Geopump™ Peristaltic Pumps
A peristaltic pump often is a good choice for obtaining samples collected from wells at a depth of 29 ft. or less.*
The Geotech GeoPump™ is a portable, peristaltic-style pump, engineered for collecting shallow groundwater and surface water samples. The pump is designed to operate seamlessly on both 12V DC or 120VAC power sources, making it an ideal tool for fieldwork and equally efficient for lab applications. The GeoPump's unique design prioritizes sample integrity, significantly reducing the risk of cross-contamination. Fluids being sampled interact exclusively with the tubing and not the pump mechanism, effectively eliminating the need for decontamination of pump components between sampling points.

The GeoPump operates by mechanical peristalsis — a rotating cam compresses flexible tubing in sequence, creating a gentle pumping action that never contacts the sample fluid. This design ensures complete sample integrity.
SERIES I Geopump™ Peristaltic Pumps are available in AC only, DC only, or AC/DC combination. These units have one pumping station which can be piggy-backed for multi-station pumping. They have variable speeds ranging from 60 RPM to 350 RPM.
SERIES II Geopump™ Peristaltic Pumps are available in AC only, DC only, or 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 30 to 300 RPM and the second station 60 to 600 RPM.
