The IHY Long-Axis Submersible Pump is a specialized, high-efficiency submersible pump designed for deep-well, industrial, and municipal applications, delivering reliable fluid transfer in demanding conditions. Featuring advanced long-axis design, robust materials, and precision-engineered hydraulics, the IHY pump is ideal for high-head, high-flow, and corrosive or abrasive fluid handling.
The long-axis design allows the pump to operate in deep water, large tanks, and industrial reservoirs, maintaining stable flow and reliable discharge pressure. It is widely used in municipal water supply, industrial water transfer, wastewater treatment, irrigation, flood control, and chemical industries.
The pump is constructed with high-grade stainless steel, alloy steel, or corrosion-resistant coatings to provide durability, chemical resistance, and wear resistance. Optional features include mechanical seals, thermal protection, variable frequency drive (VFD) compatibility, and PLC/SCADA integration, making it suitable for modern automated pumping systems.
The IHY pump series meets ISO, API, CE, and ISO 9001 standards, ensuring quality, safety, and long-term reliability for industrial and municipal operations.
