Introduction
The Sample Pro 3/4” Portable MicroPurge Pump, (
Figure 1
) is the first pump de-
signed specifically to meet the practical needs of sampling small diameter wells: easy
to adjust to low-flow purging rates and easy to decontaminate between sampling
points. Decon is made easier by the pump having fewer parts, disassembly without
tools, and quick-change, disposable bladders. The Portable MicroPurge Pump is com-
pact and can pump from a 5-gallon bucket. The pump is operated by compressed gas
and a bladder pump control unit, and is ideally used with the MicroPurge basics
models MP10 and MP15 controllers. The compressed gas is on the outside of the
bladder and the pumped liquid is on the inside of the bladder, so there is no contact
between the sample and the gas.
