Stainless steel magnetic pump for chemical plant

CQ light stainless steel magnetic pump (referred to as magnetic pump) is a new type of pump that applies modern magnetic principles and uses the magnetic force of permanent magnets to transmit actual torque without contact. When it is in rotation, the magnetic lines of force pass through the isolation sleeve to drive the inner rotor (that is, the inner magnetic steel) assembly and the impeller to rotate synchronously. Since the medium is enclosed in the static isolation sleeve, the purpose of pumping the medium without leakage can be completely solved. A new type of industrial pump with a full seal, no leakage, no pollution, high efficiency, and energy saving is designed to avoid the leakage of the shaft seal of the mechanical transmission pump.


Essential details


Structure: Single-stage Pump


Liquid: Acid Alkali Liquid

Model Number: CQ

Customized support: OEM, ODM


  • CQ light stainless steel magnetic pump is a new type of industrial pump with a full seal, no leakage, no pollution, high efficiency, and energy saving;
  • The pump body, impeller, diaphragm, pump shaft, inner rotor, isolation sleeve, and other overcurrent components are all made of high-quality stainless steel or special materials for precision casting;
  • The magnet is made of ferrite magnet, which has good magnetic properties, high-temperature resistance, and no demagnetization;
  • The moving ring and sliding bearing are made of graphite, PTFE, and other materials with high wear resistance and temperature resistance, which can effectively ensure the service life of the pump;
  • The seal adopts a closed static seal, which completely solves the leakage of the medium;
  • No need for independent lubrication and cooling water, reducing energy consumption;
  • The direct-connected back-pull design does not need to disassemble the pipeline, and the maintenance is convenient;
  • Horizontal installation, compact structure, small footprint, low vibration, low noise, and particularly stable operation;
  •  The external magnet is directly connected with the rotating shaft of the motor and adopts a direct-connected type, which has the advantages of simple structure, no need for centering, high transmission efficiency, low noise, and small vibration.


Widely used in petroleum, chemical, alkali production, smelting, rare earth, pesticides, dyes, medicine, papermaking, electroplating, electrolysis, radio, chemical foil, scientific research institutions, national defense industry, and other production processes to transport corrosive liquids, especially suitable for flammable, Explosive, volatile, toxic, high temperature, strong alkali, organic solvent and the transportation of precious liquids.
