The SPD Series Multi-stage Centrifugal Pump is a horizontally configured, single-suction, and sectional-structured fluid transfer equipment, meticulously engineered with a focus on high-pressure stability and versatile compatibility. Its core design adheres to the principles of efficient fluid dynamics, ensuring smooth transfer of pure water and liquids with physical-chemical properties identical to pure water. The sectional construction allows for modular assembly, enabling easy adaptation to varying pressure and flow requirements.
This pump is a trusted choice for multiple high-demand scenarios, including industrial and agricultural water supply (e.g., factory production lines, farm irrigation systems), boiler feed systems (critical for power plants and manufacturing facilities), firefighting water circulation (supporting emergency response networks), municipal drainage (handling urban wastewater and rainwater), and high-rise building water supply (ensuring consistent water pressure across all floors). Compliant with the API 610 standard (latest revision), it meets global industrial quality benchmarks for reliability and safety.
Horizontal Single Suction Configuration: Guarantees uniform fluid intake, minimizing turbulence and enhancing operational stability compared to vertical pump designs.
Multistage Sectional Construction: Facilitates flexible adjustment of pressure levels, making it perfectly suited for high-head (up to 1050m) applications such as boiler feed and long-distance fluid transmission.
Centerline Support System: The pump casing adopts centerline support to withstand thermal expansion and heavy loads, maintaining structural integrity in harsh industrial environments.
Low Cavitation Risk: Advanced impeller design reduces vapor bubble formation, protecting internal components and sustaining high efficiency (even at fluctuating flow rates).
Dual-Suction First-Stage Impeller: A unique design exclusive to the SPD series, boosting flow capacity (up to 330 m³/h) and balancing axial thrust to extend the pump’s service life.
Precision-Machined Components: All critical parts undergo strict quality control, ensuring tight tolerances and consistent performance.
Interchangeable Parts: Standardized impellers, seals, and bearings enable quick replacements, reducing maintenance downtime and spare part costs.
Simplified Servicing: The horizontal layout allows easy access to internal components, eliminating the need for complex disassembly during routine checks.

The SPD Series features a robust mechanical seal (or optional packing seal) to prevent fluid leakage, while impellers are coated with wear-resistant materials to withstand long-term use. Bearings are selected for high-load capacity, ensuring smooth operation even under continuous working conditions.
Every unit undergoes hydrostatic pressure testing to validate casing integrity and leak resistance. Impellers are dynamically balanced to eliminate vibration, reducing wear on components and extending the pump’s operational lifespan. Additionally, the pump undergoes 24-hour continuous operation testing before delivery to ensure performance consistency.
The centerline support design maintains alignment stability at high temperatures, making the pump suitable for continuous operation in industrial settings such as refineries, chemical plants, and power stations. Its compliance with API 610 ensures compatibility with global industrial systems and simplifies integration into existing workflows.
The standard model is optimized for pure water and non-corrosive water-like liquids. For corrosive applications (e.g., chemical processing), we offer custom versions with 316 stainless steel casings and impellers—contact our engineering team for tailored specifications.
Routine maintenance includes checking the mechanical seal for leakage (monthly), inspecting bearing lubrication (quarterly), and cleaning the impeller (semi-annually for most industrial uses). The interchangeable components simplify repairs, minimizing downtime to within 2–4 hours for minor issues.
Absolutely—its high head (up to 1050m) and stable pressure output make it an ideal solution for high-rise buildings, ensuring consistent water supply to upper floors even during peak demand periods.
