Geotech PVC 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 250 feet (76.2 meters) with minimal agitation for the best representative samples.
- True low flow capability for less agitation
- Economical alternative to stainless steel
- Proprietary resin grade virgin PTFE bladder for long life
- Dedicated or portable turnkey systems
- Designed for wells as small as 2" (5 cm)
- Screened intake extends bladder life
- Optional Drop-Tube assembly available for sampling from greater depths
- GEO1.66PVC36
Durable PVC construction for a great value in a high volume pump.
For 2" (5 cm) wells or larger. - GEO1.66PVC18
The same as above but for lower pump volume requirements.
