CQG Stainless steel vertical pipeline magnetic pump

A vertical, in-line magnetic-drive centrifugal pump engineered for leak-free handling of hazardous and corrosive liquids. The pump uses a hermetic magnetic coupling to eliminate shaft seals and associated leakage risks, making it suitable for flammable, explosive, highly toxic and aggressive chemical fluids in process, chemical, petrochemical and pharmaceutical plants.

Key features

• Magnetic-drive (sealless) vertical in-line design for zero-leakage operation
• Flow components (pump casing, impeller, isolation sleeves) manufactured in stainless steel for corrosion resistance
• Shaft sleeves available in highly wear‑resistant silicon carbide and tungsten carbide for extended life in abrasive or erosive fluids
• Sliding bearings made from carbon graphite (M106K) with an integrated lubricating oil groove to improve bearing life and reliability
• Compact vertical installation: small footprint, low vibration, low noise and stable running
• Many parts interchangeable with CQB horizontal magnetic-drive series, enabling easier spare-part management and cross-replacement

Performance range (typical)

• Flow rate (Q): 3.2 – 100 m3/h
• Head (H): 20 – 80 m
• Motor power: 0.75 – 75 kW

Applications

• Transfer of flammable, toxic or corrosive process liquids where leakage is unacceptable
• Chemical dosing and circulation
• Corrosive solvent transfer in industrial processes
• Applications requiring compact vertical layout and reduced maintenance risk from seal failures

Ordering and selection notes

• Confirm fluid compatibility with stainless-steel wetted materials and available shaft sleeve options (silicon carbide, tungsten carbide)
• Verify required performance point (flow and head) to select the correct model and motor power
• For applications with specific metallurgy or certification needs (e.g., higher-alloy materials, ATEX, or sanitary finishes), request options and documentation from the supplier

Benefits for operations

• Eliminates dynamic shaft seals and associated routine maintenance and leak risks
• Robust bearing and sleeve materials reduce downtime from wear and corrosion
• Vertical in-line layout saves floor space and simplifies piping alignment
