Grundfos Redi-Flo2® on GeoReel

Grundfos Redi-Flo2®

The Grundfos Redi-Flo2® Electrical Submersible Pump provides smooth, uninterrupted water flow during groundwater sampling or conducting aquifer tests to depths down to 280 ft. (85m). Both high flow rates needed for purging and low flows recommended for sampling are achieved with the same pump.
Designed for long-term reliability in dedicated monitoring wells, the Redi-Flo2® provides optimal sample quality with either traditional purging prior to sampling or low draw-down passive sampling when operated with the Redi-Flo VFD (Variable Frequency Drive).

  • Purging and sampling with the same pump is extremely efficient.
  • The unique design and superior materials allow for easy operation, decontamination and maintenance as well as disassembly and re-assembly.
  • All replacement and maintenance parts for the Grundfos Redi-Flo2® are immediately available at Geotech Environmental Equipment, Inc. a certified Grundfos Master Distributor.

Geotech VFD

Geotech Variable Frequency Drive

The Geotech Variable Frequency Drive (VFD) is designed to operate and protect the Redi-Flo2® pump. With the turn of a knob, an operator can precisely control the discharge flow rate from the pump from 8 GPM (30 LPM) to 100 milliliters per minute, to depths down to 280 feet (85m).
  • Precise Flow Control
    Turn the knob or use the push button control for greater control over the discharge flow rate for better accuracy and precision during sampling.
  • Wide Performance Range
    Not just one performance curve, the Geotech VFD covers a range of performances and can function at any point of operation within that range.
  • Choose Input Power
    Either 120V or 230V, single-phase AC input power is available.
  • NEMA 4x Enclosure
    The NEMA 4x enclosure is designed for outdoor duty and is resistant to damage as a result of incidental exposure to rain. Designed for wash down applications.
  • Optimized Volts ⁄ Frequency Pattern
    The Geotech VFD V/Hz pattern is specially optimized to allow the most efficient operation of the Redi-Flo2® variable performance pump.
  • Motor Protection
    The Geotech VFD will protect the Redi-Flo2® Variable Performance Pump from adverse motor conditions such as, over- and under-voltage, over-current, and groundfault.

Geosmart Electrical Pump
Dedicated Sampling Systems

Custom manufactured to your specifications, pumps are secured in place with your choice of well caps and tubing. Geosmart pumping systems save you installation time and virtually eliminate the potential of cross contamination as compared to portable systems. Consider the cost of routine equipment blanks, decontamination time, wear and tear on your equipment and then decide if Geosmart is right for you.

Why dedicated Geosmart Systems?

  • Installs in 10 minutes or less
    Systems are cut to length, pre-assembled and individually packaged for easy installation
  • More representative data
    Eliminates the risk of cross contamination and is
    an EPA approved method for VOC collection
  • Saves time!
    No need to decontaminate since you are not
    moving pumps from well to well
  • Low flow sample rates

Customize your Geosmart system to your application

  • Well caps for a variety of applications and budgets. Custom well cap and fitting options available upon request.
  • Tubing is available in a variety of sizes & materials: Polyethylene, FEP lined poly, FEP, PVC nylobraid
