Fluoroplastic Semi-submersible Pump

The FYH Series Semi Submersible Pump is commonly used in harsh industrial environments such as chemical processing, metallurgy, power generation, and acid washing. It effectively addresses the issues of severe corrosion and short seal life that plague traditional metal pumps when handling strong acids, strong alkalis, organic solvents, and strong oxidizing agents. Thanks to its vertical semi-submersible design, this pump can be installed deep within storage tanks and operates stably under complex temperature fluctuations ranging from -20°C to 90°C.

As a professional manufacturer of chemical pumps, Насос Чанъюй offers exceptional material customization capabilities for its FYH series pumps, with optional FEP or UHMWPE linings to ensure chemical stability. We can also customize production to meet your specific operational requirements.

Введение

Changyu Pump’s FYH series is a semi submersible pump that eliminates mechanical seals and is fully lined with fluoroplastic. It is a custom-engineered pump specifically designed for the “most challenging” tank lifting applications in industries such as chemicals, metallurgy, and pharmaceuticals.

Key issues this semi-submersible pump addresses:

  • Corrosion-resistant: Designed for highly acidic and alkaline environments, this corrosion-resistant pump features a full fluoroplastic (FEP/UHMWPE) lining, ensuring that even 98% concentrated sulfuric acid or fuming nitric acid cannot corrode the pump body.
  • Leak-proof: In designing this fluoroplastic pump, we eliminated mechanical seals from the physical structure, completely eradicating the common problem of vertical pumps leaking whenever seals are used.
  • Handles contaminated media: Even if the medium contains waste residue, particles, or fibers, this semi-submersible pump’s open impeller can handle it—swallowing and expelling it with ease.

This pump addresses two key concerns: first, avoiding frequent hoisting and maintenance; second, eliminating potential leakage risks. Through a minimalist design, Changyu Pump has minimized the number of wear parts, transforming what was once a cumbersome maintenance task into a simple process.

Вопросы и ответы

The biggest advantage of a sealess semi-submersible pump is the elimination of mechanical seals, which are the most common failure point in traditional vertical pumps. Without seals, the risk of leakage—especially when handling corrosive chemicals—is significantly reduced. This design improves operational safety, minimizes maintenance downtime, and lowers the total cost of ownership for chemical processing plants.

For highly corrosive media such as 98% concentrated sulfuric acid or fuming nitric acid, fluoroplastics like FEP or PFA are the best choices. These materials offer excellent chemical resistance and long-term durability, making them ideal for extreme pH environments and aggressive chemical transfer applications.

Yes, the FYH semi-submersible pump is manufactured under ISO 9001 quality management standards and complies with CE certification requirements. This ensures reliable performance, safety, and suitability for international industrial and chemical engineering projects.

Yes, the FYH series semi-submersible pump is designed to handle liquids with solid particles and short fibers. It uses an open double-balanced impeller, which allows solids to pass through without clogging. The balanced structure also reduces axial force, ensuring stable operation at speeds up to 2900 r/min, even in contaminated or “dirty” fluid applications.

The submerged depth should be determined based on the lowest liquid level in the tank to avoid dry running. The suction inlet must remain fully immersed during operation. FYH pumps support customized shaft lengths, ensuring proper installation while keeping the motor and bearings safely above the mounting plate.

Maintenance requirements are minimal due to the sealess design. Routine checks mainly include inspecting motor bearings and monitoring the wear condition of the fluoroplastic lining. This simple maintenance approach makes it a preferred solution for chemical transfer and wastewater treatment systems.
