Geotech Geopump™ Peristaltic Pumps


The Geotech Geopump™ Series I and II Peristaltic Pumps are designed for single and multi-stage pressure or vacuum pumping of liquids. They operate by mechanical peristalsis, so the sample only comes in contact with the tubing. This allows for consistent sample integrity as well as easy cleaning and replacement.  The Geopump is ideally suited for field sample removal from shallow wells, all surface water sources and for laboratory use.
