Product Overview

The CQB-G High-Temperature Magnetic Drive Pump is a leak-free centrifugal pump designed specifically for the safe transfer of low-temperature and highly corrosive media. It uses a magnetic coupling system with a static sealing housing to transmit torque without mechanical contact, completely eliminating the leakage risks associated with traditional mechanical seals. The system integrates a drive motor, magnetic coupling, dedicated water cooling components, and corrosion-resistant pump heads, providing stable operation with a medium temperature up to 300°C, offering performance comparable to internationally leading products.

Model Designation

CQB-G High Temperature Magnetic Chemical Pump

Key Features

  • Zero-Leakage Operation: Magnetic drive system with no mechanical contact ensures a completely sealed and leak-free operation.

  • High-Temperature Resistance: High-temperature permanent magnets can handle media temperatures up to 300°C (typical continuous operation ≤280°C).

  • Multi-Loop Water Cooling System: Effectively controls the temperature of the magnetic components and the motor, ensuring stable operation in high-temperature conditions.

  • Low Vibration, Low Noise: Fixed coupling design reduces noise and vibration.

  • Rear Pull Structure: Optimized axial length for simplified maintenance and reduced downtime.

Engineering Overview

The CQB-G pump utilizes magnetic drive technology, with torque transmitted through both external and internal magnetic coupling, allowing the pump rotor to rotate synchronously with the motor without direct contact. The process liquid is completely enclosed within a fixed sealing housing, eliminating all dynamic sealing interfaces and preventing leakage. The high-temperature rare earth permanent magnets combined with an independent water-cooling system effectively isolate the motor’s thermal load, ensuring reliable, continuous operation at high temperatures.

Typical Applications

CQB-G pumps are widely used in:

  • High-Temperature, Flammable, and Explosive Liquids

  • Toxic, Corrosive, and Sensitive Media

  • Rare and High-Value Chemical Fluids

These pumps are especially suitable for industries including oil and petrochemical, chemical processing, pharmaceutical manufacturing, metallurgy, electroplating, environmental protection, food processing, film manufacturing, water treatment, and defense industries. They are ideal for applications where leak prevention, flammability, or explosion risks must meet high safety standards.

System Configuration

The CQB-G high-temperature magnetic drive pump system consists of the following main components:

  • Drive Motor

  • Magnetic Coupling Components (Internal and External Magnets)

  • Static Housing

  • Water Cooling System

  • Corrosion-Resistant Centrifugal Pump Head

All wetted parts are made from corrosion-resistant materials such as stainless steel, duplex alloys, titanium alloys, and nickel-based alloys, to suit various process media and ensure durability and corrosion resistance.

Components and Supply

  • Pump Body: Made from reinforced polypropylene (PP) or stainless steel for excellent corrosion resistance.

  • Drive System: Features a high-efficiency magnetic coupling design for leak-free operation.

  • Electrical Control System: Equipped with an intelligent controller for comprehensive system protection.

  • Bearing System: Self-lubricating bearings rely on the conveyed medium for cooling and lubrication.

Technical Service

  • 24/7 customer service and technical support available.

  • Regular maintenance and fault diagnostics to ensure long-term, stable operation of the pump system.

  • Custom solutions based on customer needs, providing tailored pump system configurations and solutions.

Operating Conditions

  • Maximum Medium Temperature: Up to 300°C (typical continuous operation ≤280°C)

  • Maximum System Pressure: ≤1.6 MPa

  • Medium Density: ≤1840 kg/m³

  • Kinematic Viscosity: ≤30 cSt

  • Medium Requirement: Free of hard particles and fibers

Bearings are cooled and lubricated by the pumped medium; dry running is prohibited. For media prone to crystallization or precipitation, the system must be flushed and drained immediately after shutdown.

Service Conditions

  • Regularly inspect sealing performance to ensure no leakage.

  • Check all fasteners to ensure the installation is secure, preventing vibration and loosening.

  • Avoid dry running to ensure proper lubrication and cooling functions.

Protection Features

  • Overload Protection: Prevents pump damage during overload operation.

  • Overheating Protection: Automatically stops the motor if the temperature exceeds preset limits.

  • Low Liquid Level Protection: Automatically detects liquid levels to avoid dry running.

Selection Criteria

When selecting the CQB-G high-temperature magnetic drive pump, consider the following criteria:

  • Medium Type: Choose a pump suitable for the characteristics of the medium being conveyed.

  • Installation Environment: Select a pump system suitable for high-temperature environments and special requirements.

  • Flow and Head Requirements: Choose the appropriate flow and head based on system needs.
