Structural Features
- No shaft seal design
Adopting magnetic coupling drive or shielded motor technology, completely canceling the traditional mechanical seal or packing seal, realizing the complete static seal of power transmission process. This provides a reliable foundation for auxiliary control units such as the fuel pump control module, the control box for a well pump, and the fire pump controller, ensuring stable operation in hazardous or critical environments.
- Self-priming structure
Unique pump chamber and gas-liquid separation chamber design, together with high-efficiency reflux system, can quickly form a vacuum and complete the self-priming process during the initial startup or when there is gas in the inhalation pipeline.
Corrosion-resistant materials
The overflow parts (pump body, impeller, isolation sleeve, etc.) are made of high-quality stainless steel, fluoroplastic lining or special alloys, which are effective in resisting various types of chemical media erosion.
Product Advantages
Absolute anti-leakage
The non-moving seal structure fundamentally eliminates the risk of media leakage, protects the safety of operators and meets the most stringent environmental regulations, especially suitable for the transportation of highly toxic, high-risk, expensive or volatile media.
Convenient self-priming startup
No cumbersome pump filling and exhausting procedure before start-up, especially suitable for intermittent operation or working conditions where gas is easily stored on the suction side—a feature that simplifies demands on the control box for a well pump and ensures seamless integration with any fire pump controller.
Reliable operation and low maintenance cost
No fragile mechanical seals or packing devices, avoiding downtime for maintenance due to seal failure, significantly reducing the frequency of maintenance and replacement cost of spare parts.
Application Scenarios
Chemical Process
Circulation, transfer and charging of various acids, alkalis, salt solutions, organic solvents, intermediates and finished chemicals.
- Environmental protection water treatment
- Pharmaceuticals & Fine Chemicals
Transportation of APIs, intermediates, and solvents (e.g., ethanol, acetone) that require high purity and pollution prevention.
Service Assurance
- Accurate demand matching
Free on-site demand analysis, customized flow, pressure and piping configuration scheme;
