Pumps | CQB-F Series
PTFE-Lined Magnetic Drive Pump

Product Overview
The CQB-F is a single-stage, single-suction chemical centrifugal magnetic drive pump built on modern magnetism principles, delivering non-contact indirect power transmission via permanent magnets for chemical process service.
Key Features
- Optimized construction refined from metallic magnetic pump designs with full fluoroplastic lining on all wetted components
- Exclusive compression sintering technology permanently bonds fluoroplastic liners to metal substrates to eliminate liner delamination
- Retains core leak-free advantage inherent to magnetic drive construction
- Overcomes poor corrosion resistance limitation of all-metal magnetic pumps when handling highly corrosive fluids
- Superior cost efficiency serving as optimal economical alternative to high-cost alloy-based magnetic pumps such as titanium and Hastelloy grades
- Non-contact indirect torque transmission via permanent magnets for zero leakage operation
- Dynamic shaft sealing fully replaced with static sealing to fully enclose all pump wetted components
- Simplified construction with low noise output and stable operation
- Environmentally safe zero-leakage pumping solution for widespread industrial applications
