Centrifugal Pump Double Suction
Large flow rate: It is equivalent to two single-suction impellers of the same diameter working at the same time. The flow rate can be doubled under the same impeller outer diameter, which can meet the transportation needs of large flow rates and is suitable for large industrial systems, urban water supply systems, etc.
High head: Double-suction pumps can produce higher head and can transport liquids to higher positions or longer distances to meet the height and pressure requirements in different engineering applications.
High efficiency: The unique structural design makes the flow of fluid in the pump smoother and reduces energy loss. Compared with traditional single-suction pumps, double-suction pumps can transport more fluids at the same power, thereby reducing energy consumption and improving pump efficiency.
Excellent water absorption performance: It has two suction ports, which can evenly inhale water flow and reduce axial force. Compared with single-suction pumps, its water absorption performance is better, which can effectively prevent the occurrence of cavitation and improve the operation stability and reliability of the pump.
It is an important type of centrifugal pump, with the characteristics of high head and large flow, and is widely used in various projects. Its impeller is composed of two back-to-back impellers. This design allows the double-suction pump to double the flow rate under the same impeller outer diameter.
Working principle
The double-suction pump works by driving the built-in rotating shaft and impeller through an electric motor. When the impeller rotates, due to the centrifugal force, the fluid is sent to the center of the impeller and flows to the outlet under the push of the blades. The double-suction pump adopts a symmetrical structure with impellers on both sides to reduce axial force and maintain the balance of the pump.
Double suction pumps are suitable for various occasions that require high flow and high head, such as urban water supply and drainage, agricultural irrigation and drainage, industrial applications, etc. It has a compact structure, stable operation, low noise, and is easy to install, use and maintain. Models and parameters Double suction pumps have a variety of models, including S-type single-stage double suction centrifugal pumps, DK-type multi-stage double suction centrifugal pumps, GS-type high-efficiency energy-saving double suction pumps, etc. DK-type multi-stage double suction split pumps are suitable for urban and industrial water supply and drainage, agricultural irrigation and drainage, etc. The conveying medium is clean water or similar liquids. The applicable temperature range is -20℃ to 80℃, the flow range is 18~1368m³/h, and the head can reach 100~360m
