Note: The performance data provided is based on clear water testing at 2900 r/min. Small to medium capacities utilize a 0.6 MPa all-plastic design. Large-capacity models (e.g., 80FSB-40, 80FSB-50, 100FSB-32) are structurally reinforced to withstand 1.6 MPa design pressures.
In chemical processing, wastewater treatment, and electronics manufacturing, engineers frequently require reliable fluid transfer solutions for highly corrosive media at low to moderate system pressures. While heavy-duty metal-lined pumps (such as the IHF series) are necessary for high-pressure pipeline networks, an all-plastic centrifugal pump offers a highly economical, efficient alternative for general chemical handling. The FSB series fluoroplastic centrifugal pump is engineered to meet this demand, utilizing advanced fluoropolymer molding techniques to provide exceptional chemical inertness within a compact footprint.
The primary defining characteristic of the FSB series is its structural material. Unlike lined pumps which rely on a cast-iron outer armor, the casing, impeller, and pump cover of the standard FSB pump are molded entirely from fluoroplastic alloy (predominantly F46 or Perfluoroethylene propylene). This homogeneous material structure eliminates the risk of lining separation or blistering under vacuum conditions.
F46 fluoroplastic provides extensive chemical resistance across a broad spectrum of industrial media. It safely handles continuous exposure to concentrated sulfuric acid, hydrochloric acid, nitric acid, strong alkalis, and reactive organic solvents. By eliminating metal from the wetted path, the FSB pump effectively prevents heavy-metal ion contamination of the process fluid, making it highly suitable for fine chemical synthesis, battery precursor manufacturing, and water treatment reagent dosing.
To prevent fugitive emissions and protect the environment, the FSB pump utilizes an advanced outboard bellows mechanical seal. In this configuration, the metallic components of the seal (such as the compression springs) are located outside the pump casing, completely isolated from the corrosive medium. The dynamic sealing interface typically pairs a 99.9% alumina ceramic or silicon carbide stationary ring against a PTFE-filled rotating ring. This material combination ensures low friction, high thermal conductivity, and highly reliable chemical compatibility.
Power transmission is achieved through a distinct structural design. The impeller and the mechanical seal shaft sleeve are integrated into a single unit. This integrated rotor connects to the pump shaft using a precise Morse taper fit, ensuring excellent concentricity and torque transmission while minimizing the number of internal sealing points. This design simplifies assembly and reduces the likelihood of shaft runout, which directly extends the operational life of the mechanical seal.
To accommodate different spatial constraints and operational preferences, the series is manufactured in two primary configurations:
