The Geotech peristaltic pump (GeoPump 2) is designed for single and multi-stage pressure or vacuum pumping of liquids for field or laboratory use. Since the GeoPump can operate to a depth of 27 feet (8m) at sea level, it is ideally suited for sample removal from shallow wells and all surface water sources.
The GeoPump operates by mechanical peristalsis, therefore the sample only comes in contact with the tubing. This allows for sample integrity as well as easy cleaning and tubing replacement. Tubing can also be lowered to a specific depth without curling or floating on the surface of the water with the use of an optional stainless steel tubing weight.
