S/SH Type Horizontal Double-suction Pump

The S-shaped horizontal double-suction pump is a single-stage centrifugal pump with a horizontally split pump casing and a double-suction impeller. The core design concept lies in balancing the axial force through the symmetrical double-suction impeller structure, and achieving unparalleled maintenance convenience by using the horizontally split pump casing. It has outstanding features such as smooth operation, high efficiency and energy saving, reliable performance, and convenient maintenance. It is the main equipment that undertakes the key water transportation tasks in urban water supply and drainage, large-scale water conservancy projects, industrial circulation systems, and regional water transfer projects.

Working conditions:
The medium's density should not exceed 1240 kg/m³;
The ambient temperature should be ≤ 50°C, and the medium temperature should be ≤ 80°C. Special requirements can reach up to 200°C;
The pH value of the medium: cast iron material is 6-9, stainless steel is 2-13;
The self-priming height should not exceed 4.5-5.5 meters, and the suction pipe length should be ≤ 10 meters;
The rotational speed is generally 1450 r/min to 3000 r/min.

* Electrically fully protected to prevent bumps during production transfer, protecting the stator coils
* Long-lasting durability. The bearings have a long service life, low noise, and energy savings
* High configuration without machine burn. Built-in overload protection, phase loss protection, no machine burn
* Good heat dissipation effect. The iron core and the casing are fully in contact, resulting in good heat dissipation and low operating temperature rise

The S-type horizontal double-suction pump is the standard configuration and reliable choice for large-scale water transportation applications. Its typical application scenarios include:
Municipal water supply and drainage: water intake and pumping stations of urban waterworks, intermediate pressure pumping stations in water distribution networks, inlet and outlet water lifting pumping stations for large sewage treatment plants, and rainwater discharge pumping stations.
Industrial circulation and energy: main pumps for cooling water in thermal power plants and nuclear power plants, cooling water and circulation water systems in industries such as steel, chemical, and paper manufacturing.
Large-scale water conservancy and water diversion projects: pressure pumping stations at all levels in cross-basin and long-distance water diversion projects, water intake and irrigation pumping stations for reservoirs and rivers.
Building and regional energy supply: central air conditioning cooling and hot water circulation systems in large commercial complexes, data centers, hospitals, and airports, as well as circulating water pumps in regional centralized heating networks.
Agricultural irrigation: main pumping stations for large and medium-sized irrigation districts to ensure agricultural water supply.
