Static head: An increase in static head (the height of the fluid above the pump’s centerline) results in higher NPSHa. In suction lift applications, care must be taken to ensure the NPSHa calculation is valid for all operating .
The Archimedes screw pump is a remarkable invention that has been utilized for centuries to efficiently move water from lower to higher levels. One notable modern application of this ingenious device can be found at Windsor Castle, where a 40-ton screw pump plays a crucial role in supplying power to the historic site.

What is an Archimedes Screw?
The Archimedes screw, also known as the Archimedean screw or screw pump, is a simple yet effective machine designed to lift water against gravity. It consists of a helical surface wrapped around a central shaft, forming a spiral that resembles a screw. When the screw is rotated, water is trapped within the spirals and pushed upwards.
What Does an Archimedes Screw Do?
The primary function of an Archimedes screw is to lift water or other fluids from a lower level to a higher level. This is achieved by the rotational motion of the screw, which creates a continuous flow of water along the helical path. The screw pump is commonly used in various applications, including irrigation, drainage, and wastewater treatment.
Archimedes Screw Today
In the modern era, the Archimedes screw continues to be a valuable tool for water management and power generation. One notable example is the implementation of screw pumps at Windsor Castle, where they play a crucial role in supplying water to turbines that convert the energy of the water into electricity.
Screw Pump Archimedes
The screw pump designed by Archimedes is a testament to the timeless ingenuity of ancient engineering. Its simple yet effective design has stood the test of time and continues to be used in various industrial and agricultural applications around the world.
Archimedes Screw Used Today
Apart from its application at Windsor Castle, the Archimedes screw is also used in modern wastewater treatment plants, aquaculture systems, and renewable energy projects. The versatility and efficiency of the screw pump make it a popular choice for moving water in a sustainable and environmentally friendly manner.
Diagram of Archimedes Screw
A typical diagram of an Archimedes screw pump shows the helical structure of the screw wrapped around a central shaft. The screw is positioned at an angle to allow water to flow upwards as it is rotated. This simple yet effective design has been replicated and adapted for various purposes over the centuries.
How Does Archimedes Screw Work?
The operation of an Archimedes screw is based on the principle of displacement. As the screw rotates, water is trapped within the spirals and pushed upwards along the helical path. The continuous motion of the screw creates a steady flow of water, allowing it to be lifted to a higher level with minimal energy input.
Windsor Castle’s power is supplied through Archimedes screw pumps. A 40-ton screw pump brings water from the Thames to two turbines that have gearboxes and generators to convert the energy of the water to …
One of the most critical factors in choosing a centrifugal pump model is the net positive suction head (NPSH) margin. Properly calculating the NPSH available (NPSHa) and maintaining sufficient margin relative to the NPSH required (NPSHr) helps prevent damaging pump cavitation and ensure a successful pumping operation.
