Geotech Bladder Pumps

Together with the USGS, Geotech designed the original bladder pump for groundwater quality and pollution monitoring. They can pump to the surface from as deep as 1000 feet (305 meters) with minimal agitation for the best representative samples.

Bladder Pump Models

  • A) GEO1.66SS36

    Made from SS for maximum durability. Highest volume rate for a low flow pump. For 2" (5 cm) wells or larger.

  • B) GEO01.66SS18

    The same as above but for lower pump volume requirements.

  • C) GEO.85SS24

    Made from high-grade SS for maximum durability. Extra slim design provides excellent performance for its size.

  • D) GEO.675SS

    Our smallest bladder pump, fits in any well .75" (1.9 cm) or larger. Made with the same polished stainless steel as our other top-of-the-line pumps.
