Product Introduction: The Series represents the ultimate solution for safely transferring highly aggressive, corrosive, and high-purity chemicals. This pump combines the mechanical strength of a robust cast iron casing with the near-universal chemical inertness of a thick, seamless fluoropolymer (PTFE or PFA) lining. It is engineered to handle the most demanding applications where exotic metal alloys are either prohibitively expensive or chemically unsuitable. The Series provides an unmatched level of performance, reliability, and safety for industries that cannot compromise on chemical compatibility.
Operating Principle & Design: While operating on the standard centrifugal principle, the design philosophy of the pump is centered on chemical isolation.
- Lining Technology: The core of the pump is its molded lining. A thick layer (typically 3-5mm) of virgin PFA (Perfluoroalkoxy) or PTFE (Polytetrafluoroethylene) is locked into the interior of a ductile iron or cast steel casing. This process creates a seamless, non-porous barrier that completely isolates the metal armor from the corrosive fluid. This unique construction provides the strength to handle high pressures and pipe loads while offering the chemical resistance of a non-metallic pump.
- Lined Impeller: The impeller, the main rotating component, consists of a metal core completely encapsulated in a thick molding of PFA/PTFE, ensuring that no metallic parts are exposed to the process fluid.
- Advanced Sealing System: The pump is fitted with externally mounted, specialized mechanical seals designed for corrosive duties. These seals utilize chemically inert materials such as Silicon Carbide, Carbon, and PTFE to prevent any leakage of hazardous fluids, ensuring environmental and operator safety.
Key Features & Benefits:
- Exceptional Chemical Resistance: The fluoropolymer lining is inert to nearly all industrial chemicals, including concentrated acids, alkalis, solvents, and halogens, across a broad temperature range.
- Cost-Effective Performance: Delivers the performance and chemical compatibility of expensive exotic alloys (like Hastelloy, Titanium) at a fraction of the cost, providing a superior return on investment.
- High-Purity Applications: The inert, non-leaching PFA/PTFE surfaces make the pump ideal for applications where fluid purity is critical, such as in the pharmaceutical and electronics industries.
- Mechanical Strength & Durability: The rigid metal casing protects the pump from mechanical shock and piping strain, providing a much more robust solution than solid plastic pumps.
- Abrasion Resistant: The inherent non-stick properties of PTFE and the resilience of PFA provide good resistance to slurries with moderate abrasive content.
Common Applications:
The Series is the pump of choice for the most severe chemical handling tasks:
- Bulk Chemical Production: Transfer of highly concentrated sulfuric, nitric, hydrochloric, and hydrofluoric acids.
- Chlor-Alkali Industry: Safely handling wet chlorine gas, sodium hypochlorite, and caustic soda.
- Steel Manufacturing: Used in acid pickling lines and acid regeneration plants.
- Pharmaceutical & Semiconductor: Transferring ultra-pure chemicals, solvents, and deionized water where contamination is not an option.
- Agrochemicals: Pumping raw ingredients and finished products for pesticides and fertilizers.
- Wastewater Treatment: Handling aggressive chemical cocktails and pH control chemicals.
