GEOTECH (91351103) Geopump Peristaltic Pumps

The Geotech Geopump Series II (91351103) which often includes the hardwired AC power cord and EZ-Load 2 pump head) is a portable, high-performance peristaltic pump designed for sampling shallow groundwater and surface water. It is designed to handle rigorous field conditions, offering reliable, contamination-free sampling. Geotech Geopump Peristaltic Pumps are designed for versatile, high-performance groundwater sampling and fluid transfer. Key features include a suction lift of up to 27-29 feet (8-8.8 meters), variable speed controls (up to 600 RPM), and reversible flow for back-flushing. They offer exceptional field durability, support multi-station pumping, and use disposable tubing to prevent contamination. Designed for field or lab use, the Geotech Geopump Peristaltic Pumps offer single-stage pressure or vacuum pumping of liquids to depths of 27 feet (at sea level). They are ideally suited for sample removal from shallow wells and surface water sources.

They operate by mechanical peristalsis, so the sample only comes in contact with the tubing to ensure sample integrity, 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. Series I Geotech Geopump Peristaltic Pumps: Available in AC only, DC only, or an AC/DC combination. These units have one pumping station, which can be piggybacked for multi-station pumping. They have variable speeds ranging from 60 RPM to 350 RPM. Series II Geotech Geopump Peristaltic Pumps: 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 30 to 300 RPM and the second station 60 to 600 RPM.

Versatile Pumping: Available in single or two-station models, with the ability to "piggyback" heads for increased flow or multi-port sampling.
Contamination Control: Utilizes disposable, easy-load tubing, eliminating the need for decontamination between sites. 
Applications:
Groundwater Monitoring & Sampling: Specifically designed for low-flow sampling in shallow wells (typically up to 27–29 feet deep at sea level).
Surface Water Sampling: Ideal for collecting samples from rivers, lakes, ponds, lagoons, and ditches.
Laboratory Use: Used for single and multi-stage pressure or vacuum pumping of liquids in controlled environments.
Environmental Research: Employed for aquatic inventories, such as Environmental DNA (eDNA) sampling to detect rare or invasive species.
Gas Sampling Support: Can be used as a vacuum pump for inflating Tedlar bags when used with a Tedlar Inflation Box.
