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, Changyu Pump 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.

Introduction
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.
