Corrosion-resistant magnetic pump is Shanghai Amada company to introduce Japanese technology, and absorbed the international shield professional design and manufacture of advanced technology, by our R & D personnel to digest and innovate new shielding pump, improved on the basis of the original shield core technology to improve Fluid movement, improve the efficiency of more than 10%, the current reduced by 8%, the overall performance indicators have reached a new level. TPN shield pump is a motor and pump integrated structure of the pump, only static seal (rather than shaft seal), so be completely leak-free. Because of its low noise motor itself, combined with the shield pump low failure rate, high reliability, and low maintenance costs won the majority of users, but also to enhance the supply of high-quality pumps on the Chinese market. Products are widely used in petrochemical, medicine, food, textile, nuclear power, military and municipal water supply and drainage industry, building fire pressure, especially for vibration, noise, energy-saving leak-free places, such as key projects, pump room central air-conditioning and so on . Can also be used to transport pressure and temperature does not produce crystallization and solidification of the liquid, such as highly corrosive, highly toxic, volatile, radioactive and other media. Especially for the human body and the environment harmful and unsafe liquids and precious liquids. 1. The use of cost comparison: Shielded pump generally only 3 years to provide bearings, sleeve + thrust plate can be. 2. Flammable and explosive conditions: the use of mechanical seal of the petrochemical pump, seal principle of the closure of the mirror ring in high-speed rotation of the formation of liquid film, the machine seal cooling. There is a leak security risk. Shielding pump machine explosion-proof, completely leak-free. Explosion-proof grade DIIBT3, DIIBT4, protection class: IP54, IP55, more suitable for flammable and explosive conditions. 3. Petrochemical process pump According to API610 standard, according to the machine seal standard API682 in PLAN11 / PLAN11 +52 program comparison: import pressure is too large, resulting in PLAN11 machine seal service life is short. PLAN11 +52 program led to the procurement cost is too large. The selection of shielding pump can be designed according to user requirements pressure, do not have to consider the import pressure. Features: The basic type of electric shield pump, pump body mounted directly on the motor flange. Use parameters: Emissions: up to 1080m3 / H full head: up to 150m Motor power: up to 220kw temperature up to 380 degrees
