difference between submersible pump and centrifugal pump|goulds centrifugal pump catalogue : companies
When selecting a centrifugal pump, one should match the performance of the pump to that needed by the system. To do that, an engineer would refer to a pumps composite curve. A typical composite curve includes the pump performance curves, horsepower curves and NPSH required. A pump performance curve indicates how a pump will perform in regards .Centrifugal Pump curves show 8 important factors that are critical in selecting the right pump for your application. These factors are: Flow, Head, Impeller Trim Diameter, Efficiency, Power, NPSHR, MCSF (Minimum Continuous Stable Flow) and RPM.

Depending on Various parameters, centrifugal pumps can be grouped into the following types: The fluid enters through the pump suction nozzle (Fig. 5) at the center of the impeller. .
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. Let’s delve deeper into the variances between these two types of pumps.

Design and Construction
**Submersible Pump:**
A submersible pump is designed to be submerged in the fluid it is pumping, typically water or other liquids. This type of pump is sealed to prevent water from entering the motor and other components. The motor is usually located at the bottom of the pump and is designed to operate underwater without any issues.
**Centrifugal Pump:**
Centrifugal pumps are not designed to be submerged in the fluid being pumped. These pumps use an impeller to create centrifugal force, which moves the fluid through the pump and out into the system. Centrifugal pumps are typically used for applications where the pump needs to be above the fluid level.
Installation Location
**Submersible Pump:**
Submersible pumps are installed underwater, either in a well, tank, or other water source. These pumps are fully submerged in the fluid they are pumping, which helps to push the fluid to the surface with greater efficiency. Submersible pumps are commonly used in deep well applications.
**Centrifugal Pump:**
Centrifugal pumps are installed above the fluid level and are typically used for applications where the pump needs to be mounted on a base or platform. These pumps are not designed to be submerged and rely on gravity to move the fluid through the system. Centrifugal pumps are commonly used in industrial and commercial applications.
Pump Functionality
**Submersible Pump:**
Submersible pumps are known for their efficiency and ability to pump water from great depths. These pumps are often used in residential, agricultural, and municipal applications where a high volume of water needs to be pumped over a long distance. Submersible pumps are also known for their quiet operation and low maintenance requirements.
**Centrifugal Pump:**
Centrifugal pumps, also known as kinetic or roto-dynamic machines. By exploiting centrifugal force, these pumps create a pressure difference to convert mechanical energy into hydraulic
Impeller and displacement pumps try to move the same amount of water continuously and work harder if the discharge is restricted until something fails or they are switched off. Centrifugal pumps on the other hand move less .
