Which pump should be used for transporting materials at a boiling point of 180 degrees, with high viscosity, in a gauge pressure condition?
Thread Content
Material transfer in the distillation system of our workshop. The impeller shaft sleeve of magnetic pump is prone to wear. Grafite bearings in shielded pumps are prone to wear, and cavitation in the impeller is severe; in other mechanically sealed pumps, the sealing O-rings are easily damaged. Everyone says that pump is good.
Could you consider using a cam rotor pump or gear pump for transportation? You could also try a hose pump or something similar.
Could you provide detailed process operating conditions? Personally, I think a positive outcome might be achieved by using a positive-displacement pump in such an environment; however, it’s necessary to examine your data to be sure.
