When selecting a pump, two popular options are submersible pumps and centrifugal pumps. While both are designed to move fluids, they differ in how they operate, where they are installed, and their most suitable applications. Below, we’ll explain the main differences between these two types of pumps to help you decide which one is the right choice for your specific needs.
What Is a Submersible Pump?
A submersible pump is a type of pump that operates while being fully submerged in the liquid it is designed to transport. Its motor is completely sealed to protect it from the surrounding fluid. These pumps are commonly used for underground water extraction, deep wells, and other submerged environments.
Low Noise Levels: Since the pump operates below the surface, noise is significantly reduced.
High Efficiency: Being submerged eliminates suction-related energy losses.
Common Applications: Perfect for pumping water from wells, draining flooded areas, sewage systems, and handling liquids in industrial processes.
A centrifugal pump relies on a rotating impeller to move fluids. Unlike submersible pumps, centrifugal pumps are installed above the liquid source. They use suction, powered by atmospheric pressure, to draw the fluid into the pump.
Above-Ground Installation: Positioned above the fluid level, making it easy to access and maintain.
Simple Structure: The straightforward design makes centrifugal pumps easy to operate and repair.
Versatile Usage: Commonly used in irrigation, HVAC systems, water supply networks, and industrial fluid transfer.
Lower Upfront Cost: Typically more affordable than submersible pumps.
| Aspect | Submersible Pump | Centrifugal Pump |
| Installation | Fully submerged in fluid | Installed above the fluid level |
| Operation | Functions underwater | Uses suction and atmospheric pressure |
| Noise Level | Quiet due to underwater design | Can be noisy |
| Energy Efficiency | High, with minimal suction loss | Moderate |
| Maintenance | Requires removal for servicing | Easier to maintain |
| Applications | Deep wells, drainage, sewage | Irrigation, HVAC, water supply |
