The QED (Quality Environmental Equipment) Bladder Pump is a specialized groundwater sampling tool commonly used in environmental monitoring and sampling projects.

It is designed to collect representative groundwater samples from monitoring wells for analysis of contaminants.

While QED bladder pump is a choice of many users, Spectra Scientific Bladder Pump is another alternative industry-leader.

The bladder pump operates on a pneumatic (air-driven) principle, where compressed air is used to drive the pump and lift groundwater to the surface without introducing additional water from the surrounding aquifer.

Key Features & Benefits

  1. Low-Flow Sampling: The bladder pump is often used for low flow groundwater sampling, a technique that minimizes disturbance to the well and surrounding aquifer while providing accurate and representative samples.

  2. No Groundwater Contamination: The use of compressed air to drive the pump prevents direct contact between the pump and the sampled groundwater, reducing the risk of cross-contamination.

  3. Minimal Purging: Unlike traditional methods that require extensive well purging to remove stagnant water, the bladder pump's design allows for efficient sampling with minimal purging.

  4. Stainless Steel Construction: Many bladder pump models are constructed from stainless steel, making them durable and suitable for a wide range of sampling applications, including those involving potentially corrosive or harsh substances.

  5. Easy to Clean and Decontaminate: The bladder pump is relatively easy to clean and decontaminate between sampling events, ensuring the integrity of subsequent samples.

  6. Field-Portable: The pump is designed to be portable and field-friendly, allowing for efficient deployment in various environmental settings.

  7. Customizable: The bladder pump comes in various sizes and configurations to accommodate different well diameters and sampling requirements.

It's important to note that technology and product offerings can evolve, so you should always consult the most recent product documentation and guidelines from the manufacturer to ensure you have the latest and most accurate information about their bladder pump models, operating procedures, and maintenance recommendations.
