centrifugal pump

The types of centrifugal pumps mainly include single-stage single suction, multi-stage single suction, single-stage double suction and other design structures, including pipeline, submersible, self-priming, submersible and other forms. The main components of a centrifugal pump include the impeller, pump casing, and shaft seal device. The function of the impeller is to directly transfer the mechanical energy of the prime mover to the liquid, in order to increase the static pressure energy and kinetic energy of the liquid (mainly increasing static pressure energy). The impeller generally has 6-12 rear curved blades, including open, semi closed, and closed types. Open impellers have no cover plates on both sides of the blades, making them easy to manufacture and clean. They are suitable for conveying materials containing a large amount of suspended solids, with low efficiency and low liquid pressure; The semi closed impeller has no cover plate on one side of the suction port and a cover plate on the other side, which is suitable for conveying materials that are prone to sedimentation or contain particles, and has lower efficiency; The closed impeller has front and rear cover plates on both sides of the blade, which has high efficiency. Shanghai Meiyanyi Pump Valve is one of the major centrifugal pump manufacturers in China, mainly producing centrifugal pump products suitable for conveying clean liquids without impurities. We provide you with various specifications and types of centrifugal pump product pictures and drawings, and welcome new and old customers to choose.
