Axial flow pump is a kind of high specific speed (more than 500) pump type, characterized by large flow rate, low head, large diameter, suitable for drainage irrigation, material for cast iron, famous for cast iron large diameter drainage axial flow pump. Axial flow pump has the characteristics of large capacity and low head, widely used in low-lying river network area of large area drainage and large flow and low head water transfer project. In the professional hydropower engineering or Agricultural Water Conservancy Engineering, agricultural drainage irrigation engineering, the drainage axial flow pump according to the installation direction of the pump shaft is divided into Vertical Axial Flow Pump, Diagonal Axial Flow Pump and Horizontal Axial Flow Pump three types, the installation direction of the pump shaft is different, resulting in the hydraulic performance of the axial flow pump, installation and maintenance, engineering cost and adaptation conditions and other aspects of th...

Silicon Carbide Ceramic Lined Desulfurization Pumps The limestone-gypsum wet flue gas desulfurization technology is the most commonly used desulfurization technology in coal burning thermal power plants. Desulphurization pumps  as slurry circulating pumps are the key equipment in flue gas desulphurization unit. The slurry in FGD process has both chloride corrosion and solid particle abrasion. This kind of solid-liquid two-phase medium has a high requirement for corrosion resistance and wear resistance of a  mixed flow pump . The material used in the flow parts of desulfurization pumps can be divided into three types: the all-metal pump, the fluorine plastic lined pump, and the silicon carbide ceramic lined pump. The desulfurization pump made of metal material boast of high strength, good rigidity and plasticity. This type could choose a variety of metal materials, like carbon steel, wear-resistant cast iron, ductile iron and so on.     A Stainless Steel Desulphurizat...

  What is a seawater centrifugal pump ? What is a seawater pump? Seawater centrifugal pumps are the type of pump that mainly used for conveying seawater or salty water. Due to the high corrosion of seawater, the most ideal material for seawater pumps are duplex stainless steels including CD4MCu and S31803, Titanium alloy is also a good choice for seawater pumps if the user has a higher budget. Seawater pumps play an important role in various industrial and municipal operations situated near the ocean or other salty water applications. Centrifugal pumps, known for their reliability, efficiency, and cost-low, are commonly used for seawater applications. This article provides an overview of centrifugal seawater pumps, including their structures and working principle, general applications, model selection, maintenance and advantages compared to other type of pumps. The working principle of Centrifugal Seawater Pump The working principle of a seawater centrifugal pump is to use a rapi...
