Mini Bladder Pump System Enables Economic System Dedication
The DURHAM GEO MBP Mini Bladder Pump provides truly representative samples using the Low Flow sampling technique—a process where dedicated equipment is used to retrieve samples without performing conventional multiple-well volume purging prior to sampling. The low fluid volume per stroke minimizes turbidity concerns. Pump features Type 304 stainless steel construction and a special, flexible PTFE resin bladder that permits very low flow sampling rates from a few feet to more than 200 feet 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. Stainless steel body measures 1" dia. x 18"L.
Economically priced Mini Bladder Pump and Dual Bonded Tubing, No. 220253, sold separately, make dedicated systems feasible.
