CQW stainless steel magnetic vortex pump

Sealless, magnetic-drive vortex centrifugal pump engineered for leak-free handling of corrosive, volatile or toxic liquids. The magnetic coupling eliminates a conventional shaft seal so the fluid is contained within the pump housing, delivering safe, reliable transfer of acids, alkalis, oils, rare or volatile liquids, and other hazardous media.

Key features

• Magnetic-drive (sealless) construction for zero-leak operation when handling hazardous or flammable fluids
• Stainless-steel wetted components for corrosion resistance and chemical compatibility
• Compact, lightweight design with a simple, service-friendly layout
• Designed for relatively high head and low flow applications; typical specific speed < 40
• Self-lubricating bearing circuit to extend sliding bearing life
• Optional cooling loop to remove eddy-current heat from the magnetic assembly
• Cantilever impeller design reduces radial loading on the shaft and bearings
• Performance sensitive to fluid viscosity — efficiency decreases as viscosity increases; best suited to low-viscosity liquids

Typical applications

• Chemical processing and electroplating lines
• Pharmaceutical and laboratory transfer duties
• Petroleum and petrochemical auxiliary services
• Food processing and photographic chemical systems
• Circulation and filtration systems where leak containment is critical
• Any application requiring safe transfer of flammable, toxic, or hard-to-seal fluids

Supply and specification notes

• Suitable for applications requiring a compact, low-maintenance sealless pump with good chemical resistance
• Confirm compatibility (temperature, pressure, specific chemical) and viscosity limits with supplier before specifying
• Model example: CQW series (e.g., CQW20-20); MPN CQW
