2. What is pump? Pump is a hydraulic machine which converts the mechanical energy into hydraulic energy. The hydraulic energy is in the form of pressure energy.

3. CLASSIFICATION OF PUMP BASED ON MECHANISM: Centrifugal Pump: The hydraulic machine which converts mechanical energy into pressure energy by means of centrifugal force is called centrifugal pump. Reciprocating Pump: In this type of pump mechanical energy converted into pressure energy by sucking the liquid into a cylinder in which a piston is reciprocating. BASED ON TYPES OF FLUID :- Water Pump: Pumps designed to move water in various applications, such as irrigation, water supply, and wastewater management. For example- Centrifugal pump, Submersible Pumps. Oil Pump : Pumps used for handling oil and other petroleum products. For example- gear pumps, screw pumps. Gas Pump : Pumps that move gases rather than liquids, often used in vacuum applications or gas transportation systems. For example- vacuum pump , blowers, Compressor Pumps etc.

4. Main parts of centrifugal pump :- Impeller:- The rotating part of a centrifugal pump is called impeller. It consists of a series of curved vanes. Casing:- It is the outer shell of pump’s components, mainly impeller. Suction Pipe:- A pipe whose one end is connected to the inlet of the pump and another end dips into water source. Delivery Pipe:- A pipe whose one end is connected to outlet of pump and another end delivers the water at a required height is known as delivery pipe.

5. Selection of Pump Fluid Type : On the basis of fluid types, we will select the pump. In case of water we will choose centrifugal pump. Flow Rate : Choose a pump that matches the required flow rate for the desired application. Fluid Viscosity and Density : In case of high viscosity fluids we will choose positive displacement pump, while in case of low viscosity fluids we will choose centrifugal pump. Pump Material : Choose materials based on fluid corrosiveness and abrasiveness (e.g., stainless steel for chemicals, cast iron for water). Energy Efficiency : Consider energy-efficient models to reduce operating costs, especially for continuous-duty pumps. Selection of pump depends on several factors:

6. Application of pumps: Oil and Gas Industry:- Use to transfer crude oil from extraction sites to refineries. Also used in oil refining processes. Power Generation :- Pumps are used to circulate water and coolants in thermal power plants. Mining and Metallurgy:- Pumps are used to transport molten metals during refining processes of metals. Automotive and Aerospace Industry : Pumps are used in vehicles and aircraft to transfer and regulate fuel. Agriculture and Irrigation : Pumps transport water from rivers, lakes, or reservoirs to fields for irrigation. Pumps are used to distribute liquid fertilizers and pesticides across large areas. INDUSTRIAL USES:

7. Advantages of Pumps : Efficient Fluid Transfer : Pumps can handle large volumes of fluids quickly and efficiently. Versatility : They can pump different types of fluids, like water, oil, chemicals, and gases. Pressure Increase : Pumps increase fluid pressure for desired work. Variety : Different types of pumps are available for different purpose. Low Maintenance : Pumps like centrifugal pumps are simple in design and require least maintenance.

8. Disadvantages of Pumps : Energy Consumption : Pumps can consume a large amount of energy, especially in industrial applications. Wear and Tear : Mechanical components can wear out over time, leading to maintenance or replacement costs. Cavitation Risks: In case of centrifugal pumps, low pressure can cause cavitation, which can damage the pump. Complexity in Operations: Some pumps need more attention and maintenance during operation due its complex design. Noise: Some pumps can be noisy during operations.

9. conclusion Pumps are essential components in moder industry and infrastructure. By understanding pump fundamentals and best practices, we can optimise performance , reduce costs, and promote innovations.
