OVERVIEW

The Long Shaft Vertical Turbine Fire Pump is a high-efficiency, heavy-duty vertical turbine pump specifically engineered for fire protection systems. It is designed to draw large volumes of water from deep wells, reservoirs, or other open water sources to meet demanding firefighting requirements. Featuring an extended shaft-driven configuration, the pump operates with the motor or diesel engine mounted above ground, transmitting power through a long vertical shaft to a multi-stage turbine impeller assembly submerged below water level. This ensures reliable water supply even in low-level or deep-water conditions.

APPLICATIONS

• Industrial & commercial fire protection systems

• Municipal water supply & firefighting networks

• High-risk facilities (petrochemical plants, power stations)

• Agricultural irrigation & emergency dewatering

FEATURES

1. High-Performance Design – Multi-stage turbine impellers deliver high-pressure, high-flow output compliant with NFPA, UL, FM, and other international fire safety standards.

2. Deep-Water/Low-Level Capability – Customizable shaft length allows installation in deep or variable water sources.

3. Robust Construction – Corrosion-resistant materials (cast iron, stainless steel, or bronze) ensure durability in clean or mildly contaminated water.

4. Flexible Drive Options – Electric motor or diesel-engine driven, with automatic control panels for seamless operation, monitoring, and fail-safe protection.

5. Low-Maintenance Design – Modular construction simplifies servicing, while long-life bearings and seals minimize downtime.

ADVANTAGES

• Advanced Hydraulics Model: Utilizes CFD hydraulic modeling for optimized design, improving pump efficiency and expanding its operational range. Castings use resin sand molding, and the flow components’ molds are CNC-machined, ensuring precise dimensions and smooth surfaces.
• Optimized Pump Design: Employs FEM (Finite Element Method) for structural optimization, validating the design’s rationality and load-bearing capacity.
• Energy-Efficient Motor: Features a high-efficiency three-phase asynchronous motor, meeting national standards GB-18613 for energy efficiency with an insulation grade of F.
• Stable Operation: Horizontal structure provides enhanced stability during high-power operations compared to vertical designs.
• Low Noise: The pump operates smoothly with minimal noise, and high concentricity of components ensures quiet performance.
• Reliable Sealing and Leak-Free Operation: Mechanical seals made from hard materials such as tungsten carbide and silicon carbide ensure durability and prevent leakage.
