Durham GEO MBP Bladder Pumps

The GEO MBP Bladder Pump features Type 304 stainless steel construction and a special, flexible Teflon® bladder that permits very low-flow sampling rates from a few feet to more than 200' deep in wells and piezometers as small as 3⁄4" in size. The sample entry ports are dual screened and allow for easy point sampling in the water column. Economically priced pump and tubing make dedicated systems feasible.

When used with the Precision Dual-Range Controller, Pump will move from 5mL to nearly 2L per min. Precision electronic timing from 1–10 secs. for the air and exhaust, plus independent dual pressure regulators for exact control of the air pressure to the pump. Internal power source supplies 36 hrs. of continuous use.
