Product description
Double suction centrifugal water pump
The working principle of a double suction pump is based on the basic principle of a centrifugal pump
Impeller design: The impeller of a double suction pump consists of two back-to-back impellers, which allows liquid to enter from both ends of the impeller simultaneously, thereby increasing the flow rate.
The operation of a double suction pump
The role of centrifugal force: When the impeller rotates at high speed, the liquid is thrown out of the impeller under the action of centrifugal force, forming a high-pressure area.
Formation of Low Pressure Zone: A low-pressure zone is formed at the center of the impeller, where atmospheric pressure continuously draws liquid into the center of the impeller.
Circulation process: After the liquid is thrown out, it flows into the pressurized water pipeline through the volute, forming a continuous suction and discharge process.
Difference from single suction pump
Water inlet method: Double suction pumps inlet water from both ends of the impeller, while single suction pumps inlet water from one end of the impeller.
Flow rate: Due to the design of the double suction pump impeller, its flow rate can be doubled under the same impeller outer diameter.
Price: Double suction pumps are usually priced higher than single suction pumps due to their complex structural design.
Double suction pumps have been widely used in engineering due to their high flow rate and head characteristics. For example, in transportation systems that require a large amount of fluid, double suction pumps can effectively meet the demand, and their horizontally split pump casing design is also easy to inspect and maintain. In addition, the design of the inlet and outlet of the double suction pump in the same direction and perpendicular to the pump shaft is beneficial for the layout and installation of the pump and inlet and outlet pipes.
