Product Description
Model Code Explanation
Product Introduction
CQB-G high-temperature magnetic pump (hereinafter referred to as high-temperature magnetic pump) is generally composed of four main parts: motor, magnetic coupling, water-cooling device and corrosion-resistant centrifugal pump head. Its key feature is the use of a magnetic coupling to transmit power.
When the motor drives the outer magnetic rotor of the coupling to rotate, magnetic field lines pass through the gap and isolation sleeve and act on the inner magnetic rotor, causing the chemical pump rotor to rotate synchronously with the motor and transmitting torque without mechanical contact.
At the power input end of the heat-preservation magnetic pump, the liquid is confined inside a stationary isolation sleeve. Since there is no dynamic seal, the pump is completely leak-free.
The magnetic materials of the magnetic coupling are made from high-temperature-resistant rare-earth permanent magnet materials, which can withstand high-temperature media up to 300°C while maintaining strong magnetic torque. A water-cooling device is installed between the motor and magnetic coupling to prevent the heat of the pumped high-temperature medium from being conducted to the motor, thus ensuring normal motor operation and achieving leak-free transfer of high-temperature media.
CQB-G high-temperature magnetic pump is a newly developed, fully leak-free corrosion-resistant pump from a national joint design program. Its technical and economic indicators are close to those of similar foreign products, and its configuration, basic parameters and technical performance comply with relevant standards.
The wetted parts of the pump can be manufactured from corrosion-resistant materials such as 304, 304L, 302, 321, 316, 316L, UB6, CD4Mcu, titanium alloys and nickel-based alloys depending on the medium.
Product Features
CQB-G high-temperature magnetic pump adopts a multi-loop circulation cooling structure, ensuring the reliability and stability of the prime mover and magnetic drive. At the same time, it uses a pin-type coupling to reduce pump noise and vibration. The combination of a quick-disassembly structure with the pin-type coupling increases the overall pump length, which is more conducive to heat dissipation.
This design also makes user maintenance or part replacement very convenient. In addition, cooling fan blades are designed on the outer rotor assembly to ensure the stability of the magnetic steel.
CQB-G high-temperature magnetic pump is suitable for conveying high-temperature media with temperatures ≤ 300°C.
Operating Conditions
CQB-G high-temperature magnetic pump is suitable for use in industries such as petroleum, chemical, pharmaceutical, smelting, electroplating, environmental protection, food, film processing and photographic developing, water treatment and national defense. It is an ideal unit for transferring high-temperature flammable, explosive, volatile, toxic, rare and precious liquids and various corrosive liquids.
It is suitable for conveying liquids in systems with a working pressure ≤ 1.6 MPa, temperature not exceeding 300°C, density less than 1840 kg/m³, and kinematic viscosity not greater than 30 cm²/s, and which do not contain hard particles or fibers.

Preparation Work
Installation and Operating Instructions
(1) CQB-G high-temperature magnetic pump should be installed horizontally. Before startup, check the lubricant level in the cooling chamber. If the oil level is too low, replenish it in time. Before starting the pump, the cooling water circuit should be opened first. The opening degree of the inlet valve should be adjusted according to the temperature of the cooling water outlet after the pump is in normal operation.
(2) When the liquid level on the suction side is above the pump shaft centerline, simply open the suction pipeline valve before starting. If the liquid level is below the pump shaft centerline, a foot valve must be installed on the suction pipeline.
(3) Before operation, inspect the pump: the motor fan should rotate flexibly, without sticking or abnormal noise, and all fasteners should be tightened.
(4) Check whether the motor rotation direction is consistent with the rotation arrow on the magnetic pump.
(5) After the motor is started, slowly open the discharge valve. When the pump enters normal operating condition, adjust the discharge valve to the required opening. Before stopping the pump, close the discharge valve first, then cut off the power supply, and finally close the cooling water valve.
Notes
(1) The cooling and lubrication of the CQB-G high-temperature magnetic pump bearings rely on the pumped medium, so dry running is strictly prohibited. Also avoid restarting the pump after a power failure during operation if this would cause dry running.
(2) If the pumped medium contains solid particles, a strainer must be installed at the pump inlet. If it contains ferromagnetic particles, a magnetic filter must be installed.
(3) The pumped medium and its temperature must be within the allowable range of the pump materials. The operating temperature of the pump is < 280°C, working pressure 1.6 MPa, density not greater than 1840 kg/m³, and kinematic viscosity not greater than 30 cm²/s, without hard particles or fibers. Special operating conditions must strictly follow the contractual agreement.
(4) For media that are prone to precipitation or crystallization, the pump should be flushed and drained in time after use to remove any residual liquid inside the pump.
(5) After every 1000 hours of normal operation, the bearings and end-face moving ring should be disassembled and inspected for wear, and any worn parts that are no longer suitable for use must be replaced.
(6) The inner and outer magnetic couplings of this pump series use high-performance permanent magnet materials, which may pose a potential hazard to the following items. Please keep these items at a safe distance from the pump: pacemakers, credit cards and other magnetic cards, calculators, computer disks, watches, etc.
