difference between centrifugal pump and submersible pump|how submersible water pump works

Learn how a centrifugal pump works by converting mechanical energy into hydraulic energy using centrifugal force. Find out the factors affecting its performance and the .

Centrifugal pumps, also known as kinetic or roto-dynamic machines, are widely used in various industries for transferring fluids. These pumps work by exploiting centrifugal force to create a pressure difference, converting mechanical energy into hydraulic energy. On the other hand, submersible pumps are designed to be fully submerged in the fluid they are pumping, typically water. While both types of pumps serve the purpose of moving liquids, there are key differences between centrifugal pumps and submersible pumps that make them suitable for different applications.

If you’re considering purchasing a pump, you must understand the key differences between centrifugal and submersible pumps. These differences include installation location, pump functionality, and pumping capabilities. 1. Design and Construction 2. Installation Location 3. Pump Functionality 4.

Centrifugal Pump

Centrifugal pumps are versatile machines that are commonly used in industrial, commercial, and residential settings. These pumps operate by using a rotating impeller to increase the velocity of the fluid, which in turn creates a centrifugal force that pushes the fluid towards the outer edges of the pump casing. As the fluid moves through the pump, the pressure increases, allowing it to be discharged at a higher velocity.

# Centrifugal Pump Features:

- Efficient for transferring large volumes of fluid at high flow rates

- Can handle a wide range of viscosities

- Easy to install and maintain

- Suitable for applications where the pump is located above the fluid level

# Centrifugal Pump Applications:

- Water supply and distribution

- Irrigation systems

- HVAC systems

- Chemical processing

- Oil and gas industry

Submersible Pump

Submersible pumps are designed to be fully submerged in the fluid they are pumping, eliminating the need for priming and minimizing the risk of cavitation. These pumps are commonly used in applications where the pump needs to be located below the fluid level, such as in wells, boreholes, and sumps. Submersible pumps are sealed to prevent water from entering the motor, making them ideal for underwater operations.

# Submersible Pump Features:

- Self-priming and can operate with low inlet pressure

- Quieter operation compared to centrifugal pumps

- Suitable for applications where space is limited

- Can handle abrasive and corrosive fluids

# Submersible Pump Applications:

- Groundwater extraction

- Sewage and wastewater treatment

- Mining operations

- Fountain and waterfall systems

- Aquaculture

Key Differences

1. **Operating Environment**: The most significant difference between centrifugal pumps and submersible pumps is the operating environment. Centrifugal pumps are typically installed above the fluid level, while submersible pumps are designed to be submerged in the fluid they are pumping.

2. **Priming**: Centrifugal pumps require priming to remove air from the system and create a vacuum, whereas submersible pumps are self-priming and can operate with low inlet pressure.

3. **Installation**: Centrifugal pumps are easier to install and maintain as they are typically located above ground. In contrast, submersible pumps require more complex installation procedures due to their submerged nature.

Fluid of high kinetic energy is forced out of the impeller area and enters the volute. . Centrifugal pumps are used in series to overcome a larger system head loss than one pump can compensate for individually. As illustrated in Figure 13, two identical centrifugal pumps operating at the same speed with the same volumetric flow rate .
