How Does Screw Pumps Work? A screw pump is a type of positive displacement pump which initiates pressure by putting axial acceleration within its clearance area to the fluid .
Centrifugal pumps are essential equipment in various industries, playing a crucial role in transferring fluids from one location to another. These pumps operate based on the principles of centrifugal force, where the rotation of an impeller imparts energy to the fluid, increasing its velocity and pressure. In this article, we will delve into the working principles of centrifugal pumps and explore various aspects such as pump sizing, impeller selection, pump selection criteria, working procedures, and the key characteristics of these versatile machines.
The Centrifugal pumpis working based on the centrifugal force and the name follows the same. Fluid enters into the pumps, gets the energy from the centrifugal force of the impeller, and raised its velocity and pressure. Due to this pressure, the liquid is transferred from one place to another. See more
Centrifugal Pump Working Principle
At the heart of a centrifugal pump lies the impeller, a rotating component that accelerates the fluid within the pump casing. As the impeller spins, it creates a centrifugal force that propels the fluid towards the outer edges of the impeller. This action increases the fluid's kinetic energy, resulting in higher velocity and pressure. The high-pressure fluid is then discharged through the pump outlet, facilitating the transfer of liquids from one point to another within a system.
Centrifugal Pump Components
# 1. Impeller
The impeller is the primary component responsible for imparting energy to the fluid. It is typically designed with curved blades that accelerate the fluid as it rotates. The size and shape of the impeller play a crucial role in determining the pump's performance characteristics.
# 2. Pump Casing
The pump casing encloses the impeller and serves to guide the flow of fluid through the pump. It is designed to minimize energy losses and maintain efficient fluid transfer within the system.
# 3. Shaft and Bearings
The shaft connects the impeller to the motor, transmitting rotational energy to the impeller. Bearings support the shaft, ensuring smooth operation and reducing friction losses.
# 4. Seal and Gland
Seals and glands prevent leakage of fluid from the pump, maintaining system integrity and efficiency.

Centrifugal Pump Working Procedure
The working procedure of a centrifugal pump involves several key steps:
1. Priming: The pump is filled with liquid to remove air and create a vacuum.
2. Start-up: The motor drives the impeller, initiating fluid flow within the pump.
3. Fluid Transfer: The impeller accelerates the fluid, increasing its pressure and velocity.
4. Discharge: The high-pressure fluid is discharged through the pump outlet, completing the transfer process.
