Magnetic drive centrifugal pump (hereinafter referred to as magnetic pump) is the application of modern magnetism principle is the motor driven outer rotor (ie outer magnet) assembly rotation, the role of the magnetic field through the isolation sleeve to drive the inner rotor (ie, the inner magnet) The assembly rotates synchronously with the impeller. Since the medium is enclosed in a stationary isolation sleeve, the purpose of leak-free pumping medium is achieved, and the shaft seal leakage of the mechanical transmission pump is completely solved, and the new design of the fully sealed, leak-proof and pollution-free Industrial pumps. In addition, the magnetic pump is also the chemical process to eliminate running, running, dripping, leakage phenomenon, eliminate environmental pollution, and create "no leakage plant," "leak-free factory" to achieve safe and civilized production ideal pump. Widely used in petroleum, chemical, pharmaceutical, printing and dyeing, electroplating, food, environmental protection and other enterprises in the delivery of non-ferrous scrap corrosive liquids, especially for flammable, explosive, volatile, toxic and valuable liquid delivery. In the field of petrochemicals, more and more manufacturers require a leak-free process environment for their media. In some special cases, such as transporting hot oil or granular media (such as sewage treatment), and chemical production The process, the more urgent need to choose the ideal leak-free pump. MT-MSP series of high-temperature magnetic multi-stage pump and the magnetic separator pump with suspension products to solve the conventional magnetic pump has been unable to solve the transport high temperature (350 ℃) and with granular media technical problems, can be a direct substitute for machinery Transmission IH chemical pump. MT series of magnetic pumps after long-term productive continuous operation test, the user can be sure that they are using the most safest and most reliable pump. First, the principle of transmission Magnetic pump is the use of magnetic coupling principle of non-contact torque transmission torque of a new type of pump, when the motor drives the outer rotor rotates, driven by the magnetic field within the rotor and the impeller rotating synchronously To achieve the purpose of pumping liquid, it is a hermetically sealed, leak-free pump because the liquid is enclosed in a stationary isolation sleeve. Second, the characteristics of the abolition of the mechanical seal pump, mechanical seal completely eliminate the pump inevitable run, run, drip, leak of the disease, is the best choice for plant leakage. As the pump flow components selected stainless steel, engineering plastics to manufacture, so as to achieve the purpose of corrosion resistance. Pump magnetic coupling and pump body as a whole, so compact, easy maintenance, safety and energy saving. Pump magnetic coupling can drive motor overload protection. Third, the use of Magnetic pump with its full seal, no leakage, corrosion-resistant features, widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, film and television printing, defense and other departments used to pumping flammable, explosive, toxic And precious liquid, is to create a leak-proof, pollution-free civilized workshops, civilized factories ideal pump. Fourth, the working conditions of magnetic fluid pump medium density of not more than 1300kg / m3, the viscosity of not more than 30 × 10-6m3 / S of non-ferromagnetic and fiber-containing liquid. Conventional magnetic pump rated temperature for the pump body made of metal or F46 lining, the maximum operating temperature of 80 ℃, rated pressure of 1.6MPa; high temperature magnetic pump temperature ≤ 350 ℃; for the pump body is non-metallic, the maximum temperature is not Over 60 ℃, rated pressure of 0.6MPa. For the transmission medium density greater than 1600kg / m3 of liquid, magnetic couplings need to be designed. Magnetic pump bearings are transported by the lubrication medium cooling, drum magnetic pump is strictly prohibited no-load operation.
