Geotech Peristaltic Pump

Geotech Peristaltic Pump



Geotech's Peristaltic Pumps are designed to remove liquid samples from shallow wells and any surface water source by vacuum or pressure pumping through tubes. Available in AC, DC or AC/DC versions, they are equally suited for the field or laboratory.

The Geotech Peristaltic Pumps operate by mechanical peristalsis, so the sample only comes in contact with the tubing. This allows for sample integrity as well as easy cleaning and replacement. With the optional stainless steel tubing weight, tubing can be lowered to a specific depth without curling or floating on the surface of the water.


The Geotech Series I Peristaltic Pumps are available in AC only, DC only, or an AC/DC combination. These units have one pumping station which can be piggy-backed for multi-station pumping. They have variable speeds ranging from 60rpm to 350rpm.


The Geotech Series II Peristaltic Pumps are available in AC only, DC only, or an AC/DC combination. They have two pumping stations which can also be piggy-backed for multi- station pumping. The first pumping station has a variable speed of 30rpm to 300rpm and the second station 60rpm to 600rpm.
