THE CASE AGAINST: The Bladder Pump

摘要

Bladder pumps have historically been used for sampling at many contaminated sites across the US. Bladder pumps, I believe, had their purpose at one time. As far as submersible pumps, prior to the development of 2" centrifugal pumps and especially the 12-volt centrifugal pump, they were pretty much the only option other than a bailer. However, in my opinion, bladder pumps are old technology and there are numerous draw backs to using bladder pumps for low flow sampling.
