These pumps operate while fully submerged in water.

Common uses:
• Borewells
• Sumps
• Sewage systems

Characteristics:
• Efficient at pushing water upward
• Reduced risk of cavitation

3. Positive Displacement Pumps

These pumps move a fixed amount of water per cycle.

Types include:
• Piston pumps
• Diaphragm pumps
• Gear pumps

Best for:
• High-pressure applications
• Precise flow control

4. Jet Pumps

Jet pumps use suction created by a jet of water.

Common uses:
• Shallow wells
• Domestic water systems

5. Booster Pumps

Used to increase water pressure in supply systems.

Common uses:
• High-rise buildings
• Low-pressure water networks

6. Sewage and Wastewater Pumps

Designed to handle solids and contaminated water.

Common uses:
• Municipal wastewater
• Industrial waste handling

7. Solar Water Pumps

Powered by solar energy, often used in remote locations.

Common uses:
• Agricultural irrigation
• Off-grid water supply

8. Hand Pumps

Manually operated pumps used where power is unavailable.

Key Features to Consider When Evaluating a Water Pump

1. Flow Rate

Measured in liters per minute or cubic meters per hour, flow rate determines how much water the pump can move.

2. Head or Pressure

Head represents the vertical height or pressure the pump can overcome.

3. Water Source and Quality

Clean water, muddy water, or wastewater each require different pump designs.

4. Power Source

Options include electric, diesel, petrol, solar, or manual operation.

5. Pump Efficiency

Higher efficiency reduces energy consumption and long-term operating costs.

6. Material Construction

Pump body and impeller materials affect resistance to corrosion and wear.

7. Installation Conditions

Surface mounting, submersible installation, or inline placement must match site conditions.

8. Maintenance and Service Availability

Access to spare parts and service support is important for long-term reliability.
