Geotech PFAS-Free Portable Bladder Pumps

The PFAS-Free Portable Bladder Pump is designed specifically for sampling Per- and Poly-fluoroalkyl chemicals such as perflourooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in groundwater. The PFAS-Free Portable Bladder Pump is made with PFAS-free materials such as 316 stainless steel, high-density polyethylene (HDPE), and Buna-Nitrile to provide representative water samples. The single turn release head and quick change bladders allow for quick, in-the-field bladder changes and easy decontamination.

The PFAS-Free Portable Bladder Pump is proven to not contribute any PFAS substances to sample. Complete pump, tubing and safety cable have been soak tested and laboratory analyzed under "EPA 537 Modified" method. The samples from those tests showed non-detect for all 25 PFAS analytes.

Portable Bladder Pump Drop Tube Assembly

Geotech's optional drop tube intake system allows you to easily relocate the bladder pump intake way beyond the depth limitations of the pump. As long as the pump remains submerged, you can effectively and economically low flow sample from the well's screened section.
