S/SH Series Double-Suction Split-Case Centrifugal Pumps
The S/SH Series double-suction split-case centrifugal pump, a critical variant of centrifugal pumps, excels in high-head, high-flow applications. Its unique dual-impeller design combines two back-to-back impellers discharging into a shared volute, enabling doubled flow capacity compared to single-suction pumps of equivalent diameter. Engineered for reliability and ease of maintenance, this horizontal split-case pump is ideal for demanding industrial, municipal, and agricultural applications.
Key Features
Dual-Impeller Design
Symmetrical double-suction impeller eliminates axial thrust, ensuring smooth operation and extended bearing life.
Horizontally split casing allows rapid inspection and maintenance without disassembling pipelines or motors.
Robust Construction
Materials: Shafts made of high-quality carbon steel; pump body, cover, and impeller cast from durable iron.
Sealing: Options include BURGMANN mechanical seals or soft packing seals with water-cooled lantern rings for leak-free operation (up to 8,000 hours).
Bearings: SKF/NSK precision bearings ensure low-noise, vibration-free performance with grease lubrication.
Versatile Installation
Inlet/outlet ports aligned perpendicular to the shaft for flexible pipeline integration.
Supports vertical or horizontal installation to suit site conditions.
High Efficiency & Anti-Cavitation
Hydrodynamically optimized impeller with precision-cast surfaces minimizes turbulence and cavitation.
Smooth internal flow paths reduce hydraulic losses, achieving peak efficiency.
Applications
Fluids: Clean water or liquids with similar physical/chemical properties (max. temperature: 80°C).
Industries:
◦ Municipal water supply, drainage, and irrigation systems.
◦ Power plants, mining operations, and large-scale hydraulic engineering.
◦ Agricultural flood control and irrigation networks.
Available Models:
6Sh-6, 6Sh-6A, 6Sh-9, 6Sh-9A, 8Sh-6, 8Sh-9, 8Sh-9A, 8Sh-13, 8Sh-13A, 10Sh-9, 10Sh-9A, 10Sh-13, 10Sh-13A, 10Sh-19, 10Sh-19A, 12Sh-6, 12Sh-6A, 12Sh-68, 12Sh-9, 12Sh-9A, 12Sh-98, 12Sh-13, 12Sh-13A, 12Sh-19, 12Sh-19A, 14Sh-6, 14Sh-6A, 14Sh-68, 14Sh-9, 14Sh-9A, 14Sh-98, 14Sh-13, 14Sh-13A.
Efficiency Optimization & Solutions
Common Causes of Efficiency Loss:
Surface Roughness: Erosion increases flow resistance, reducing hydraulic efficiency.
Scaling/Corrosion: Deposits shrink flow paths and raise head losses.
Casting Defects/Cavitation: Pitting or cracks induce vortex energy losses.
Mechanical Wear: Seal and bearing degradation lowers volumetric/mechanical efficiency.
Performance Enhancement Strategies:
Polymer Composite Coating
Applies a hydraulically smooth surface (20x smoother than polished stainless steel) to impellers and internal surfaces.
Reduces friction, turbulence, and corrosion while improving hydraulic/volumetric efficiency.
Shields against electrochemical corrosion and extends component lifespan.
Advanced Sealing & Lubrication
Blu-Goo Super Lubricant: Minimizes friction in bearings, seals, and threaded joints, withstanding extreme pressure (1,407 kg/cm²) and temperatures up to 316°C.
Reduces mechanical losses, noise, and energy consumption while preventing leaks.
Technical Specifications
Pressure Limits:
Max suction pressure: 1.0 MPa.
System pressure: ≤1.6 MPa (customizable for higher pressures with cast steel components).
Ambient Conditions:
Temperature: <40°C; Humidity: <95%.
Fluid Requirements:
