What is a Pump?

Pump – is an equipment used to transfer fluid from a

region of low pressure to another region at same or

higher pressure. (PSME Code 1993)

Pump – A device or machine that compresses and/or

transports fluids usually by pressure or suction, or both;

may be used to remove water from a construction site orto convey water from one elevation to another. (Harris,

C.M.; Dictionary of Architecture and Construction, 1975)

In about 120 BC someone, probably the Greek mathematician Ctesibius ,

invented the first force pump. It had 2 cylinders with single acting pistons,

connected to a single beam so that they delivered an almost continuousstream of water.

What are the different classifications

of pumps?

The different classifications of pumps are categorized as

follows:

1. As to Operating Principle

2. As to Casing Design3. As to Mounting

4. As to Connection with Driver

(Motor or Engine)

What are the Classifications of

Pumps?

Pumps are generally referred to according to their

principle of action, manner of construction or

method of operation.

Centrifugal Pump – (Built by Osborne Reynolds, 1875) A vane orimpeller rotate inside a close-fitting case, draw in liquid at the center and,

by virtue of centrifugal force, throw liquid out through an opening in the

periphery of the case.

1. The higher the speed of rotation, the greater the volume that can bepumped or the greater the head that can be generated.

2. The recommended suction lift is 4.5 meters and should not exceed 6

meters. Therefore, if the well water depth is 6 meters or less, use

centrifugal pump

3. A centrifugal pump cannot operate unless the pump casing is full of

water. For the pump to begin developing a suction at the eye of thepump, the case will have to be filled with water or “primed”.

4. Care must be taken to ensure that air is not present in the casing and

whenever possible the suction should be of the positive or “flooded” type.

What is a Submersible Pump?

Submersible

Pump – is basically acentrifugal pump

complete with electricmotors which are

positioned underwater

in a suitable bored

hole that delivers the

water to the surface.


11/48


What are the important considerations for

accurate Submersible Pump selection?

Well Diameter – indicates the size ofthe pump to be installed.

Well Depth – indicates the Static WaterLevel , the vertical distance from the surface(Datum Line) to the water level when nowater is being pump.

Pumping Water Level – the verticaldistance from the Datum Line to the waterlevel when specified capacity is beingpumped. During the pumping test, PumpingWater Level is the depth of water when theamount of water withdrawn from the well &the amount of replenishment of water to thewell is equal.

Drawdown – the vertical distance or the

difference between the Pumping WaterLevel and the Static Water Level.

Head above Datum – indicates theTotal Discharge Head (Static plus Friction)between Datum line & point ofmeasurement.

Pump Capacity – volume rate of flowexpressed in cubic meters per hour or liters

per second to be produced by the pump.

Pump Setting – the nominal verticaldistance (in meters) from Datum to thedischarge pipe connection at the pump.

Water Composition – make-up of thewater to be pumped.

Type of Drive – the specification of theavailable power source (single phase or 3phase)

Allowable Motor Overload –percentage of rated motor main plate power(in kilowatts or horsepower) that will bepermitted to be used.

Positive Displacement Pumps:

Reciprocating and Rotary

Reciprocating Pump – A pump which operates with a to and fromotion. The different types of Reciprocating Pump are:

1. Lift Pump – The simplest of the reciprocating pump and consists of apiston moving up and down in a cylinder or barrel.

A Lift Pump cannot be used to raise water above 7.50 to 8.50 meter atnormal atmospheric pressure (101 kPa) due to:

a. Loss of efficiency in the pump

b. Friction in the intake pipe

c. Impossible to obtain a perfect vacuum

2. Piston or Plunger Pump – A plunger is driven backwards &forwards, or up & down by a mechanical working head.

3. Deep – well Piston Pump – When water is more than 7.50 metersbelow the ground, it is virtually necessary to place the pump in or near thewater in the well and pump from there. Water is forced up the drop pipeand out into the delivery pipe.

What is a Diaphragm Pump?

A Diaphragm Pump is a displacement pump in which a flexible diaphragm

replaces the piston in other displacement pumps. The diaphragm is of

leather or heavy – gauge rubber. The upward movement of the diaphragm

has the same effect as the upward movement of the piston; the outlet valve

closes & the inlet valve opens & admits water. The downward movement of

the diaphragm causes the inlet valve to close & water is forced into thedischarge pipe.


18/48


What is a Rotary Pump?

A Rotary Pump is used primarily as a source of fluid power in hydraulicsystem. It continuously scoops the liquid from the pump chamber.

It is classified with respect to the impelling element as:

1. Gear Type

2. Vane Type3. Piston Type


19/48


What is a Jet Pump?

A Jet Pump is a pumpconsisting revolving impeller in the

pump housing which forces water

down a pressure line to an ejector

assembly below water level. This

ejector consists of a nozzle whichdischarges the water into a

constricted throat. This throat

leads from a suction pipe. This

arrangement permits energy of a

high pressure fluid to be converted

into a high velocity fluid.


20/48


What is a Hydraulic Ram or Ram

Pump?

Hydraulic Ram uses the energyof falling water to raise a smaller

quantity of water to greater

heights. It is a pump in which the

power generated from flowing in

an enclosed pipe is used to raisepart of the water to a height above

that from which the flow began.


21/48


What is the Pump Performance

Curve?

The characteristic curve of apump describes the factorsthat affect its performance.They are usually expressedgraphically with the rate ofdischarge (Q) as abscissa &other factors plotted asordinates, such as the Head(H), & the Net PositiveSuction Head (NPSH). Allpump manufacturers supplyperformance characteristic

curves for their pumps whichindicate how the pumpcapacity varies withdischarge pressure orsuction pressure.

Pump Selection “Rule of Thumb”: 1. If the well water depth is 6 meters or less, use Centrifugal Pump.

2. If the well water depth is 6 to 20 meters, use Jet Pump.

3. If the well water depth is more than 20 meters, use Submersible Pump or

Vertical Line Shaft Turbine Pumps.
