The Banki Water Turbine Mockmoore and Merryfield. Barrel Stave … Self-priming pumps are liquid pumps designed to have the required liquid inside the cavity or pump body necessary to start the pumping process.These are self-priming centrifugal pumps with the benefits of a compact design, practical use, simple maintenance, high efficiency, and a powerful self-priming capability.The essential principle underpinning centrifugal pumpsis that they move fluids by transforming rotational energy into kinetic energy. They do this by deploying a fast-rotating impeller that provides a centrifugal force that drives the fluid outward. The fluid’s kinetic energy develops as it moves through the pump, . See more

What is an Archimedes Screw?
Archimedian Screw Pump Handbook: Fundamental Aspects of the Design and Operation of Water Pumping Installations Using Archimedian Screw Pumps Gerhard Nagel...
The Archimedes screw, also known as the Archimedean screw or screw pump, is a simple machine historically attributed to the ancient Greek mathematician and inventor, Archimedes. The screw consists of a helical surface surrounding a central cylindrical shaft, forming a spiral structure resembling a screw.
What Does Archimedes Screw Do?
The primary function of the Archimedes screw is to lift water or other fluids from a lower to a higher level. This mechanism is based on the principle of a rotating helix creating a continuous flow of liquid along its length. The design of the screw allows it to efficiently move water against gravity, making it a valuable tool in various applications.
Archimedes Screw Today
Despite its ancient origins, the Archimedes screw remains a relevant and widely used technology in the modern world. It is employed in a range of industries, including agriculture, wastewater treatment, aquaculture, and renewable energy. The simplicity and effectiveness of the screw pump make it a cost-effective solution for water transportation and irrigation systems.
Screw Pump Archimedes
The screw pump Archimedes is a type of positive displacement pump that utilizes the principle of the Archimedes screw to move fluids. This pump is particularly suitable for handling viscous liquids, slurries, and solids-laden fluids. The continuous and gentle pumping action of the screw pump makes it ideal for applications where shear-sensitive or delicate materials are involved.
Archimedes Screw Used Today
In modern times, the Archimedes screw is utilized in various industrial and environmental settings. It is commonly found in wastewater treatment plants to lift and transport sewage, sludge, and other waste materials. Additionally, the screw pump Archimedes is employed in renewable energy projects, such as hydropower generation and irrigation systems powered by water flow.
Diagram of Archimedes Screw
A typical diagram of an Archimedes screw illustrates the helical structure of the screw pump. The diagram shows the spiral blades wrapped around a central shaft, creating a continuous channel for fluid movement. The inlet, where the fluid enters the screw, and the outlet, where the fluid is discharged at a higher elevation, are also depicted in the diagram.
How Does Archimedes Screw Work?
The operation of an Archimedes screw is based on the principle of rotational motion converting into linear displacement. As the screw rotates, the helical blades scoop up the fluid at the lower end and push it upwards along the spiral path. The design of the screw ensures a continuous flow of liquid, enabling efficient lifting and transportation of water or other fluids.

Fluid enters axially through eye of the casing, is caught up in the impeller blades, and is whirled tangentially and radially outward until it leaves through all circumferential parts of the impeller into the diffuser part of the casing. . All centrifugal pumps require liquid in the liquid casing to prime. If the pump casing becomes filled .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
