Screw pumps, also known as progressive cavity pumps, are widely used in various industries due to their ability to handle viscous fluids, slurries, and even gases with minimal pulsation. Understanding the working principle of screw pumps is crucial for optimizing their performance and ensuring long-term reliability. This post will delve into the fundamental principles behind screw pumps, supported by real-world examples and data.

When choosing a suitable pump, it is necessary to consider parameters such as liquid viscosity, flow rate, head, and self-priming ability, stability, and corrosion resistance of the pump. At the same time, you can also consult professional pump manufacturers or engineers to select according to specific working conditions and needs.

The flow range of centrifugal pumps is usually large, and the flow adjustment methods are flexible and diverse, which is suitable for large flow and high head occasions; while the flow range of positive displacement pumps is relatively small, and the flow stability is better, which is suitable for small flow and occasions that require precise flow control.

With the acceleration of global industrialization and the improvement of environmental awareness, the market demand for positive displacement screw pumps, as an important equipment for fluid transportation, continues to grow. This article aims to explore the driving factors behind the market demand for positive displacement screw pumps.
