Introduction:

Submersible pumps are specifically designed for underground usage and operate efficiently when fully submerged in water. These are widely used in homes, agriculture, and industries because they push water to the surface instead of pulling it.

Unlike surface, It offer better efficiency, durability, and long-term performance.

How Do You Check Wattage?

To check the wattage, look for:

• Nameplate label (HP, voltage, current)
• Control box near installation
• User manual

For underground submersible pumps, the control box usually contains this information.

Always switch off power before opening the control box.

How Do You Calculate the Wattage?

To calculate power consumption pumps:

• Daily usage hours (e.g., 0.5 hours for 30 minutes)
• Pump wattage
• Electricity rate (kWh)

Formula:
Energy Consumption = (Wattage × Hours) / 1000

This helps estimate electricity costs and optimize usage.

Benefits of Submersible Pumps

benefits:

• ✔ Low mechanical failure
• ✔ Long lifespan (20–25 years)
• ✔ No priming issues
• ✔ Cavitation-free operation
• ✔ Efficient water delivery
• ✔ Low maintenance

Functioning of Submersible Pumps

It operate underwater using an electric motor:

1. Water enters the pump
2. Impeller rotates
3. Velocity increases
4. Diffuser converts velocity into pressure
5. Water is pushed to the surface

This makes pumps ideal for deep borewell applications.

Selecting the Ideal Pumps for Your Home

Choose the right Pump based on depth:

• Up to 25 ft → Shallow pump
• 25–110 ft → Deep jet pump
• 110–400 ft → Submersible pumps

Also consider:

• Household size
• Daily water usage
• Storage capacity

---

Priming Your Pumps

Priming ensures proper functioning:

Steps:

• Turn off power
• Remove prime plug
• Fill pump with water
• Remove air
• Restart pump

---

Choosing the Right Size Pumps

Selecting the correct size depends on:

• Borewell depth
• Number of users
• Water usage patterns
• Appliance usage

Proper sizing improves efficiency and reduces energy costs.

FAQs

1. What are the advantages of a borewell motor?
Borewell motors offer high efficiency, corrosion resistance, easy installation, and versatile applications.

2. Difference between borewell and open-well submersible pumps?
Borewell pumps are used for deep wells, while open-well pumps are installed in tanks or reservoirs.

3. Which pump is suitable for 200-feet head?
A 1.5 HP submersible pump is generally recommended for agricultural use at this depth.

4. Best types of open-well pumps?
Horizontal and vertical pumps are commonly used.

5. Submersible vs centrifugal pump?
Submersible pumps are used for deep water extraction, while centrifugal pumps are ideal for irrigation and surface-level applications.

6. Are submersible pumps safe?
Yes, but avoid contact with water bodies where pumps are operating, as electricity and water can be hazardous.
