How Does A Submersible Well Pump Work?

Submersible Well Pump Work

Water is an essential commodity, and having an efficient system to extract it from deep within the earth is critical for both residential and industrial purposes. Submersible well pumps, a technology that has been around for many years, serve this purpose seamlessly. In this article, we’ll delve deep into understanding how a submersible well pump works. For those considering purchasing or researching more about these pumps, Linquip, a leading platform in the realm of industrial equipment, offers a plethora of resources and information on the topic.

TLDR

Submersible well pumps are devices designed to extract water from wells by being fully submerged, ensuring efficient and consistent water supply. They consist of essential components like a motor, impellers, and check valves. There are two primary types: deep and shallow well pumps. Selection should be based on well depth, flow rate, material, and brand reputation. Regular maintenance can enhance longevity. Common issues include power problems and reduced water flow, but with knowledge, they can be addressed. Technological advancements are introducing smart pumps and improved materials, enhancing efficiency. Linquip is a vital platform offering insights, updated equipment catalogs, and expert assistance on submersible well pumps, emphasizing their importance in today’s sustainable water management practices.

 

What is a Submersible Well Pump?

A submersible well pump is a device designed to be fully submerged underwater to pump and transport water from wells to the surface. Unlike jet pumps, which remain above ground, submersible pumps operate underwater, ensuring consistent and efficient water supply.

 

Main Components of a Submersible Well Pump

For a submersible pump to function effectively, it integrates several components, each serving a distinct purpose. Here’s a breakdown:

Motor

  • Purpose: Powers the pump
  • Function: It is waterproof and hermetically sealed to prevent water ingress.

Impellers

  • Purpose: To push the water upwards.
  • Function: They spin, creating centrifugal force, which propels the water.

Diffusers

  • Purpose: Direct the water flow.
  • Function: As water is pushed by the impellers, diffusers channel it towards the surface.

Check Valves

  • Purpose: To prevent backflow.
  • Function: They ensure water flows in one direction, stopping any reverse flow when the pump is turned off.

Casing

  • Purpose: To protect and house the pump.
  • Function: Typically made from stainless steel, it provides structural integrity and shields the inner components from the surrounding environment.

 

How Does It Operate?

When the pump is activated, the motor starts, which in turn drives the impellers. As the impellers spin, they draw water into the pump and push it upwards using centrifugal force. The diffusers then direct this water towards the surface. As the water rises, the check valves ensure that there is no backflow, maintaining consistent water pressure. Once the water reaches the surface, it is channeled into the desired location, be it a storage tank, residential plumbing system, or any other destination.

 

Advantages of Submersible Well Pumps

Submersible well pumps come with a plethora of benefits:

  • Efficiency: Since they are submerged, they don’t have to spend energy on suction, ensuring more efficient water extraction.
  • Longevity: Being submerged reduces wear and tear, ensuring a longer lifespan.
  • Silent Operation: Being underwater naturally dampens the noise, ensuring quiet operation.
  • No Priming Required: Unlike other pumps, submersible pumps don’t need to be primed as they are already submerged.
  • Less Risk of Contamination: Since the pump is sealed and submerged, there’s minimal risk of contaminants entering the water.

 

Types of Submersible Well Pumps

There are primarily two types of submersible pumps available in the market:

Deep Well Pump

  • Depth: Suitable for wells with a depth greater than 25 feet.
  • Design: Often has multiple-stage impellers to handle greater depths.

Shallow Well Pump

  • Depth: Ideal for wells with a depth less than 25 feet.
  • Design: Generally a single-stage pump.

 

Factors to Consider When Choosing a Submersible Well Pump

Well Depth

Determine the depth of your well to decide between a deep or shallow well pump.

Flow Rate

Consider the amount of water you’ll require in a specific time frame. The flow rate is usually measured in gallons per minute (GPM).

Power Source

Ensure you have a consistent power supply. While most pumps are electrically powered, there are solar-powered options available.

Material

Stainless steel casings are the most durable, but they can be more expensive than thermoplastic options.

Warranty and Brand Reputation

Always choose a reputable brand, and don’t overlook the importance of a good warranty. Platforms like Linquip offer insights and reviews on various brands, aiding in the decision-making process.

 

Maintenance Tips for Submersible Well Pumps

Routine maintenance can extend the life of your pump:

  • Regularly Check the Power Supply: Ensure there are no fluctuations that can damage the pump.
  • Inspect the Pump: Although it’s submerged, periodic inspection for any signs of wear and tear is crucial.
  • Monitor the Water Quality: Any changes in water quality could indicate issues with the pump or well.
  • Replace Worn-Out Parts: Regularly replace parts like seals to ensure the pump remains watertight.

Common Problems and Solutions with Submersible Well Pumps

Submersible pumps are resilient, but they aren’t immune to issues. Understanding common problems and their solutions can save time and money.

Pump Doesn’t Start or Run

  • Possible Causes: Power issues, motor damage, or faulty pressure switch.
  • Solution: Check the circuit breaker, inspect wiring, or replace the pressure switch.

Reduced Water Flow

  • Possible Causes: Clogged impellers, worn out parts, or low water levels in the well.
  • Solution: Clean the impellers, replace worn parts, or consider a deeper well or alternative water source.

Pump Runs Continuously

  • Possible Causes: Leak in the system, waterlogged pressure tank, or malfunctioning pressure switch.
  • Solution: Check and fix leaks, drain and refill the pressure tank, or replace the pressure switch.

Noisy Pump

  • Possible Causes: Damaged impellers, worn bearings, or debris in the pump.
  • Solution: Replace impellers, repair or replace bearings, or clean the pump.

 

Environmental Impacts and Sustainability

The need for sustainable water solutions has never been greater. Submersible well pumps, when used responsibly, can contribute to sustainable water usage.

  • Energy Efficiency: Modern pumps are designed to be more energy-efficient, reducing environmental impact.
  • Solar-powered Options: Some submersible pumps can be powered by solar energy, further reducing their carbon footprint.
  • Responsible Water Extraction: Over-extraction can deplete water tables. It’s vital to monitor usage and ensure sustainable extraction.
