Which of the following pump is successfully used for lifting water from deep wells?

🔑 Key Points
💧 Axial Flow Pumps
→ Used in applications that require very high flow rates and very low amounts of pressure or head.
→ Example applications: Water supply mains, Power plants, etc.

🌀 Centrifugal Pumps
→ Used in oil refineries and power plants.
→ Move water supply from the pressure main when little or no suction lift is required.

🔄 Rotary Pumps
→ Useful for pumping oil and other liquids of high viscosity.
→ Example applications: Refrigeration, Heating, and Air Conditioning.

🔁 Reciprocating Type Pump
→ Used when a relatively small quantity of liquid needs to be handled, and delivery pressure is large.
→ Example applications: Oil drilling operations, Pneumatic pressure systems, etc.

💨 Airlift Pumps
→ Have low suction and moderate discharge of liquid and entrained solids.
→ Often used in deep dirty wells where sand could quickly abrade mechanical parts.
