Case Study: Well Water Sampling from Narrow-Diameter Well Casings

Three common problems that customers with small-diameter, high-flow well water sampling often encounter:

1. How to conduct sampling when the well opening diameter is narrow?

The well casing diameter is only 50 mm. Previous well water sampling pumps could not be lowered into the well at all, which was time-consuming and labor-intensive.

The unique advantage of AIMOLI AML918: its ultra-small diameter design of only 45 mm allows it to easily enter various narrow well casings.

However, do not underestimate the small size of AML918. Its flow rate can reach 0.1~12 liters/minute, and it can be precisely adjusted. Whether it is low-flow volatile organic compound sampling or high-flow well purging operations, AML918 can handle it with ease.

2. Is the sampling depth sufficient for deep well water sampling?

The customer’s monitoring wells are mainly deep wells, with a water level depth of ≥60 meters. Ordinary sampling pumps usually cannot reach this depth.

The standard configuration of AIMOLI AML918 provides a lifting height of 70 meters, and even deeper depths can be customized, perfectly solving the problem of insufficient sampling depth.

In addition, the AML918 pump body is made of 316 stainless steel, with extremely strong corrosion resistance. Even in harsh environments with high salt and high alkalinity, it can operate stably for a long time.

Previously, a customer had a monitoring point by the seaside where the corrosion was extremely severe. The ordinary stainless steel pump they purchased broke down after only a few months of use. After purchasing AIMOLI AML918, this problem no longer occurred.

3. Are the well water sampling pump and sampling process compliant, and are the data accurate?

Regarding this point, you do not need to worry at all. AIMOLI AML918 fully complies with the HJ1019-2019 and HJ164-2020 standards.

Not only that, AML918 is also equipped with an intelligent control system that can monitor flow rate and lifting height in real time and automatically adjust operating parameters.

Moreover, the operation of the AML918 well water sampling pump is extremely simple. New users can independently operate it after only 10 minutes of training.

Key Point: AIMOLI Well Water Sampling Pump — Precision So Advanced That Competitors Are Urgently Trying to Catch Up!

In the end, the customer purchased 10 units of AML918 well water sampling pumps.

The customer called back and said:

“After using the new pumps to test 5 wells, the workload that used to require 3 people to complete in one day can now be finished by 1 person in just 3 hours! The efficiency improvement is incredibly fast!”
