Screw pumps, also known as progressive cavity pumps, are widely used in industries such as oil and gas, wastewater treatment, and food processing due to their ability to handle viscous fluids and slurries. A key component of the screw pump's functionality lies in the interaction between the stator and rotor, which together create the pumping action. This paper delves into the function of the screw pump stator and rotor, their role in fluid dynamics, and how their design impacts pump efficiency. Additionally, we will explore the importance of other critical parts, such as the rubber sleeve for screw pumps, and how they contribute to the overall performance of the pump. As we proceed, we will also highlight the relevance of universal parts in screw pumps and the role of manufacturers in providing high-quality components.
