Part-B-Micro-Project Report
Title of Micro Project:
“Study and prepare report on Submersible Pump”

Introduction:

A submersible pump is a centrifugal pump (Figure1), which is attached to an electric motor and oper- ates
while submerged in water. The sealed electric motor spins a series of impellers (Figure 2). Each impeller in
the series forces water through a diffuser into the eye of the one above it. In a typical 4 inch submersible
pump, each impeller will add a approximately 9 psi of pressure. for example, a typ-ical 10-stage pump will
develop a pressure of about 90 psi at its outlet (i.e.10 impellers x 9 psi).

The capacity of the pump is determined by the width of the impeller vanes andits pressure by the number
of impellers. As an example, a 1/2 horsepower 7-stage pump may deliver a high volume of water at a low
pressure while a 1/2 horsepower 14-stage pump will deliver a lower volume but at a greater pressure. Like
all other centrifugal pumps, an increase in well depth or discharge pressure will reduce the capacity.

3.0 Installation :
A typical installation for a submersible pump, pressure tank and fittings is shown in Figure 3.Prior to well
installation, the pump should be wired, submerged in a container of water and operated. The size and
type of drop pipe used for a submersible installation depends on the following:

1. Depth to the water and pumping level.

2. Pressure that the pump can develop.
3. Allowable friction loss in the drop pipe.
4. Weight of the pump.
When making male adaptor connections for the drop pipe, use only nylon (with three serrations),bronze or
galvanized (with seven serrations). The pipe should be warmed with hot water (less than 65°C) before
making a connection. Never use a torch to heat plastic pipe as it can crystallize the polyethylene. All
connections must be double clamped with 100 per cent stainless steel clamps, and the screw heads should
face opposite directions. A nylon safety rope is recommended, and it should be tied using a bowline knot.
After installation, the rope should be
tightened and tied at the top of the well casing to re-duce the free fall distance in case of a pitless unit or pipe
failure. The electrical cable to the pump can be inserted into a 3/4 inch plastic pipe to protect it from rubbing
against the side of the well casing. Submersible pumps should be protectedfrom power surges or lightning
strikes. Pumps with 1 horsepower motors or less often have built- in protection, but this condition should
be verified with the supplier and manufacturer’s specifica-tions. Alternatively, a lightning arrestor may be
required to protect the pump.
 4.0 Start-up :
Before starting the pump, close the restrictor valve almost completely. Start the pump
and gradually open the restrictor valve until the pump is either (a) pumping at full well
yield, (b) pumping at rated capacity, or (c) begins pumping sandy water. In the last
situation, submersiblepumps will wear out very quickly if they pump water containing
sand. In some situations, restricting the pump using the restrictor valve will be all that is
necessary to prevent sand from being lifted up the well casing and into the pump. The
pump should never be shut off while pumping sandy water. The pump should be
restricted until the water comes clear.

5.0 Limitations :
The tolerances between the impellers and diffusers are relatively small; therefore,
submersible pumps are unsuitable for pumping water that contains sand or other
abrasives. Submersible pumpsare water cooled and water lubricated. They should not be
installed in wells that will pump dry, unless they are protected by a liquid level control.
Types Of Submersible Pumps :

1. Borewell Submersible Pumps 2. Oil-filled Submersible Pumps

3. Water-filled Submersible Pumps 4. Stainless Steel Submersible Pumps

5. Horizontal Openwell Submersible Pumps 6. Deep Well Submersible Pumps

7.Openwell Submersible Pumps 8. Dry-Type Openwell Submersible Pumps

 7.0 Advantages :
1. High Efficiency : Submersible pumps are more efficient compared to traditional
pumps because they push water instead of pulling it. This reduces energy consumption
and operatingcosts.
2. Less Space Required : Since submersible pumps are installed underwater, they
save spacecompared to above-ground pumps, making them ideal for small or cramped
areas.
3. Low maintenance Cost : Submersible pumps are typically sealed and do not
require muchmaintenance. They are also less susceptible to damage from weather and
debris since they aresubmerged.
4. Quiet operation : Being underwater dampens the noise generated by submersible
pumps,making them quieter compared to above-ground pumps.
5. No priming required : Submersible pumps are self-priming, meaning they do not
requirepriming before operation, which simplifies installation and operation.
6. No cavitation occure : Since submersible pumps are submerged in the fluid they are
pumping,they prevent cavitation, which can occur in above-ground pumps when there's a
significant difference in elevation between the pump and the fluid level.
7. Safety : Submersible pumps are safer because they are installed underwater, reducing
the riskof electrical hazards and accidents.

8.0 Disadvantages :
1. Initial cost : Submersible pumps can have a higher initial cost compared to traditional
above-ground pumps. This can include the cost of the pump itself as well as installation
expenses.
2. Complex installation : Installing submersible pumps can be more complex than
installingabove-ground pumps, especially in deep wells or underground reservoirs. It
may require specialized equipment and expertise.
3. Potential for corrosion : Submersible pumps are constantly submerged in water, which
can lead to corrosion over time, especially in environments with high levels of salt or other
corrosivesubstances.
4. Difficult to access for maintenance : While submersible pumps typically require less
maintenance, accessing them for repairs or maintenance can be more challenging since
they arelocated underwater. Specialized equipment or personnel may be needed.
5. Limited to specific application : While versatile, submersible pumps may not be suitable
forall applications. For example, they may not be ideal for pumping extremely abrasive or
viscous fluids.
9.0 Applications :

1. Water supply : Submersible pumps are commonly used for supplying water from
wells,boreholes, or reservoirs for residential, agricultural, and industrial purposes.
Sewage and wastewater treatment : Submersible pumps are widely used in sewage
and wastewater treatment plants to pump sewage, sludge, and other wastewater
materials.
2. Drainage : They are utilized for draining flooded areas such as basements,
construction sites,and underground parking lots, as well as for controlling groundwater
levels in excavation sites.
3. Mining : Submersible pumps are employed in mining operations for dewatering
undergroundmines, transporting abrasive slurry, and removing water from mine shafts.
4. Aquaculture : They are used in aquaculture farms for circulating water, aerating
ponds, andpumping water in fish tanks and breeding facilities.
5. Industrial applications : Submersible pumps are utilized in various industrial
processes suchas chemical processing, oil and gas production, and manufacturing for fluid
transfer, circulation, and cooling.

6. Fountains and decorative water features : Submersible pumps are used in

decorative water features, ponds, and fountains for circulating and aerating water,
creating visually appealing displays.
7. Geothermal heating and cooling : They play a role in geothermal heating and
cooling systems by circulating water through underground loops to transfer heat to or
from the ground.
8. Marine applications : Submersible pumps are used in marine environments
for bilge pumping, ballast pumping, and transferring water onboard ships and
offshore platforms.
9.Firefighting : They are utilized in firefighting operations for pumping water from
naturalwater sources such as lakes, rivers, and reservoirs to extinguish fires in remote
or inaccessibleareas.

10.0 MICRO-PROJECT REPORT:

Submersible pumps are essential equipment used in various industries and applications for
pumping fluids from underground reservoirs or bodies of water. This report provides an
overview of submersible pumps, including their operation, applications, advantages, and
considerations.
Submersible pumps operate by being submerged in the fluid they are tasked to pump. They
consist of a motor, impeller, and housing encased in a waterproof enclosure. The motor
drives theimpeller, which creates suction, drawing fluid into the pump and then pushing it
to the surface or desired location.
