As a representative of positive displacement pumps, screw pumps are widely used in industries such as petroleum and chemical engineering due to their compact structure, stable operation, and adaptability to complex media. They particularly excel in conveying high-viscosity fluids, particle-laden media, or shear-sensitive materials. However, in practical applications, improper selection often leads to issues such as low efficiency, increased energy consumption, and frequent failures, primarily because users focus only on basic parameters like flow rate and head while neglecting medium characteristics, operating conditions, and long-term costs. This article analyzes common selection misconceptions and provides systematic, science-based methods to help users accurately match equipment needs and enhance the overall efficiency and economy of pumping systems.

This article explains the feasibility, application scenarios, key points and precautions of vertical installation of centrifugal pumps. Vertical installation is technically feasible, suitable for space-constrained environments and deep liquid extraction. It requires attention to fixed support, pipeline connection, lubrication system and maintenance accessibility. Centrifugal pumps produced by professional enterprises can meet vertical installation needs, providing efficient solutions for industrial scenarios.

Centrifugal pumps are widely used in industrial production for their simple structure and high efficiency, but face challenges when transporting solid-containing media or slurries. This article first analyzes the characteristics of solid media and slurries, then explains the working principle of centrifugal pumps and the wear and blockage issues of traditional structures in handling solid-containing media. It compares application scenarios of various slurry pumps, clarifies that centrifugal pumps, after upgrading with wear-resistant materials and flow channel optimization, excel in transporting medium-low concentration, small-particle slurries. It also introduces their applications in municipal and mining fields and optimization solutions, emphasizing that reasonable design enables centrifugal pumps to transport solid-containing media efficiently and reliably.

In the vast industrial chain of the petrochemical industry, petrochemical pumps serve as key equipment for core fluid transportation tasks, with their global market prospects garnering significant attention. Currently, factors such as the global energy landscape, environmental requirements, and technological innovations are profoundly shaping the market trajectory of petrochemical pumps, while also presenting substantial opportunities to explore.

In the intricate system of industrial production, fluid conveying equipment is like the blood vessels of the human body, maintaining the "life" of the entire production process. The stainless steel centrifugal pump, with its outstanding performance, has become the ideal choice for numerous critical scenarios. It can not only cope with various harsh working conditions with ease but also provides a reliable foundation for enterprises' stable production and cost control.

Centrifugal pumps and multistage pumps are key fluid-conveying equipment. Single-stage centrifugal pumps transport liquids via centrifugal force from a single impeller, featuring simple structure and easy maintenance, suitable for medium-low head and large-flow scenarios. Developed from centrifugal pumps, multistage pumps achieve high head through multi-stage pressurization with multiple impellers, with more complex structure and high sealing requirements, fitting high-pressure scenarios. Each has its strengths; selection depends on head, flow and working conditions to ensure efficient conveyance.
