifugal pump is of a very simple design. The two main parts of the pump are the

impeller and the diffuser. Impeller, which is the only moving part, is attached to a shaft and

driven by a motor. Impellers are generally made of bronze, polycarbonate, cast iron, stainless

steel as well as other materials. The diffuser (also called as volute) houses the impeller and

captures and directs the water off the impeller. Water enters the center (eye) of the impeller

and exits the impeller with the help of centrifugal force. As water leaves the eye of the

impeller a low-pressure area is created, causing more water to flow into the eye. Atmospheric

pressure and centrifugal force cause this to happen. Velocity is developed as the water flows

through the impeller spinning at high speed. The water velocity is collected by the diffuser

and converted to pressure by specially designed passageways that direct the flow to the

discharge of the pump, or to the next impeller should the pump have a multi-stage

configuration. The pressure (head) that a pump will develop is indirect relationship to the

impeller diameter, the number of impellers, the size of impeller eye, and shaft speed.

Capacity is determined by the exit width of the impeller. The head and capacity are the main

factors, which affect the horsepower size of the motor to be used. The more the quantity of

water to be pumped, the more energy is required.

Fig. 2

A centrifugal pump is not positive acting; it will not pump the same volume always. The

greater the depth of the water, the lesser is the flow from the pump. Also, when it pumps

against increasing pressure, the less it will pump. For these reasons it is important to select a

centrifugal pump that is designed to do a particular job.

Centrifugal pumps are a sub-class of dynamic axisymmetric work-absorbing turbo

machinery. Centrifugal pumps are used to transport fluids by the conversion of rotational

kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically

comes from an engine or electric motor. The fluid enters the pump impeller along or near to

the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or

volute chamber (casing), from where it exits.

Common uses include water, sewage, petroleum and petrochemical pumping. The reverse

function of the centrifugal pump is a water turbine converting potential energy of water

pressure into mechanical rotational energy.

A centrifugal pump converts mechanical energy from a motor to energy of a moving fluid. A

portion of the energy goes into kinetic energy of the fluid motion, and some into potential

energy, represented by fluid pressure (Hydraulic head) or by lifting the fluid, against gravity,

to a higher altitude.

Principles of Centrifugal Pump

Submersible pumps are multi stage centrifugal pumps. The two main components of a

centrifugal pump are the impeller and the diffuser. The Impeller takes the power from the

rotating shaft and accelerates the fluid. The diffuser transforms the high fluid velocity

(kinetic energy) into pressure.

1.3 Market Analysis

Global pump demand will rise 6.4 percent yearly through 2016 to $76.1 billion. Gains in

developing areas such as China and India will result from investment in water infrastructure

and electricity generation. In developed areas, growth will be driven by process

manufacturing. Positive displacement and centrifugal pumps will lead gains.

This study analyzes the $55.8 billion world pump industry. It presents historical demand data

for the years 2001, 2006 and 2011, and forecasts for 2016 and 2021 by product type (e.g.,

centrifugal, rotary positive displacement, reciprocating positive displacement, oilfield,

turbine), market (e.g., process manufacturers, water infrastructure, oil and gas), world region

and for 36 major countries.

The study also considers market environment factors, details industry structure, evaluates

company market share and profiles 37 industry participants such as Grundfos, Flowserve,

and Xylem.

Literature Review

Khin Cho Thin, Mya Mya Khaing, and Khin Maung Aye:In this research paper they showed

different values of losses by varying Q and H. In centrifugal pump the power is generated

inside the centrifugal pump and pressure head is depend on flow rate of pump. In order to get

Characteristic curve of centrifugal pump, theoretical values like head, slip, shock losses,

friction losses are calculated by varying Flow rate.

Pump is used in general purpose too because

Lower cost

Higher efficiency

Uniform and continuous discharge

Easier installation and maintenance

The performance analysis also done in this research paper. The impeller friction losses,

volute friction losses and disk friction losses are considered to be less then friction effect on

centrifugal pump.

Greg case and William D. Marscher: This research paper provides information about

choosing machinery for centrifugal pump.

We should check machinery before installation and if it is possible check it before

purchase. If you can’t able to check it properly hire specialist to check machinery.

There are lots of thing which can be checked by non-specialist or you can do by

yourself.

