Geotech MP1 / Redi-Flo2 Pump

Variable-Speed Groundwater Sampling Pump

The Geotech Redi-Flo2 / Grundfos MP1 is a high-performance 2" electric submersible pump designed for groundwater purging and sampling from monitoring wells and boreholes.

Combined with the Geotech Variable Frequency Drive (VFD), pump speed can be precisely controlled to provide both high flow rates for efficient well purging and low flow rates for representative groundwater sampling. This wide operating range allows a single pump system to be used throughout the complete purge and sampling process.

Constructed from stainless steel and PTFE, the Redi-Flo2 is designed to maintain sample integrity while providing a robust and easily decontaminated solution for professional groundwater monitoring. Its compact 46 mm diameter allows deployment in 2" monitoring wells, with operation possible at depths of up to approximately 85 m.

The Redi-Flo2 can be configured as a portable sampling system or permanently installed for dedicated groundwater monitoring applications.
