Zusammenfassung:PROBLEM TO BE SOLVED: To reduce pressure loss from a vicinity of a pump outlet by injecting liquid lubricant between an inner wall and high viscosity material in the vicinity of the pump outlet when high viscosity material such as sludge cake is pumped through piping. SOLUTION: A vicinity of the pump outlet in which the high viscosity material is delivered to the piping 3 consists of an outlet member 2. The outlet member 2 built in the pump is provided with a slit 2a (injection nozzle) injecting liquid lubricant such as water and paste between the high viscosity material and inner circumference wall surface in the vicinity of the pump outlet. The slit 2a is formed in a circumference direction. COPYRIGHT: (C)2006,JPO&NCIPI
