[Summary] Present device refers to cooling material compulsion circulation of pump and slurry inflow prevention equipment of sealing surface. Coolant compartment of coolant circulation in the internal sealing section, which formed in pump shaft's sleeve, and coolant compartment of coolant circulation in the external sealing section, which is formed in coolant compartment's sleeve surface, is formed in spiral circulation. And due to the pressure of coolant's helical circulation, frictional surface, which is formed in the sealing section from compressed substance, is smoothed. It protects sealing section's frictional surface with cooling effect in the coolant compartment and improves the function of sealing section.
