Submersible Pump for Borewell: Essential Considerations for Reliable Water Access

Introduction:

Access to a reliable and consistent water supply is fundamental, whether for domestic use, agricultural irrigation, or industrial applications. For properties relying on groundwater, a borewell is often the solution, and at its heart lies the submersible pump. Specifically, a submersible pump for borewell is engineered to operate efficiently while fully immersed in water, pushing water to the surface. Unlike a self priming pump or other surface pumps, submersible pumps avoid issues with suction lift and priming, making them exceptionally reliable for deep water sources. However, selecting the best submersible pump for borewell applications requires careful consideration of various factors to ensure optimal performance, longevity, and uninterrupted water access. This guide will delve into the essential considerations, helping you make an informed decision for your water needs.

Why Choose a Submersible Pump for Borewells?

The design of a submersible pump offers distinct advantages over surface-mounted pumps for borewell applications:

• No Priming Issues: Since the pump is submerged, it’s always “primed” and doesn’t require manual priming, eliminating common problems associated with suction lift. This is a key difference from a self priming water pump which, while self-priming, still operates above ground.
• High Efficiency: Water is pushed, not pulled, minimizing energy loss due to suction.
• Quiet Operation: Being underwater, the pump operates silently, a significant advantage for residential areas.
• Less Prone to Cavitation: The constant immersion reduces the risk of cavitation, which can damage the pump.
• Protection from Elements: The pump is protected from weather conditions and vandalism.

Essential Considerations When Selecting a Submersible Pump for Borewell:

To ensure you choose the right submersible pump for borewell, a thorough assessment of your specific requirements and the borewell’s characteristics is crucial.

1. Borewell Depth and Diameter:
   1. Depth: This is paramount. The pump must be rated to operate effectively at the total depth from which water needs to be lifted to the surface.
   1. Diameter: The pump’s physical size must fit comfortably within the borewell casing. Common diameters are 4-inch, 6-inch, and 8-inch, and the pump selected must match this.
2. Water Level and Drawdown:
   1. Static Water Level: The natural level of water in the borewell when no pumping occurs.
   1. Pumping Water Level (Dynamic Water Level): The level to which the water drops when the pump is actively running. The pump must be installed below this dynamic level to prevent running dry.
   1. Recharge Rate: How quickly the borewell refills after water is drawn. This determines how much water can be continuously extracted without depleting the source.
3. Water Requirements (Flow Rate & Pressure):
   1. GPM (Gallons Per Minute) or LPM (Litres Per Minute): The required flow rate. For domestic use, this depends on the number of fixtures and residents. For agricultural water pump solutions, it depends on irrigation needs.
   1. PSI (Pounds per Square Inch) or Bar: The required pressure at the delivery point. This is influenced by elevation, pipe friction, and pressure demands for appliances or irrigation systems. A good submersible water pump will provide both adequate flow and pressure.
   1. Total Dynamic Head (TDH): This is a critical calculation that combines vertical lift (from pumping water level to delivery point), friction loss in pipes, and desired pressure at the outlet. The submersible pump selected must be able to overcome this TDH.
4. Motor Power (HP) and Electrical Supply:
   1. The horsepower (HP) of the pump motor is determined by the required flow rate, pressure, and TDH.
   1. Ensure your electrical supply (single-phase or three-phase) matches the pump’s requirements. Voltage (e.g., 230V, 415V) also needs to be compatible.
5. Water Quality:
   1. Sediment/Sand Content: If the borewell water contains sand or silt, a submersible pump for dirty water specifically designed with sand-resistant impellers or a floating intake strainer is essential to prevent premature wear.
   1. Corrosive Elements: For water with high mineral content or corrosive properties, pumps made from stainless steel or other corrosion-resistant materials are recommended.
6. Materials of Construction:
   1. Look for durable materials like stainless steel for the pump housing, impellers, and shaft. These materials resist corrosion and abrasion, extending the pump’s lifespan.
7. Protection Features:
   1. Dry Run Protection: Prevents the pump from operating without water, which can cause severe damage.
   1. Overload Protection: Protects the motor from electrical overloads.
   1. Thermal Overload Protection: Shuts off the pump if the motor overheats.
8. Reliable Brands and Warranty:
   1. Choose a reputable manufacturer known for quality submersible pump systems. A good warranty provides peace of mind.
   1. Consider the availability of spare parts and service technicians.
9. Integration with Pressure Tanks and Controls:
   1. A water pressure tank (like a water tank 1000 liter or a smaller pressure tank for home) works with the submersible pump for borewell to maintain consistent water pressure and reduce pump cycling, extending its life.
   1. Pressure switches and control panels are essential for automated operation of the automatic water pump system.
   1. For an automatic self priming pump for home, the integration of these components ensures seamless water delivery. For borewells, a pressure tank for borewell is critical.

Installation and Maintenance Considerations:

• Professional Installation: Due to the complexity of wiring, sizing, and dropping the pump into the borewell, professional installation is highly recommended to ensure proper setup and prevent damage.
• Check Valve Installation: Essential for preventing water from flowing back down the well, which can cause pump damage and water hammer.
• Regular Monitoring: Periodically check water pressure, flow rate, and listen for unusual noises from the pump.
• Water Quality Testing: Regular testing of borewell water can help identify changes that might impact pump longevity.
