Magnetic drive pumps are sealless pumps that use a coaxial magnetic coupling to transmit torque to an impeller. A standard electric motor drives a set of permanent magnets that are mounted on a carrier or drive assembly. In turn, the magnets drive the inner rotor and provide the no-slip or synchronous capability of the torque coupling. There are two basic types of magnetic drive pumps: rotating driven…

Magnetic coupling is a new kind of coupling,which connects motor and machine by permanent magnetic force.They work in the sealless magnetic drive pumps,which transporting volatile,flammable,explosive and toxic solutions with no leakage. The appearance of Magnetic coupling solved thoroughly the leak problems existed in dynamic sealing of certain mechanical devices. Magnetic coupling are widely used…

Magnetic couplings improve the reliability, safety and efficiency of polyurethane processing by eliminating the need for drive shaft seals in the metering pump. Mechanical shaft seals, which separate the drive motor from chemicals in the metering pump, deteriorate over time and cause leaks. Magnetic couplings enclose the drive shaft in an airtight housing. There are no mechanical seals. Permanent…
