The Differences Between Submersible and Non-submersible Pumps

In conclusion, submersible and non-submersible pumps serve different purposes and have distinct advantages and disadvantages.

Pumps are essential devices in a wide range of applications, from managing water accumulation during heavy rains to transferring fluids from one location to another.

When choosing the right pump for a specific task, one of the critical decisions is whether to opt for a submersible or non-submersible pump. Each type of pump has unique characteristics and advantages, and understanding their differences is essential for making an informed choice.  In this blog, we will dig into some key distinctions between submersible and non-submersible pumps to help you decide which one suits your needs.

Submersible Pumps

These pumps are specifically designed to operate underwater and are completely waterproof. They must be installed inside the water source they are meant to pump. Here are some common types of submersible pumps:

  • Sump Pumps: These pumps are crucial for homes with cellars or low-lying areas prone to water accumulation. During heavy rains or sewage backups, sump pumps remove excess water to prevent flooding and property damage.
  • Sewer Ejector Pumps: Installed in areas where toilets are positioned lower than the septic lines, sewer ejector pumps efficiently pump sewage waste from toilets. It’s important to note that these pumps are specifically designed for human waste and should not be used for disposing of hair, feminine products, or soap.
  • Transfer Pumps: These versatile utility pumps come in various sizes and shapes. They are employed to transfer water from one location to another, making them invaluable during emergencies like unexpected floods or draining a water heater.

Benefits of Submersible Pumps

  • Installation and Placement: These pumps are designed to submerge in the liquid they are pumping completely. They are typically installed underwater in the fluid source, such as a well, pond, or sump. This design allows them to push water directly from the source without the need for priming or external suction.
  • Sealed Design: Submersible pumps have a sealed design to prevent water or other fluids from entering the motor and electrical components. This makes them ideal for applications where the pump must operate underwater or in locations with high moisture levels.
  • Cooling Mechanism: They rely on the surrounding liquid for cooling. The fluid in which they are submerged dissipates heat, ensuring the pump remains at an optimal operating temperature. This cooling mechanism contributes to the longevity of the pump.

Common Applications:

Submersible pumps are commonly used for well water extraction, wastewater treatment, pond aeration, and deep-well drilling. They are also popular for pumping basements and sump pits in residential and commercial applications. Here is a range of submersible pumps from Jee Pumps for your industrial needs.

Non-Submersible Pumps

Non-submersible pumps, also known as surface pumps, are installed outside the water source in a dry location. They lack a waterproof seal, which means their motors should not come into contact with water. However, they are relatively easier to maintain compared to submersible pumps. Here are some common types:

  • Effluent Pumps: These pumps are designed to handle grey water, which is not sewage but also not clean water. They are commonly used to drain laundry discharge or handle sink and dishwasher drainage.
  • Pond and Other Outdoor Pumps: These pumps are crucial in managing water in ponds, pools, sprinkler systems, and livestock waste management. They come in various types: pool cover pumps, fountain pumps, and agricultural pumps.
  • Condensate Pumps: Found in air conditioning systems where condensation discharge cannot drain independently, condensate pumps efficiently remove excess condensation from the air conditioner.

Benefits of Non-Submersible Pumps:

  • Installation and Placement: They draw fluid from the source through a suction pipe and must be primed to remove air from the system before they can start pumping.
  • External Cooling: Unlike submersible pumps, non-submersible pumps rely on external cooling mechanisms, such as air cooling or water jackets, to dissipate heat generated during operation. This can make them more susceptible to overheating in certain conditions.
  • Accessibility: These pumps are easier to access and maintain since they are located above ground. This accessibility makes them a practical choice when frequent maintenance or repairs are required.

Common Applications:

Non-submersible pumps are often used in applications where the pump needs to draw water from a shallow source, such as a surface well, lake, or river. They are also employed in irrigation systems, agricultural operations, and industrial processes.

Choosing the Right Pump

The choice between a submersible and a non-submersible pump depends on various factors, including the specific application, depth of the water source, maintenance requirements, and budget constraints. Here are some considerations to keep in mind when making your decision:

  • Water Source Depth: If the water source is deep, a submersible pump is typically more efficient and practical as it can pump from greater depths without issues related to priming or suction.
  • Accessibility and Maintenance: Non-submersible pumps are easier to access for maintenance and repairs. If ease of maintenance is a priority, this might influence your choice.
  • Environmental Conditions: Consider the environmental conditions, such as the presence of corrosive substances or the risk of flooding. Submersible pumps are designed to handle harsher conditions and are better suited for submerged applications.
  • Flow Rate and Pressure Requirements: Evaluate your application’s required flow rate and pressure. Some pumps may be better suited to meet specific performance criteria.

Conclusion

In conclusion, submersible and non-submersible pumps serve different purposes and have distinct advantages and disadvantages. Submersible pumps are ideal for deep water sources and submerged applications, while non-submersible pumps are suitable for shallow water sources and situations where accessibility and maintenance ease are essential. Ultimately, the choice between the two types of pumps should be based on your specific requirements and environmental conditions.
