CQ,CQB Stainless steel magnetic drive pump

Sealless magnetic-drive centrifugal pump engineered for corrosion-resistant, leak-free transfer of aggressive, toxic or volatile liquids. The magnetic coupling eliminates a dynamic shaft seal so the pump’s wetted components are fully contained — preventing shaft leakage, reducing maintenance and improving safety when handling acids, alkalis, solvents and other hazardous fluids.

Key features

• Sealless magnetic drive: driven by a permanent-magnet coupling to eliminate mechanical shaft seals and external leaks.
• Corrosion-resistant construction: available wetted materials include stainless steel, reinforced polypropylene and other engineering plastics, with ceramic and stainless steel internals where required.
• Compact, single-piece design: small footprint with low noise and reliable operation for continuous service.
• Low maintenance: simplified rotating assembly and no gland packing or stationary seals to replace.
• Safe handling of hazardous fluids: ideal for toxic, volatile, flammable or otherwise aggressive media where containment is critical.

Benefits for industrial users

• Improves plant safety and environmental compliance by preventing liquid emissions from seal failures.
• Extends service intervals and reduces spare-parts inventory compared with seal-equipped centrifugal pumps.
• Flexible material options let you match wetted parts to specific chemical compatibility and temperature requirements.
• Suitable for inline replacement or new installations in process, dosing and circulation systems.

Typical applications

• Chemical processing (acid/alkali circulation, solvent transfer)
• Pharmaceutical manufacturing
• Electroplating and surface treatment
• Petroleum and petrochemical handling (non-explosive zone installations)
• Food and beverage processes where corrosion resistance is required

Ordering notes

• Specify required wetted-material combination, temperature and pressure range, motor type and flange/connectivity when requesting a quotation.
• Example model from the series: 50CQ-25. Consult technical datasheets to confirm performance curves, allowable temperatures and compatibility with the intended fluid.
