Product Introduction
A double suction pump, also known as a split - case pump, is a type of centrifugal pump widely used in various industrial and municipal applications.
Working Principle
It operates based on the principle of centrifugal force. The impeller of the double suction pump rotates at high speed, creating a low - pressure area at the center. This causes the fluid to be drawn into the pump from both sides simultaneously through the suction inlet. As the fluid moves through the rotating impeller, it gains kinetic energy and is then discharged at a higher pressure through the discharge outlet.
Structural Features
Symmetrical Design: The most prominent feature is its symmetrical double - suction impeller. This design allows the fluid to enter the impeller from both sides, effectively balancing the axial thrust generated during operation. As a result, the pump experiences less wear on the bearings and shaft, leading to a longer service life and more stable operation. Split - Case Construction: The pump casing is typically split horizontally or vertically. This split - case design simplifies maintenance and inspection. When maintenance is required, the upper part of the casing can be easily removed, providing convenient access to the internal components such as the impeller, shaft, and seals without disturbing the piping connections.
Performance Advantages
High Flow Rate: Double suction pumps are capable of handling large volumes of fluid. The double - suction design allows for a greater flow area, enabling the pump to achieve higher flow rates compared to single - suction pumps of similar size. Good NPSH (Net Positive Suction Head) Characteristics: They generally have better NPSH requirements, which means they can operate effectively with a relatively low suction pressure. This makes them suitable for applications where the suction lift is limited or where the fluid source is at a lower level.
Application Fields
Industrial Applications: They are extensively used in industries such as power generation, steel, petrochemicals, and mining. In power plants, for example, double suction pumps are used for cooling water circulation, boiler feedwater, and other processes that require high - volume fluid transfer. Municipal Water Supply and Drainage: These pumps play a crucial role in municipal water treatment plants, water supply systems, and sewage treatment facilities. They are used to pump large amounts of water from sources such as rivers or reservoirs to treatment plants and then distribute the treated water to consumers. They are also used for stormwater drainage and sewage pumping.
