A progressive cavity screw pump, commonly known as a progressive cavity pump is a type of positive displacement pump distinguished by its ability to handle highly viscous, abrasive, or shear-sensitive fluids. It comprises a helical rotor and a flexible stator, which together form a series of cavities that move fluid smoothly from the inlet to the outlet. This design allows for a constant flow rate irrespective of pressure changes, ensuring efficient and non-pulsating fluid delivery. Progressive cavity pumps are versatile, capable of handling a range of fluid types, including thick slurries, shear-sensitive substances, and abrasive materials, making them ideal for industries such as oil and gas, food processing, and wastewater treatment. While they offer high efficiency and versatility, they do require regular maintenance to manage wear and tear, particularly on the stator, which is prone to degradation when dealing with abrasive substances. Overall, these pumps are valued for their reliability and ability to maintain steady flow under challenging conditions.
