Model Designation

CQB-L Vertical Magnetic Pipeline Pump for Chemical Transfer

Applications

Typical Operating Scenarios

• Vertical pipeline transfer of corrosive liquids in chemical process lines
• Transfer of acid and alkali media in sealed industrial systems
• Hazardous fluid handling in petrochemical plants
• Electroplating and surface treatment fluid circulation
• Compact vertical pumping applications with limited footprint

Engineering Advantages

Structural Design Logic + Engineering Result

CQB-L pumps integrate a vertical pipeline magnetic drive with permanent magnet coupling and static isolation sleeve to transmit torque without dynamic seals, creating a completely enclosed flow path that eliminates the primary leakage risk of conventional mechanical seals. Corrosion-resistant wetted components (pump body, impeller, isolation sleeve) and wear-resistant shaft sleeves and bearings enhance service life and operational reliability. Vertical compact structure reduces footprint and simplifies installation.

✔ Magnetic drive and sealed isolation structure ensure leak-free operation, corrosion resistance and reliable vertical pipeline chemical transfer.
