Description

Technical Field

[0001] The utility model relates to the technical field of double-suction pumps, in particular to a high-efficiency and energy-saving double-suction pump. Background Art

[0002] As an important form of centrifugal pump, the pump is widely used in engineering because of its high head and large flow rate. The impeller of this type of pump is actually composed of two back-to-back impellers. The water flowing out of the impellers flows into a volute.
