Geotech GeoSub 2

Geotech GeoSub 2 Groundwater Sampling Pump

The Geotech GeoSub 2 is a compact, high-performance groundwater sampling pump designed for controlled low-flow sampling from monitoring wells and boreholes. With adjustable flow control and sampling capability to depths greater than 60 m using the optional drop tube assembly, the GeoSub 2 is particularly suited to deep groundwater monitoring applications.

Designed for professional field use, the pump combines corrosion-resistant construction with a fully serviceable design. Many components can be replaced in the field, helping to minimise downtime and extend the operational life of the system.

Key Features

• Precision flow control – Adjustable flow rates from approximately 0.01 to 15L/min (subject to pumping head) for controlled low-flow groundwater sampling

• Deep sampling – Suitable for sampling to approximately 60 m depth to water, with greater depths possible using the optional drop tube assembly

• Compact design – Suitable for use in 2" monitoring wells and larger

• Durable construction – Corrosion-resistant materials for demanding field environments

• Field serviceable – Designed for straightforward maintenance with replaceable components

• Portable operation – Lightweight system designed for routine field deployment

• 110 V power supply – Suitable for operation from a compatible portable generator or site power supply

• Versatile sampling – Ideal for groundwater monitoring, contaminated land investigations and low-flow sampling programmes

• PFAS compatible - The stainless steel GeoSub2 is suitable for PFAS sampling in shallow and deep wells
