AIMOLI Bladder Pumps generally refer to the AML919 bladder pump groundwater sampler developed by AIMOLI (Hebei) Technology Co., Ltd.. It is a domestically produced professional device specifically designed for low-flow, high-precision groundwater sampling. Its core advantage lies in solving difficulties in deep-water sampling and preventing distortion in volatile organic compound (VOC) collection.
Core Specifications and Performance of AIMOLI Bladder Pumps
Maximum lifting depth (head):
The standard sampling depth is 70 meters. With proprietary ultra-high-pressure technology, it can be customized up to 300 meters, exceeding imported instruments by 10 meters and adapting to various high-pressure deep-well environments.
Sampling efficiency:
Water discharge begins within 3 minutes. The sampling flow rate ranges from 0.1–0.5 L/min, fully meeting low-flow sampling requirements.
Water quality monitoring:
Integrated portable 6-parameter water quality meter (pH, dissolved oxygen, ORP, conductivity, temperature, turbidity), enabling real-time on-site determination of well purging completion.
Material properties:
The bladder is made of PTFE (polytetrafluoroethylene), which is resistant to high temperature, high pressure, and strong acids/alkalis. This ensures no volatile loss and no cross-contamination of samples.
AIMOLI Bladder Pumps Main Application Scenarios
Groundwater VOC sampling:
Strictly complies with standards such as HJ1019-2019 and HJ164-2020, suitable for soil and groundwater volatile organic compound monitoring in contaminated sites.
Deep monitoring well operations:
Solves the problem of traditional imported bladder pumps failing to discharge water in wells deeper than 260 meters, and can replace bailers while reducing water disturbance.
Contaminated site investigation:
Widely used for non-destructive groundwater sampling and pollution source tracing in landfill leachate-impacted areas.
AIMOLI Bladder Pumps Product Advantages
This independently developed product has obtained more than 10 technical patents. It is suitable for monitoring wells of various diameters. It is already used as an enforcement instrument by the National Analysis and Testing Center of the Ministry of Ecology and Environment, environmental departments in 28 provinces and cities, and has been continuously used for three consecutive years as equipment in groundwater certification examinations.
