Schroefpompen

Schroefpompen, also known as screw pumps or Archimedes screws, are a type of positive displacement pump. They are characterized by a rotating screw or series of screws that move fluid along their axis. The screw rotates within a stationary casing or a set of stationary grooves, creating sealed cavities that trap and propel the fluid from the inlet to the outlet. This design allows for a continuous flow of fluid without significant pulsation.

There are several types of screw pumps, including single-screw and twin-screw designs. Single-screw pumps typically feature a helical screw that rotates inside a double-helical stator. Twin-screw pumps have two intermeshing screws that rotate in opposite directions, with the fluid being moved between the threads of the screws. The pitch and diameter of the screws, as well as the clearances between the screws and the casing, are critical design parameters that influence the pump's performance and the types of fluids it can handle.

Schroefpompen are known for their ability to handle a wide range of fluids, including those with high viscosity, abrasive solids, and shear-sensitive materials. They are commonly used in applications such as sewage treatment, oil and gas processing, food and beverage production, and chemical handling. Their gentle pumping action makes them suitable for delicate substances that could be damaged by other pump types. Maintenance is generally straightforward, and their robust construction contributes to a long operational lifespan.
