The HYF Fluoroplastic Submersible Pump is a specialized submersible pump engineered for handling highly corrosive, chemical, and industrial fluids. Constructed with advanced fluoroplastic (PTFE, PVDF, or FEP) materials combined with high-grade stainless steel components, this pump offers exceptional chemical resistance, long-term durability, and reliable performance in aggressive environments.
Designed for fully submerged operation, the HYF pump eliminates the need for priming and ensures quiet, energy-efficient, and leak-free fluid transfer. Its hydraulically optimized impeller and casing design provide stable flow, reduced vibration, and high efficiency, making it ideal for chemical processing plants, industrial wastewater management, and corrosive fluid transport.
The pump is widely applied in acid, alkali, and other chemical solution transfer, fluorochemical production, electroplating processes, and hazardous liquid handling. Optional features include mechanical seals, dual motor protection, variable frequency drive (VFD) compatibility, and PLC/SCADA integration, enabling full automation and remote monitoring.
The HYF fluoroplastic submersible pump complies with ISO 2858, API 610, CE, and ISO 9001 standards, ensuring reliable operation, safety, and quality across global markets.
