Product Features
1. Superior non-clog performance: The unique single/double-blade impeller smoothly passes fibrous impurities up to 5 times the pump caliber and solid particles up to 50% of the pump caliber, effectively avoiding blockage failures.
2. Durable sealing system: Adopts hard corrosion-resistant tungsten carbide double-face mechanical seal. Operating stably in an oil chamber, it delivers outstanding wear and corrosion resistance and long continuous service life.
3. Safe and stable operation: The vertical submerged structure eliminates cavitation and air exhaust problems. The precisely machined pump shaft and reliable coupling ensure stable operation with a sufficient safety margin, supporting full-head overload-free operation.
4. Intelligent and convenient maintenance: The pump operates with low noise and high energy efficiency, and is easy to disassemble and maintain. The optional automatic liquid level control system realizes unattended automatic operation according to liquid level changes.
Main Application
Widely used in chemical, petrochemical, pharmaceutical, mining, papermaking, cement, steel, power and coal processing industries, as well as municipal sewage treatment plants, municipal engineering and construction sites. It is suitable for conveying solid and fiber-laden sewage, clean water and various corrosive media.
