Basic knowledge about self-priming magnetic pump

The self-priming magnetic pump is a new type of pump that applies the principles of modern magnetism and uses the magnetic drive of permanent magnets to achieve non-contact torque transmission. When the motor drives the outer rotor (ie, outer magnetic steel) assembly to rotate, it passes through the magnetic field. Acting magnetic lines of force pass through the isolating sleeve to drive the inner rotor (ie, inner magnetic steel) assembly and the impeller to rotate synchronously. Since the medium is enclosed in the stationary isolating sleeve, the purpose of pumping the medium without leakage is achieved, and the shaft seal leakage of the mechanical transmission pump is solved. , And designed a new type of industrial pump that is fully sealed, leak-free and pollution-free.
The self-priming magnetic pump is an ideal pump for avoiding running, emitting, dripping and leaking in the chemical process, eliminating environmental pollution, creating a “leak-free workshop” and “leak-free factory”, and achieving safe and civilized production. It is widely used in the production process of petroleum, chemical, pharmaceutical, printing and dyeing, electroplating, food, environmental. protection and other enterprises to transport corrosive liquids without iron filings and impurities. It is suitable for the transportation of flammable, explosive, volatile, toxic and precious liquids.

In the petrochemical industry, more and more manufacturers require a leak-free process environment for the medium they transport. In some occasions, such as transporting hot oil or media with particles (such as sewage treatment), and in the chemical production process , It is more urgent to choose the ideal non-leakage pump type.
The self-priming magnetic pump isolation sleeve assembly adopts three-layer reinforced isolation. The liquid contact layer is made of perfluoroplastic one-time high temperature molding, which has strong corrosion resistance; the middle layer is a stainless steel sleeve reinforcement layer. This design makes the isolation sleeve higher mechanical strength and better pressure resistance; the outer layer is reinforced The sleeve is made of carbon fiber reinforced plastic. This material has no magnetic loss and high pressure. In case the external magnet contacts the reinforced sleeve due to external force or other reasons, it will not produce sparks and maintain a high level of safety performance. High-power fluorine plastic magnetic pump is a good choice for transporting strongly corrosive, high-concentration, leaky, flammable, and explosive liquids instead of imported magnetic pumps.
