PURPOSE: An auxiliary suctioning device for a drain pump and a drain pump for a pumping station are provided to generate vibration with a vortex generated around an inlet of a drain pump, thereby controlling the generation of deposits on the bottom of a water collecting tank. CONSTITUTION: An auxiliary suctioning device for a drain pump comprises a guide unit(21) and an elastic supporting unit. The guide unit is arranged in an inlet side of a delivery pipe in which a drain pump is installed in inside to discharge water flowing into a water collecting tank. The guide unit is interfered with a flow of a fluid generated by the suctioning force of the drain pump, thereby generating vibration. The elastic supporting unit supports the guide unit to be spaced from the bottom of the water collecting tank and elastically supports the guide unit so that deposits on the bottom of the water collecting tank flows by the vibration of the guide unit. The elastic supporting unit comprises a plurality of supporters(30) installed in the lower part of the guide unit by being spaced from each other.
