A screw pump, also known as a water screw, is a positive displacement pump that utilizes one or more screws to transport liquid or fluid solids along a screw shaft. The Archimedes screw pump is a simple pump consisting of a single screw that rotates in a cylindrical chamber, moving the material along a spindle. In many low-tech applications, such as irrigation systems and agricultural machinery for moving grain and other solids, this ancient construction is still in use.

Knoll screw pumpHow it works:

Screw pump is a kind of positive displacement pump. As a result, the liquid is always removed from the space it occupies. To drive the screw pump, two counter-rotating screws are used. In this case, the rotating screws are set to rotate towards each other.

As soon as the screw pump begins to work, the driving screw is driven by the motor. It is connected to the drive shaft.

During the rotation of the drive screw, the driven screw also rotates due to the engagement between these screws. In the inlet section, a slight vacuum begins to occur due to the movement of these screws. Because of this vacuum, fluid is drawn from the inlet valve into the pump. After entering the pump, the fluid is trapped between the gaps in the "screws." As the screw rotates, the trapped fluid moves. The screw movement causes the trapped fluid volume to decrease while the fluid pressure increases.

As the fluid pressure increases to the desired pressure, it is discharged from the outlet valve and transferred to the destination.

When oil or other viscous liquid is pumped through the screw pump, the surface of the screw is lubricated, so there is little or no space between the screw as a liquid pump.

On the other hand, when pumping air/water mixtures, water, or other types of lightweight liquids, these components cannot touch each other. As a result, parts wear out faster. Therefore, it is not recommended to use a three-screw pump (in which one screw drives the other two gearless) for water supply or polyphase operation.
