CQB-G high temperature magnetic drive centrifugal chemical transfer pump

Magnetic-drive centrifugal pump designed for leak-free transfer of high‑temperature, volatile and corrosive liquids. The unit uses a hermetically sealed fluid chamber and a permanent‑magnet coupling to transmit torque without mechanical shaft seals, eliminating dynamic seal leakage risks.

Key features

• Magnetic coupling with high‑temperature rare‑earth permanent magnets capable of transmitting strong torque at liquid temperatures up to 280 °C.
• Hermetic isolation sleeve: pumped liquid remains enclosed, so there is no dynamic shaft seal or associated leakage.
• Water‑cooling jacket located between the motor and magnetic coupling to prevent heat transfer to the motor and ensure reliable operation at elevated process temperatures.
• Corrosion‑resistant centrifugal pump wet end suitable for aggressive fluids (specific metallurgy not provided — confirm alloy for your process).
• Compact assembly: motor, magnetic coupling, water cooling device and centrifugal pump integrated for industrial installations.

Typical performance limits (as provided)

• Maximum liquid temperature: ≤ 280 °C
• Maximum working pressure: < 1.6 MPa
• Maximum liquid density: ≤ 1,840 kg/m3
• Maximum kinematic viscosity: ≤ 30 cm2/s (cSt)
• Fluid cleanliness: liquids should be free of hard particles and fibrous impurities

Benefits for B2B users

• Eliminates seal-related leaks and fugitive emissions — improves safety when handling flammable, toxic or volatile fluids.
• Suited for high‑temperature service where conventional seal systems would fail.
• Reduces maintenance downtime by removing mechanical seal components and associated replacement tasks.
• Applicable across multiple industries: chemical processing, petrochemical, pharmaceuticals, electroplating, smelting, environmental treatment, printing/coating, food processing (verify compatibility), and national defense applications.

Typical applications

• Transfer of high‑temperature corrosive liquids
• Handling of toxic, volatile or flammable process media where leak prevention is critical
• Duty services in chemical plants, refineries, plating lines, and high‑temperature process circuits

Ordering / selection notes

• Confirm wetted materials and motor specifications for your chemical compatibility and temperature requirements.
• Verify required flange sizes, flow/pressure duty point, and cooling water supply for the water‑cooling jacket.
• Suitable only for liquids without abrasive solids or long fibers; for slurry or particulate service select an alternative design.