You must be careful about size of pump. You should not buy oversized pump because

it increase part load and Due to this it increases time spent for pumping process.

You must be careful while assessing and controlling pipe loads. Expansion joints may

relive at some point in thermal expansion but it results into higher hydraulic thrust

making situation worse.

Use of Computerized tools in case of rotordynamics, alignment monitoring, and

natural frequency testing is better than manual techniques.

Abdulkadir Aman, Sileshi Kore and Edessa Dribssa: In this research paper CFD analysis of 2-

D model of backward curved six bladed centrifugal pump is Done. Here pressure and

velocity distribution in flow passage is shown. And also pump characteristics calculated with

the help of fluent numerical results.

11

In this paper experimental results are not available but theoretical results are agree with

other author’s practical work for similar pump. According to this paper there is small area of

low pressure at suction side of blade inlet and flow increases as the area is close to middle of

blade suction side. Static pressure also increases on diffusion section of volute with increase

in small flow rate but Static pressure decreases at other parts with higher flow rate.

The simulation results of flow rate and pressure head are also compared with theoretical

values and It also agree with flow rate and it also shows accuracy of analysis.

From the analysis, it is concluded that pattern of centrifugal pump is described by Moving

reference frame (MRF) and the k-ε turbulence model. And valuable information about pump

is derived by numerical results of FLUENT analysis.

S.Rajendran and Dr.K.Purushothaman: In this paper a 3D model of centrifugal pump is

made by using computational fluid dynamics, flow pattern through pump, performance

results and circumferential area. Stream wise variation of area averaged absolute velocity and

variation of mass averaged total pressure contours at blade leading edge and trailing edge for

designed flow rate are presented. The CFD predicted head according to flow rate is

approximately H=9.452 m. The pressure contours displays a continuous rise from leading

edge to trailing edge of impeller because of dynamic head produced by rotating pump

impeller. At leading edge of blade low pressure and high velocities occurred due to low

thickness of blade. At trailing edge of blade total loss can be observed because of trailing

edge wake.

Lamloumi Hedi, Kanfoudi Hatem, Zgolli Ridha:In this paper , the internal flow or velocity

vector is very smooth along the curvature along the blades but flow separation occurred at

leading edge because of nontangential inflow conditions. There are two kind of flow

structures are observed in this paper.

Single vertical flow

Double vertical flow

While operating on off-design load condition, the flow pattern varying significantly from

design load condition. There is strong flow recirculation at centre of passage of impeller. The

stall region developed due to the recirculation is blocking the flow passing through the

passage. In this case, the rotational effect is also an important factor to be considered

Project Title: Design and performance analysis of a radial flow

centrifugal pump

This project deals with the design and performance analysis of a pump. Pump is analyzed by

using a single-stage end suction centrifugal pump. Two main components of a centrifugal

pump are the impeller and the casing. The impeller is a rotating component and the casing is

a stationary component.

In centrifugal pump, water enters axially through the impeller eyes and water exits radially.

The pump casing is to guide the liquid to the impeller, converts into pressure the high

velocity kinetic energy of the flow from the impeller discharge and leads liquid away of the

energy having imparted to the liquid comes from the volute casing.

A design of centrifugal pump is carried out and analyzed to get the best performance point.

The design and performance analysis of centrifugal pump are chosen because it is the most

useful mechanical rotodynamic machine in fluid works which widely used in domestic,

irrigation, industry, large plants and river water pumping system.

4.2 Non – Dimensional Analysis

CENTRIFUGAL PUMP CONSTANTS FROM GENERAL PRINCIPLES OF

SIMILITUDE

Dimensional analysis applied to problems of similitude in hydraulics proved to be a useful

tool in many instances. It disclosed the functional relationship among the quantities involved

and established dimensionless criteria of flow, found already experimentally in many cases,

for conditions known as dynamically similar. One of the important contributions of

dimensional analysis to our knowledge of model testing is that it indicated the limitations of

the theory of similitude, showed the way to evaluate the various factors affecting the flow,

and, sometimes, by destroying the geometrical similarity, indicated how to obtain the desired

information from model testing. Applied to centrifugal pumps, the dimensional analysis did

not contribute anything new, but it established from the very general principle the constants

in a dimensionless from and facilitated, from experience with water, the drawing of

conclusions regarding the behavior of pumps when pumping liquids of different viscosities.

