FZB Series Fluoroplastic Self Priming Pump for Corrosive Chemical Transfer
The FZB series fluoroplastic self priming pumps are a new generation of corrosion-resistant self-priming centrifugal pumps developed by Changyu Pump. Based on the traditional ZX and ZW self-priming centrifugal pumps and utilising IHF’s fluoroplastic lining technology, these pumps retain the self-priming capabilities of the ZX and ZW models while significantly enhancing corrosion resistance through the fluoroplastic lining process.
The flange design complies with national standards, and the shaft seal employs an advanced external bellows mechanical seal. The self-priming head can reach up to 5 meters, and installing a check valve at the bottom can increase this by an additional 1–2 meters. This centrifugal pump only needs to be filled with liquid before its first use. When the liquid level is below 1.5 meters, it offers advantages over submersible pumps, including lower cost, easier maintenance, longer service life, and lower operating costs.

مقدمة
إن FZB Series fluoroplastic مضخة ذاتية التحضير من مضخة تشانغيو is a high-performance horizontal centrifugal pump specifically engineered for the transfer of highly corrosive chemicals. Unlike traditional pumps requiring manual priming, this series features an advanced self-priming chamber design, enabling an automatic suction lift of up to 5 meters after the initial liquid filling—a critical advantage for efficient and safe fluid handling from underground tanks or low-level sumps.
Built to withstand extreme chemical aggression, the FZB Series features wetted parts fully lined with premium fluoroplastics such as PTFE and FEP (F46). These materials offer exceptional corrosion resistance against any concentration of acids, alkalis, strong oxidizers, and organic solvents. The robust construction includes a cast steel outer casing and a silicon carbide mechanical seal that significantly reduces the risk of leakage and increases overall operational life. Whether applied in industrial sulfuric acid transfer, chemical wastewater treatment, or pharmaceutical processing, the FZB Series مضخة ذاتية التحضير delivers reliable, quiet, and low-maintenance performance in environments prone to severe corrosion.
Parts of Fluoroplastic Self Priming Pump
The FZB Series مضخة ذاتية التحضير features a robust horizontal structure with wetted parts fully lined in FEP(F46)/PTFE/PFA for extreme corrosion resistance. Key components include a cast steel casing, high-precision fluoroplastic impeller, and alumina ceramic shaft sleeve, all secured by an external bellows mechanical seal to ensure leak-free performance.

Working Principle of FZB Series Fluorine-lined Self-priming Pump
The FZB series utilizes an external-mix gas-liquid separation structure. Its core operation is defined by the process of “mixing, separation, and recirculation,” allowing the pump to evacuate air from the suction line without the need for a foot valve or manual priming after the initial setup.
1. The Priming Phase (Air Evacuation)
- Initial Charge: Before the first operation, the pump casing must be filled with liquid. This “priming liquid” is retained in the lower chamber for all future starts.
- Vacuum Creation: Upon startup, the high-speed rotation of the impeller flings the liquid toward the outer edge of the volute casing. This creates a low-pressure vacuum zone at the impeller eye (inlet).
- Gas-Liquid Mixing: Air from the suction pipe is drawn into the pump body due to the pressure differential. The impeller violently agitates the air and the priming liquid, creating a highly aerated gas-liquid mixture.
2. Gas-Liquid Separation
- The Separation Chamber: The mixture is forced into the oversized gas-liquid separation chamber at the top of the pump.
- Exhaust: Due to the sudden increase in flow area, the velocity drops significantly. The lighter air bubbles escape from the liquid and are discharged through the outlet pipe.
- Recirculation: The denser, degassed liquid sinks and returns to the impeller inlet via a dedicated recirculation port to pick up more air.
3. Normal Operation
- Continuous Cycle: This cycle repeats until all air is evacuated from the suction piping (reaching a self-priming height of up to 5 meters).
- Full Flow: Once the air is completely removed, the pump automatically transitions into a standard centrifugal operating mode, delivering a steady flow of corrosive media.
