A leakage free magnetic pump (referred to as a magnetic pump) is a new type of pump that applies modern magnetic principles and utilizes the magnetic transmission of permanent magnets to achieve contactless torque transmission. When the motor drives the outer rotor (i.e. the outer magnetic steel) assembly to rotate, the magnetic field passes through the isolation sleeve and drives the inner rotor (i.e. the inner magnetic steel) assembly and impeller to rotate synchronously. Due to the medium being enclosed in a static isolation sleeve, the purpose of leakage free pumping of the medium is achieved, completely solving the shaft seal leakage of mechanical transmission pumps. This new type of industrial pump is designed to be fully sealed, leak free, pollution-free, efficient and energy-saving, and its performance meets international standards. It can replace expensive imported chemical pumps.
2, Features of stainless steel magnetic pump:
1. Magnetic pump is a new type of industrial pump designed and developed according to the international standards of IS02858/GB5662/DIN24256, which is fully sealed, leak free, and pollution-free. Its technical indicators have reached the advanced level of similar products at home and abroad;
2. The pump body, impeller, and pump cover are designed with hydraulic components using fluid mechanics for modular design and precision casting. It has the characteristics of wide flow channel, high efficiency, good cavitation margin performance, small radial force, accurate size, smooth flow channel, and good interchangeability;
3. The magnet is made of ferrite, neodymium iron boron, and samarium cobalt, which have good magnetism, high temperature resistance, and do not demagnetize; Its magnetic energy product is 28 megagauss Otes, and its temperature tolerance limit is 350 ℃. Under conventional cooling conditions, its maximum operating temperature is limited to 260 ℃, which can avoid demagnetization to the greatest extent possible, resulting in a theoretical service life of up to 20 years for magnetic materials;
4. The shaft sleeve and sliding bearing are made of high wear-resistant materials such as silicon carbide, graphite, and PTFE, and lubrication grooves are set up to effectively ensure the service life of the pump;
5. No leakage, all sealing points adopt closed static sealing, driven by magnetic couplings, without the need for nitrogen sealing, safe, economical, and efficient, completely solving medium leakage;
6. No need for independent lubrication and cooling water, reducing energy consumption;
7. The international standard axial coupling rear pull design eliminates the need for dismantling pipes and facilitates maintenance;
8. Horizontal installation, low vibration, low noise, smooth operation, international standard design, interchangeable with standard centrifugal pumps, convenient for users to replace and use;
9. Transforming from coupling transmission to synchronous driving, there is no contact or friction. Low power consumption, high efficiency, and damping effect, reducing the impact of motor vibration on the pump and the impact of pump cavitation vibration on the motor;
