The Archimedes screw has had a resurgence in recent years because of its proven trouble-free operation and efficiency in pumping water. This ancient technology, attributed to the Greek mathematician and inventor Archimedes, has been adapted and modernized for various applications, including water pumping systems. In this article, we will explore the design, function, and benefits of the Archimedean screw water pump.

What is an Archimedes Screw?
An Archimedes screw is a simple machine used for lifting water or other fluids. It consists of a helical screw blade, known as a flight, that is wrapped around a central shaft. As the screw rotates, it scoops up water at the lower end and carries it to the top, where it is discharged. The design of the screw allows it to lift water vertically, making it an effective tool for irrigation, drainage, and water supply systems.
What Does Archimedes Screw Do?
The primary function of an Archimedes screw is to lift and move water from a lower to a higher elevation. This is achieved through the rotational motion of the screw, which creates a continuous flow of water along its length. The screw can be used in various applications, such as draining flooded areas, irrigating fields, or supplying water to industrial processes. It is a versatile and efficient tool for water management.
Archimedes Screw Today
Today, the Archimedes screw is still widely used in water pumping systems around the world. Its simple design and reliable operation make it a popular choice for applications where a continuous and consistent flow of water is required. Modern advancements in materials and manufacturing techniques have allowed for the construction of larger and more efficient Archimedes screws, capable of handling high volumes of water with minimal maintenance.
Screw Pump Archimedes
The screw pump Archimedes is a type of pump that utilizes the principles of the Archimedes screw to move fluids. It consists of a rotating screw inside a cylindrical casing, similar to the traditional Archimedes screw design. As the screw turns, it pushes the fluid towards the outlet, providing a steady flow of water or other liquids. Screw pump Archimedes are commonly used in wastewater treatment plants, aquaculture systems, and industrial processes.
Archimedes Screw Used Today
The Archimedes screw is used in a wide range of applications today, from small-scale irrigation systems to large-scale water treatment plants. Its versatility and reliability make it a popular choice for pumping water in various industries, including agriculture, aquaculture, and wastewater management. The screw can be customized to suit specific requirements, such as varying flow rates, head heights, and fluid viscosities.

How Does Archimedes Screw Work?
The operation of an Archimedes screw is based on the principle of displacement. As the screw rotates, the helical flight scoops up water at the lower end and carries it upwards. The pitch of the screw determines the amount of water lifted per rotation, while the speed of rotation controls the flow rate. The design of the screw ensures a continuous and efficient movement of water, making it an ideal choice for pumping applications.

Roller pros are that it is easier to flow at low flows (centrifugal pumps have back flow if RPMs are not high enough), and allow you to fully stop arterial flow without clamping. Roller cons: preload and after load independent. Meaning that if the preload, or venous return is cut off, it will continue pumping and will just pump air to the patient.
