    Product Overview:
    CQ type magnetic drive pump (abbreviated as magnetic pump) is a product that applies the working principle of permanent magnet coupling to centrifugal pumps, with reasonable design, advanced technology, good sealing performance, not easy to leak, and corrosion resistance.

    Second, the main features:
    The magnetic pump replaces the dynamic seal with a static seal, so that the pump's overcurrent parts are in a sealed state, which solves the disadvantages of other pumps' mechanical seals such as easy running, easy to run, and easy to drip. The magnetic pump uses corrosion-resistant, high-strength engineering plastics, jade ceramics, and stainless steel as manufacturing materials, so it has good corrosion resistance.
    Product use:
    Magnetic pump has compact structure, beautiful appearance, small volume, low noise, reliable operation and convenient use and maintenance. Can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film photofinishing, scientific research institutions, defense industry and other units to pump acid, lye, oil, rare precious liquid, venom, volatile liquid, and supporting equipment for circulating water Matching filter. It is an ideal pump for conveying leaky, flammable and explosive liquids.

    Conditions of use:

    1.Using temperature ≤80 ℃

    Installation and use

    1. The magnetic pump should be installed horizontally and should not be erected. The plastic pump body must not bear the weight of the pipeline. For vertical installation with special requirements, the motor must face upward.
    2. When the pumping liquid level is higher than the pump shaft centerline, open the suction pipe valve before starting. If the pumping liquid level is lower than the pump shaft take-up line, the pipe must be equipped with a bottom valve.
    3. The pump should be checked before use. The motor blades must be flexible to rotate, no jamming and noisy sounds, and all fasteners must be fastened.
    4. Check whether the motor rotation direction is consistent with the magnetic pump steering mark.
    5. After the motor starts, slowly open the discharge valve. After the pump enters the normal working state, adjust the discharge valve to the required opening.
    6. Before the pump stops working, close the discharge valve first, and then close the valve of the suction pipe.
    Seven, precautions for use
    1. Because the cooling and lubrication of the magnetic pump bearings rely on the conveyed medium, no-load operation is prohibited, and at the same time, no-load operation is caused when the power is restarted after a power failure in the middle of the work.
    2. If the conveyed medium contains solid particles, a filter must be added to the pump inlet: if it contains ferromagnetic particles, a magnetic filter must be added.
    3. The ambient temperature of the pump in use should be less than 40 C, and the temperature rise of the motor must not exceed 75 C.
    4. The conveyed medium and its temperature should be within the allowable range of the pump material. The operating temperature of engineering plastic pumps is <60 C, and the operating temperature of metal pumps is <100 C. Liquid containing hard particles and fibers.
    5. For the medium that is easy to precipitate and crystallize, the transport liquid should be cleaned immediately after use to drain the liquid accumulated in the pump.
    6. After 500 hours of operation of the magnetic pump, the wear and inertia of the bearing and the end ring should be disassembled. If the gap between the bearing and the sleeve is greater than 0.5 ~ 1mm, and the axial movement of the impeller is 1.5 ~ 2mm, the bearing and axial Moving ring.
