Shielded pump is a leak free pump composed of a shielded electric motor and a pump, mainly composed of pump body, impeller, stator, rotor, front and rear bearings, thrust disc, and other components. The stator and rotor are separated by non magnetic corrosion-resistant thin-walled sleeves, and the rotor is supported and immersed in the conveying medium by front and rear bearings, so there is no need for any type of dynamic seal to prevent external leakage of the conveyed medium. Overall, canned pumps are centrifugal sealed pumps. The shielded pump is absolutely leak free, and under negative pressure inside the pump, external gas will not be sucked in, making it particularly suitable for vacuum system operation; At the same time, it is suitable for high pressure, high melting point, and high and low temperature media. Shielded pump has a compact structure, small volume, and light weight; No cooling fan, low noise, wide range of use, reliable operation, and can provide a relatively good working environment
