Selection of mechanical seal circulation pump
Thread Content
For the seal of the reaction vessel, a circulating magnetic pump is currently being used. The reaction vessel has strict requirements regarding metal particles; the metal particles generated by the bearings of the circulating magnetic pump end up in the seal fluid, causing the level of metal particles in the final product of the reaction vessel to exceed acceptable limits. Are there any alternative pumps that can be used to minimize the generation of metal particles? It’s not necessary to use a magnetic pump. The maximum pressure in the reactor is 4 megapascals
At the front end of the circulation pump, a diaphragm pump is used to generate pressure; the circulation pump is responsible for transporting the sealing fluid. The pressure produced by the diaphragm pump is pulsatory, which makes it difficult to control the pressure on the mechanical seal, so a buffer tank has been added
