PURPOSE: An impeller for a spurt pump and an underwater spurt pump having the same are provided to easily pump up high-viscosity sludge containing foreign material or solid substances under the water and smoothly carry the sludge. CONSTITUTION: An impeller for a spurt pump comprises partitions(110,120) respectively on both ends, a shaft coupling hole(130) which is formed in the center of a partition to connect a shaft, an inlet port(140) which is formed in the center of the other partition to let fluid in, and a blade part(160) which is installed between the partitions to let fluid in through the inlet port and out in the direction perpendicular to the shaft. The blade part is formed in a spiral shape which gradually gets larger from the front end to the rear end with respect to the inlet port.
