Self-Priming Chemical Pump – FZB Fluorine Lined Centrifugal Pump
The self-priming chemical pump developed by Bơm Changyu is designed for corrosive liquid transfer where suction conditions are difficult or the fluid level is below the pump inlet.
This FZB fluorine-lined centrifugal pump from Bơm Changyu is engineered for chemical industries requiring stable operation, corrosion resistance, and automatic self-priming capability without external priming systems.
Once initially filled, the pump can automatically evacuate air from the suction line and maintain continuous operation under demanding chemical conditions.
It is widely used in chemical processing systems where acids, alkalis, and solvents must be transferred safely and efficiently.

Why Choose a Self-Priming Chemical Pump
In chemical plants, pumping conditions are often complex:
- Liquid tanks are installed below ground level
- Fluids are highly corrosive or volatile
- Manual priming is unsafe or inconvenient
- Leakage risk must be minimized
A self-priming chemical pump eliminates the need for external priming systems and reduces operational risk.
Ưu điểm:
- Automatic self-priming after initial filling
- Safe handling of corrosive liquids
- Reduced operator intervention
- Stable suction performance under dry-start conditions
- Suitable for closed chemical transfer systems
Nguyên lý hoạt động
The pump operates based on a gas-liquid separation self-priming structure.
When the pump starts, the impeller creates a vacuum in the pump chamber. Air and liquid are mixed and circulated in the separation chamber. Air is discharged through the return path, while liquid is retained inside the casing until full priming is achieved.
Once primed, the self-priming chemical pump operates as a standard centrifugal pump, maintaining continuous flow without interruption.

Phụ tùng
The FZB-type fluoroplastic-lined self-priming chemical pump primarily consists of core components such as the fluoroplastic-lined pump body, impeller, self-priming device, shaft seal system, and drive unit. If you have specific operational conditions or selection requirements, we can provide further technical support and customized product services.
- Fluoroplastic-lined pump body: Constructed with a high-performance fluoroplastic lining, it offers excellent resistance to strong corrosive media and is suitable for various chemical liquids such as acids, alkalis, and solvents.
- Cánh quạt: Made of fluoroplastic or composite materials, it features superior corrosion resistance and hydraulic performance, enabling efficient medium transportation.
- Self-priming device: Integrated self-priming structure allows the pump to rapidly self-prime within the suction head range (e.g., 5 meters) without requiring priming liquid.
- Sealing system: Optional mechanical seals or leak-free magnetic drive systems are available to effectively prevent the leakage of hazardous media and enhance operational safety.
- Drive unit: Equipped with high-efficiency motors as standard, supporting various power ratings and explosion-proof grades to meet the needs of different industrial environments.
The wetted parts of the pump are lined with fluoroplastic materials, providing strong resistance to aggressive chemicals.
This structure allows the pump to handle:
- Strong acids (sulfuric, hydrochloric, nitric acid)
- Chất kiềm mạnh
- Dung môi hữu cơ
- Oxidizing chemical solutions
The fluorine lining isolates the metal body from direct contact with media, significantly extending service life in corrosive environments.
