Sump groundwater pumping device with vacuum pump

摘要

The present invention is to provide a vacuum pumping tank that can directly apply a constant vacuum force individually to a plurality of heart wells inside the sump well to continuously increase the amount of water without the groundwater vein closure as a vacuum pump (2 Each pipe 35 is connected to the vacuum pumping tank 1 to which the pump is connected, and the groundwater 36 is introduced using a vacuum suction force, and then pumped into the sump 37 by a self-priming submersible pump 4. It is a catchment groundwater pumping device that has built-in vacuum pumping tank.
