Close-Coupled PFA Lined Chemical Pump

Product Introduction: The Series is a compact, high-performance chemical pump featuring a robust ductile iron casing lined with pure, seamless PFA (Perfluoroalkoxy). Engineered in a close-coupled (monoblock) design, this pump offers an exceptionally space-saving and installation-friendly solution for handling the most corrosive, toxic, and high-purity fluids. It combines the near-universal chemical inertness of PFA with a design that eliminates alignment issues, making it the top choice for OEM skid systems, chemical dosing packages, and plant retrofits where space and reliability are critical.

Design Philosophy & Construction: The Series is engineered for maximum performance in a minimal footprint.

  • PFA Lining Technology: The pump’s wetted parts are protected by a thick, uniform layer of PFA, applied using a high-pressure transfer molding process. This creates an extremely smooth, non-porous surface that is free of seams or welds. PFA offers exceptional high-temperature performance and the highest purity levels, making it superior for sensitive applications.
  • Close-Coupled (Monoblock) Design: The pump casing is mounted directly to a specially designed motor flange, and the impeller is mounted on an extended, heavy-duty motor shaft. This single-unit construction eliminates the need for a separate baseplate, coupling, and the time-consuming process of shaft alignment, resulting in a perfectly aligned, vibration-free unit from the factory.
  • Durable Metal Armor: The external casing is made from high-strength ductile iron, which provides full mechanical protection for the PFA lining and ensures high pressure-handling capabilities and resistance to external pipe loads.
  • Advanced External Seal: To ensure maximum safety, the pump is fitted with an externally mounted mechanical seal. This keeps the seal’s metal components isolated from the corrosive fluid, extending its life and guaranteeing leak-free operation.

Key Features & Benefits:

  • Ultimate Chemical Resistance: The pure PFA lining is chemically inert to nearly all acids, solvents, alkalis, and other aggressive chemicals, even at elevated temperatures.
  • Compact, Space-Saving Footprint: The monoblock design is significantly smaller than traditional long-coupled pumps, making it ideal for installation in tight spaces.
  • Simplified Installation & Maintenance: With no on-site alignment required and fewer components, the pump is faster to install and easier to service.
  • Guaranteed Perfect Alignment: The fixed alignment between the motor and pump eliminates a primary cause of premature bearing and seal failure, greatly enhancing reliability.
  • High-Purity Service: The ultra-smooth, non-leaching PFA surface prevents fluid contamination, making it perfect for semiconductor, pharmaceutical, and reagent-grade chemical applications.

Common Applications:

The compact and reliable design of the Series makes it ideal for:

  • OEM and Skid-Mounted Systems: Chemical dosing, filtration, and purification packages.
  • Semiconductor & Electronics: Transfer of ultra-pure acids, etchants, and solvents in cleanroom environments.
  • Pharmaceutical & Biotech: Handling aggressive reagents, purified water, and sterile process fluids.
  • Laboratories and Pilot Plants: Safe and reliable transfer of high-value or hazardous chemicals.
  • Chemical Unloading and Transfer: Pumping concentrated chemicals from totes, drums, and day tanks.
  • Pollution Control: Dosing of harsh chemicals in water and air treatment systems.
