Emery has been deeply engaged in the groundwater monitoring industry for many years, routinely coordinating with numerous third-party projects involving testing, site investigations, and environmental operations and maintenance, and has observed that… Common pain points across the industry:

Traditional deep-water sampling causes significant disturbance, and once the water sample comes into contact with air… VOCs Highly volatile, leading to distorted water quality data;

The deep-well sampling system suffers from insufficient head, and the aging equipment has a high failure rate.

The sampled water does not meet national standards, and the test reports are repeatedly failing review.

Customer’s Selection of Groundwater Samplers

Some time ago, a client of a site remediation company approached Emory and shared… The challenging issues of on-site sampling:

1. Most projects involve sampling deep groundwater; conventional peristaltic pumps and bucket‑type samplers cause significant disturbance, and once the water samples are exposed to air, substantial losses of volatile organic compounds occur, leading to large deviations in the analytical results.

2. Moreover, conventional airbag pumps on the market only have 60 Mi Yangcheng: The deep wells are completely unusable, the equipment is cumbersome to operate, and the entire process of well cleaning and sampling takes a very long time, resulting in extremely low fieldwork efficiency.

In response to the issues raised by the customer, we directly recommended the company’s… AML919 Groundwater air‑bag pump sampler —— Specifically designed for compliant, non‑intrusive groundwater sampling, it fits perfectly. HJ 1019-2019 、 HJ 164-2020 Dual national standard requirements.

AML919 Core Advantages

Air-pump driven, with zero contact between the water sample and air throughout the entire process. , relying on the airbag to squeeze and pump out the water, completely Eliminate water body disturbance. ， VOCs The volatilization loss rate is lower than 0.5% , the recovery rate of volatile organic compounds is as high as 98% , thereby preserving the original water quality of the groundwater to the greatest extent possible.

Standard head 70 Rice ( Head can be customized, enabling measurement even in deep wells. ), far exceeding the standard models in the industry, and can also be customized to 300 Sampling at a depth of meters, It can easily adapt to all types of deep-well operating conditions. 。

The customer immediately raised practical concerns: “ The underground well environment is complex, with abundant sediment and corrosive water—how durable is the equipment? Is it easy for beginners to get started? ”

In this regard, customers need not worry at all.

AML919 The pump body adopts 316 Made of stainless steel and equipped with a corrosion-resistant PTFE sampling line, Acid- and alkali-resistant, sediment‑resistant, and suitable for a wide range of complex water qualities found at contaminated sites, landfills, and conventional monitoring wells. ；

The device is equipped with an intelligent controller. , the entire device is lightweight and portable , a single operator can independently complete the entire process—from descending into the well to collecting samples—without requiring multi-person coordination;

Meanwhile, AML919 Quick‑connect piping design, Quick disassembly and assembly make on-site maintenance in the field extremely convenient. 。

▷ In addition, The entire equipment sampling process is conducted in a closed system. , effectively preventing cross-contamination of water samples, Sampled data can be recorded and stored synchronously. , with end-to-end traceability, it easily handles on-site inspections by environmental authorities and eliminates, at the source, the issue of report rejections caused by non‑compliant sampling practices.

High customer satisfaction with follow-up surveys.

After a month of field trials, the customer proactively provided positive feedback:

“ Change into AML919 Since then, we’ve completely resolved our long-standing sampling challenges: water samples retain their pristine integrity, test results are both precise and stable, and all reports pass inspection on the first submission. Even deep-well sampling is effortless—one person can handle the job, doubling field‑work efficiency. This air‑bag pump is fully compatible with all of our project‑specific operating conditions. ”

Emery, grounded in the real-world operating conditions of domestic groundwater monitoring, refuses to simply copy imported high‑priced equipment. AML919 The air‑bag pump sampler combines high accuracy, high head, and excellent cost‑effectiveness, making it widely applicable in soil and groundwater investigations, environmental impact assessment monitoring, routine groundwater inspections, and emergency sampling at contaminated sites.

Reject perturbation sampling, reject data distortion. Select AML919 Groundwater bladder pump sampler: compliant sampling, pristine water‑sample integrity, and worry‑free operation even in deep wells—ensuring that every groundwater testing result is accurate and reliable.
