Product Overview

The CQB-G High-Temperature Magnetic Drive Pump is a leak-free centrifugal pump specifically designed for the safe transfer of high-temperature and corrosive media. The pump components include a motor, magnetic coupling, water cooling system, and a corrosion-resistant centrifugal pump head. By replacing dynamic seals with a static sealing housing, the pumped media is completely isolated from the external environment, allowing the safe transfer of high-temperature, flammable, explosive, and hazardous liquids at temperatures up to 300°C.

Model Designation

CQB G High Temperature Magnetic Chemical Pump type 1 2

Key Features

  • Zero-Leakage Operation: The magnetic drive design ensures complete sealing and leak-free operation with no mechanical contact.

  • High-Temperature Resistance: The 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 coupling and motor, ensuring reliable operation under high-temperature conditions.

  • Low Vibration, Low Noise: The fixed coupling structure reduces vibration and operational noise.

  • Rear Pull Design: Optimizes axial length for improved heat dissipation and simplifies maintenance, reducing downtime.

Engineering Overview

The CQB-G pump uses non-contact magnetic coupling to transmit torque. When the motor drives the external magnetic rotor, the magnetic flux passes through the air gap and sealing housing to drive the internal magnetic rotor, causing the pump rotor to rotate synchronously with the motor without direct contact. The process liquid is completely enclosed within the fixed sealing housing, eliminating dynamic sealing points and fundamentally preventing leakage. Combined with high-temperature rare-earth permanent magnets and an independent water cooling system, the pump effectively isolates the motor’s thermal load, ensuring reliable and continuous operation under high-temperature conditions.

Typical Applications

The CQB-G pump is suitable for systems requiring:

  • Continuous or intermittent transfer of high-temperature fluids

  • Safe handling of flammable gases, explosive, sensitive, or toxic liquids

  • Leak-free operation in corrosive chemical processes

Typical industries include oil and petrochemical, chemical processing, pharmaceuticals, metallurgy, electroplating, environmental protection, food processing, film manufacturing, water treatment, and defense industries.

System Configuration

The CQB-G High-Temperature Magnetic Drive Pump system consists of the following main components:

  • Motor

  • Permanent Magnetic Coupling (Internal and External Rotors)

  • Fixed Sealing Housing

  • Water Cooling System

  • Corrosion-Resistant Centrifugal Pump Head

Wetted parts are made from corrosion-resistant materials such as 304, 304L, 316, 316L, UB6, CD4MCu, titanium alloys, and nickel-based alloys, selected according to the process media.

Components and Supply

  • Pump Body: Made from high-quality corrosion-resistant materials like stainless steel and duplex alloys.

  • Drive System: Permanent magnetic coupling ensures leak-free operation.

  • Electrical Control System: Includes intelligent controllers 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.

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

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

Operating Conditions

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

  • Maximum Working Pressure: ≤1.6 MPa

  • Maximum Medium Density: ≤1840 kg/m³

  • Kinematic Viscosity: ≤30 mm²/s

  • 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 pump must be flushed and drained immediately after shutdown.

Service Conditions

  • Regularly inspect sealing performance to ensure no leakage.

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

  • Avoid dry running to ensure proper lubrication and cooling.

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.
