Keep the supply tank free from debris that can enter the pump; Be sure the inlet piping to the pump is the same or a larger diameter than the pump inlet; Keep the inlet piping .
On Dec 12, 2008, essential definitions for the selection and design of an Archimedean Screw Pump were outlined. Understanding key terms such as TP (Touch Point) and FP (Filling Point) are crucial in the efficient operation of this type of pump. The Archimedean Screw Pump has a long history and continues to be utilized in various applications today.
Although screw pumps have become a very common device, especially in waste water treatment (about half of Germany’s waste water plants are running with this kind of pump), there are hardly any up-to-date publications on the topic, and even in relevant seminars screw pumps are practically never dealt with.
What is an Archimedes Screw?
The Archimedes Screw, also known as the Archimedean Screw, is a simple machine traditionally used for transferring water from a low-lying body to a higher elevation. It consists of a helical surface surrounding a central shaft, forming a spiral-like structure. As the screw rotates, water is drawn up and carried along the spiral to the desired location.
What Does Archimedes Screw Do?
The primary function of the Archimedes Screw is to lift and move water or other liquids from one place to another. It is particularly effective in applications where a continuous and gentle flow of water is required, such as in irrigation systems, wastewater treatment plants, and hydroelectric power generation facilities.
Archimedes Screw Today
Despite its ancient origins, the Archimedes Screw remains a valuable tool in modern engineering and water management. Its simplicity, reliability, and energy efficiency make it a preferred choice for various industries worldwide. The design and construction of Archimedean Screw Pumps have evolved over time to meet the specific requirements of different applications.
Screw Pump Archimedes
The screw pump based on the principles of the Archimedes Screw is commonly referred to as the Archimedean Screw Pump. This type of pump is well-suited for handling fluids with high solids content or viscous materials. Its continuous and gentle pumping action minimizes shear forces, making it ideal for delicate or shear-sensitive liquids.
Archimedes Screw Used Today
In modern times, the Archimedes Screw is used in a wide range of industries, including agriculture, aquaculture, water treatment, and renewable energy. It is employed for tasks such as drainage, dewatering, conveying, and mixing. The versatility of the Archimedes Screw makes it a versatile and cost-effective solution for various pumping requirements.
Diagram of Archimedes Screw
A typical diagram of an Archimedes Screw illustrates the helical structure of the screw, the central shaft, and the surrounding casing. The diagram shows how water or liquid is lifted and transported along the spiral path as the screw rotates. Understanding the components and operation of the Archimedes Screw is essential for its proper utilization in pumping systems.
How Does Archimedes Screw Work?
The operation of the Archimedes Screw is based on the principle of displacement. As the screw rotates, the helical blades push water or liquid upwards along the spiral path. The continuous rotation of the screw creates a steady flow of liquid, allowing for efficient pumping without the need for complex mechanisms or external power sources.

As the suction lift height increases, the max flow rate and overall performance of the pump decrease. 6 ft; 7 ft; 20 ft; 25 ft; Maximum Flow Rate @ 10 Feet of Head. . Self-priming centrifugal pumps use suction lift to draw liquids from a source located below the pump's inlet. Before first use, these pumps must be primed to ensure a proper seal.