The affinity laws follow from these constants.

Use will be made of the method of procedure proposed by Buckingham. The principle of

dimensional analysis requires that all the terms of a correct and complete physical physical

equation shall have the same dimensions. This implies that the object to be studied by

dimensional analysis should be known well enough to permit assumption of the physical

quantities expected to affect the phenomenon under consideration.

In the case of centrifugal pumps the quantities involved are

H pump head (length) l

Q capacity (volume per unit time) l3/t

N speed in revolutions per minute (number per unit time) 1/t

D impeller diameter representing the pump size for a series of similar pumps l

g acceleration due to gravity, constant l/t3

liquid density (mass per unit volume) m/l3

19

μ absolute viscosity (viscosity coefficient) m/lt

E energy applied (to the shaft) and obtained in the form of pump output measured in foot-

pounds or H×mg, or per unit mass E=gH which differs from the head by a constant g ; its

dimension is l2/t

2

Energy per unit mass E= gH will be used instead of head because of its more general

character and because it includes the effect of the acceleration due to gravity. It should be

remembered that all equations for the head developed by an impeller are based on the law of

conversation of energy which, for an incompressible fluid with a constant acceleration due to

gravity, reduces to the height the liquid can be raised by the pump. Thus the number of

quantities necessary to describe the operation of a centrifugal pump reduces to six: Q, E, N,

D, ρ and μ. These are measured by three fundamental units: length (l), time (t), and mass (m).

The relation among these quantities may be expressed by a general functional equation

f (Q, E, N, D, ρ, μ) = 0

According to a theorem of dimensional analysis a complete equation describing the relation

among n different quantities measured with k fundamental units that can be reduced to the

form

In this case three fundamental units so,

f ( = 0

where π represents a dimensionless product of the form

π =

where a, b, c, d, e, f, g are whole no. or functions or equal to zero in which case the

corresponding factor is equal to unity ; f if some unknown function to be found by

experiment. If we select E, D, ρ as three independents, the dimensionless quantities

can be put in the form

Where, etc. ate the unknown exponents to be determined

To do this, express Q, E, N, D, ρ, μ in terms of their dimensionless equations.

20

To make dimensionless the exponents of l, t, and m must be equal to zero

For we obtain the three equations in terms of all the corresponding values so, we

can get

=

=

=

Where v is kinematic viscosity = μ / ρ

According to dimensional analysis, the relationship between can be established

only experimentally, The π products remain constant for similar impellers and dynamically

similar conditions, irrespective of the rotative speed or size of the impellers ; they are criteria

of the flow.

For practical purposes these expressions will be transformed by making use of the fact that if

any of the π functions are constant for similar impeller their products or any power, also will

remain constant and also will be criteria of operation of the impeller. Thus,

=Q/vD

=N /

=Q/N

=gH/

An infinite no. of dimensionless criteria can be obtained in a similar manner, but only three

of them will be independent.

a) Reynolds Number :

The expression =Q/vD= (Q/D) is a form of Reynolds no. , in which

diameter D represents the size of the machine and Q/ the velocity, as for similar pumps

Q/ is proporsional to the velocities at the corresponding point of channels comprising

impeller and casing of the pump.

b) Specific speed :

21

The expression =N / is a dimensionless expression for specific speed . To

be dimensionless all terms have to be expressed in fundamental units.

c) Specific capacity :

The expression =Q/N is called specific capacity. The physical meaning of the

specific capacity is volume per 1 rps with an impeller of 1-ft diameter. The specific capacity

remains constant for all similar impellers.

d) Specific head and head co-efficient :

Equation =gH/ is a dimensionless expression for head and may be termed

as “specific head”.

And the head co-efficient φ= =

Conclusion

Conclusion:

The design of centrifugal radial flow submersible pump’s impeller and diffuser were done by

mathematical and theoretical modeling. In this exercise, we conclude that,

Actual head of 10-stage tested pump is 45 m, and flow rate is 0.000277 .

While theoretical value of head of single stage is 4.5125m by using slip factor, co-

efficient of head, co-efficient of flow, co-efficient of speed.

According above values, there is variation between theoretical and actual rated values of

head of pump, because of various losses of flow such as pressure distribution, velocity

distribution and pump vorticity etc.

The domain of losses we will examine by performing flow analysis with the help of ANSYS

CFD tool.
