Information about magnetic pump
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 shaft and stationary shaft. Rotating shaft magnetic drive pumps are usually made of metal and include a pressurized recirculation circuit to help prevent vaporization of the liquid required to lubricate the bearings. Stationary shaft magnetic drive pumps typically use non-metallic components such as ceramics and plastics and are best suited for light to medium duty applications.
Magnetic pumps are capable of pumping a variety of liquids. Some devices are designed to move abrasive materials, acids, adhesives, chemicals, concrete and grout, coolants, hazardous materials, liquid metal, or lubricants. Other devices are rated for combustible, corrosive, high viscosity, or high temperature media. Magnetic drive pumps are also used to move gasoline, diesel fuel, and oil; ground water, potable water, salt water, and wastewater; sewage, sludge, slurry and ash slurry; gas and air; powders, solids, and rendering wastes; and a variety of liquids and liquids with solids.
