Pumping devices are essential for hydrogeological testing.

[0003] A recording device for hydrogeological pumping tests, with China's authorized announcement number CN217899414U, is provided. By setting a connecting base, in order to facilitate the adjustment of the working position of the equipment, the connecting base can slide left and right through the second threaded shaft. Then, when sliding, the connecting base can slide to a certain extent between the third threaded shaft and the second slider and the second connecting slide rail, thereby ensuring that the equipment can slide left and right and adjust the working position of the equipment. The connecting base and the second slide rod are slidably connected to ensure the stability of the equipment when sliding. Pumping tests are performed on the equipment at various positions, and then the recording work is performed by staff.
