Airbag pump is a low flow rate, low disturbance groundwater flushing and sampling equipment, suitable for the collection of various types, especially VOC pollutant samples.

The airbag pump controller is equipped with a small air compressor that provides a pneumatic source, eliminating the need to transport bulky and noisy compressors. It can meet the requirements of working conditions with a static water level within 80 meters. If the water level is deep, a booster controller can be equipped to allow the airbag pump to sample at a water level of up to 300 meters. To achieve a deeper sampling depth, the airbag pump can also be equipped with a drop pipe component to allow deeper groundwater samples to enter the airbag pump. In order to ensure low disturbance to groundwater, the airbag pump can also choose a multifunctional water level gauge well depth gauge (discharge water level gauge). When the discharge of groundwater level during the sampling process exceeds the set requirements, the sampling can be automatically stopped and wait for the water level to recover.
