A single-stage double-suction pump is a special structural type of centrifugal pump. Its core feature is "single-stage impeller + double-sided water suction" — meaning the impeller has only one stage (distinguishing it from multi-stage pumps with multiple impeller sets), and liquid is sucked in simultaneously from the water inlets on both sides of the impeller. This structure endows it with the advantages of large flow rate, high efficiency, and stable operation, enabling it to adapt to the working condition requirements of "medium-low head and large flow rate". It is widely used in scenarios such as urban water supply, large-scale agricultural irrigation, industrial circulating water, and water conservancy projects, and is a core equipment for solving the problem of "insufficient flow rate of single-stage single-suction pumps".

Typical Application Scenarios

Urban Water Supply: Water treatment plants pump water from water sources (rivers, reservoirs) and deliver clean water to urban pipe networks; centralized water supply systems in residential areas or industrial parks to meet the water demand of large-scale users.

Agricultural Irrigation: Water delivery in the main canals of large-scale farmland irrigation areas (e.g., irrigation pumping stations for 10,000-mu fertile farmland), realizing rapid water replenishment through large flow rate.

Industrial Circulation: Delivery of circulating cooling water for power plant condensers, cooling circulating water for large reactors in chemical plants, and cooling water systems for steel rolling in iron and steel plants.

Water Conservancy & Emergency: Ecological water replenishment for rivers (pumping river water to replenish lakes and wetlands); urban flood drainage (pumping and draining water from large waterlogged areas during rainy seasons, such as stadiums and squares).
