GSMNf horizontal split-casing centrifugal fire pump

OVERVIEW

The horizontal split-case centrifugal fire pump is a robust and reliable fire protection solution, designed to deliver high flow rates with efficient operation. It is commonly used in various fire suppression systems where consistent water pressure and flow are crucial.

Key Features

• Split-Case Design: The pump casing is horizontally split, which allows for easy access to the internal components (such as the impeller and shaft) for maintenance and inspection without disturbing the piping or alignment.
• High Efficiency: The design facilitates smooth water flow through the pump, reducing turbulence and energy loss, which leads to higher efficiency.
• Durability: Built with durable materials such as cast iron or stainless steel, the pump is designed to withstand harsh conditions and prolonged use in demanding environments.
• Stable Operation: The horizontal configuration provides stability and minimizes vibration, which enhances the overall performance and longevity of the pump.
• Dual Suction Impeller: The pump often features a dual suction impeller, which helps to balance the hydraulic forces within the pump, resulting in reduced axial thrust and longer bearing life.
• Versatility: Suitable for both fresh water and seawater applications, it can handle a wide range of pressures and flows.

Applications

• Large Industrial Facilities: Often used in large manufacturing plants, refineries, and chemical processing plants where high-capacity fire protection is essential.
• Power Plants: Employed in power generation facilities to protect critical infrastructure.
• Municipal Water Systems: Used in municipal water supply systems to ensure adequate pressure for fire hydrants and firefighting systems.
• Commercial Buildings: Ideal for high-rise buildings, shopping centers, and other commercial properties requiring reliable fire protection.
• Hospitals and Educational Institutions: Provides fire safety in environments where protection of life and property is paramount.
• Public Infrastructure: Deployed in airports, railway stations, and other public facilities where large-scale fire suppression systems are necessary.

Advantages

• Attractive Design: The pump body features a streamlined design with reinforcement ribs, giving it an aesthetically pleasing appearance.
• Advanced Hydraulic Model: Optimized using CFD hydraulic modeling, which enhances pump efficiency and expands the operating range. Castings are made using resin sand molds, and flow components are precision-shaped using CNC molds, ensuring dimensional accuracy and surface smoothness.
• Superior Structural Design: Key structural components are optimized using FEM to ensure the rationality and load-bearing capacity of the design.
• High-Efficiency Motor: Equipped with a high-efficiency three-phase asynchronous motor, meeting the energy efficiency standards of GB-18613, with an insulation class of F.
• Stable Operation: The horizontal structure provides greater stability, especially in high-power applications, compared to vertical designs.
• Low Noise and Long Lifespan: The pump operates smoothly with low noise and minimal vibration, ensuring high concentricity of components and extended service life.
• Reliable Sealing, No Leakage: The shaft seal is made of durable materials like hard alloy and silicon carbide, providing reliable, leak-proof performance.
