Abstract
The present invention is a system and method for pumping a fluid using a high-speed, fluid evacuating pump in which the pump is operated by a battery powered hand drill, wherein a first embodiment of a pump design includes a rigid cylindrical draw tube with the intake placed at the bottom and an outlet disposed near the top, a gear assembly attached to the top of the pump to achieve proper impeller speeds required to reach the targeted fluid pumping volume, and a rigid and segmented driveshaft connected to the gear assembly to drive the impeller placed near the intake of the pump, wherein the driveshaft includes a plurality of solid segments and hollow segments threaded together to thereby decrease vibration of the driveshaft at high RPMs.
