The pumping equipment often used in the current pumping test mainly includes centrifugal pump, deep well pump, submersible pump, air compressor (air pump), etc..When selecting pumping equipment, it should consider whether the suction, lift, water output, etc. can meet the design requirements, and also consider whether the hole depth and aperture meet the requirements of water pump and other equipment. According to the general water output and regular pumping requirements, GT-CP50 centrifugal pump and GT-QDP-6 deep well pump can be selected as standard to complete the task of shallow hole and deep hole pumping respectively.

Pumping Description |
| Centrifugal water pump, water pump |
The suction range is less than 8m, the water output is large, and the use is simple and economical. |
| deep well pump |
In the large drop depth pumping test, the water output is generally large. The drilling diameter is required to be large, and the sand content in the water is strictly limited. |
| submersible pump |
The water output is generally large, the drilling diameter should be greater than 126mm, and the sand content in the water is strictly limited. |
| Air compressor |
The water level is buried deep, the drilling diameter is small, and the supporting equipment is large. |
