According to Reti, the first machine that could be characterized as a centrifugal pump was a mud lifting machine which appeared as early as 1475 in a treatise by the Italian Renaissance .
Helicoid flight conveyor screws are a type of screw conveyor commonly used in various industries for the transportation of materials. These screws are known for their helicoid flighting, which is a continuous helix formed along the length of the screw. In general, helicoid screws are used in light to medium duty applications, and are preferred for their efficiency, durability, and versatility.

Helicoid Flighting Screws
Helicoid flighting screws are characterized by their continuous helix design, which provides a smooth and efficient material flow. The helicoid flighting allows for a greater volume of material to be transported compared to other types of screw conveyors. This design also helps in preventing material buildup and clogging, making helicoid flighting screws ideal for handling a wide range of materials.
Helicoid vs Sectional Screws
One of the main differences between helicoid and sectional screws lies in their flighting design. Helicoid screws have a continuous helix along the entire length of the screw, while sectional screws have individual flighting sections attached to a central shaft. Helicoid screws are known for their smoother material flow and higher capacity, while sectional screws are typically used in heavy-duty applications where higher torque is required.
Helicoid Rolling Process
The helicoid rolling process is used to create the continuous helix design of helicoid flighting screws. During this process, a flat strip of metal is rolled into a helical shape, forming the flighting of the screw conveyor. The helicoid rolling process requires precision and expertise to ensure the proper pitch and diameter of the helix, which ultimately determines the efficiency and performance of the screw conveyor.
Sectional vs Helicoid Flighting
When comparing sectional and helicoid flighting, it is important to consider the application and material being transported. Helicoid flighting offers a smoother material flow and higher capacity, making it suitable for light to medium duty applications. On the other hand, sectional flighting provides more strength and torque, making it ideal for heavy-duty applications where greater force is required to move materials.
