When precision, portability, and purity are non-negotiable, field professionals turn to tools that deliver uncompromising results. The Geotech GeoPump™ Peristaltic Pump is one such tool—engineered specifically for the demands of shallow groundwater and surface water sampling. Compact yet powerful, this pump is a trusted choice across environmental, geotechnical, and hydrological applications.
Designed for Sample Integrity
At the heart of the GeoPump’s appeal is its mechanical peristalsis operation—a method that ensures fluids come into contact with tubing only, not the internal pump mechanism. This critical design feature eliminates the need for decontaminating the pump between samples, significantly reducing cross-contamination risk and boosting efficiency in the field.
Whether you’re sampling for VOCs, metals, or general water quality parameters, maintaining sample integrity is vital. The GeoPump’s design helps ensure that what you collect in the field is a true representation of the subsurface environment.
Versatile Power and Field Flexibility
One of the GeoPump’s standout features is its dual-power capability. It operates seamlessly on:
- 12–18V DC power (from a vehicle or field battery)
- 90–260V AC power (for lab or indoor use)
Each unit comes with long power cords—8 feet for AC and 15 feet for DC—giving you reach and flexibility in diverse field setups.
Series I vs. Series II: Choose the Power You Need
GeoPump Series I
- Single pumping station
- Variable speed: 60 to 350 RPM
