submersible pump and centrifugal pump|pump type selection chart : private label Centrifugal pumps are widely used because they can quickly move large volumes of liquid. Unlike positive displacement pumps, which move liquid in steps, centrifugal pumps use an impeller to generate a centrifugal force that pushes liquid outward. This … See more Decanter centrifuges or solid bowl centrifuges (SBCs) are widely used in separation applications ranging from solid-liquid separation to the classification of ultrafine particles. Several models have been developed by others to describe the solid-liquid separation process in the SBC and to predict the separation efficiency (solids recovery).

During regular operation, the separated sludge collects on the decanter bowl wall. The sludge stays on the bowl wall due to the bowl rotation’s high centrifugal force. During the decanter’s shut-down, the centrifugal force is no longer present due to the absence of . See more

Design and Construction
Submersible Pump
Submersible pumps are designed to be fully submerged in the fluid they are pumping. This type of pump typically consists of a motor and pump unit that are sealed together in a waterproof casing. The motor is located at the bottom of the pump and is connected to the impeller, which is responsible for moving the fluid. Submersible pumps are often used in applications where the pump needs to be placed underwater, such as in wells, boreholes, and sewage systems.
Centrifugal Pump
Centrifugal pumps, on the other hand, are not designed to be submerged in the fluid. These pumps work by converting rotational kinetic energy into hydrodynamic energy to move the fluid. Centrifugal pumps consist of an impeller that rotates within a casing. When the impeller spins, it creates a centrifugal force that pushes the fluid towards the pump outlet. Centrifugal pumps are commonly used in industrial applications, irrigation systems, and HVAC systems.
Installation Location
Submersible Pump
As the name suggests, submersible pumps are installed underwater. This means that they are fully submerged in the fluid they are pumping. Submersible pumps are typically installed at the bottom of wells, boreholes, or sump pits. The submerged installation of these pumps helps to prevent cavitation and priming issues, making them ideal for applications where the pump needs to operate continuously underwater.
Centrifugal Pump
Centrifugal pumps are installed above the fluid level and are not designed to be submerged. These pumps are commonly placed on a base or foundation near the fluid source, with a suction pipe drawing the fluid into the pump. Centrifugal pumps are versatile in terms of installation location and can be easily mounted on a flat surface or within a piping system.
Pump Functionality
Submersible Pump
Submersible pumps are known for their high efficiency and ability to handle a wide range of fluids, including dirty water, sewage, and slurries. These pumps are designed to operate quietly and are suitable for applications where space is limited. Submersible pumps are also less prone to cavitation compared to centrifugal pumps, making them a reliable choice for continuous operation.
Centrifugal Pump
Centrifugal pumps are versatile and can handle a variety of fluids, including water, chemicals, and oil. These pumps are known for their high flow rates and are commonly used in applications where a large volume of fluid needs to be moved quickly. Centrifugal pumps are also easy to maintain and repair, making them a popular choice for industrial and commercial applications.
Operating Mechanisms
Submersible Pump
Submersible pumps operate by using the motor to drive the impeller, which creates a suction force that draws the fluid into the pump. The fluid is then pushed through the pump and discharged through the outlet. Submersible pumps are designed to be self-priming, meaning they can start pumping without the need for manual priming.
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
