Grundfos Redi-Flo2® and Variable Frequency Drive

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. 

• 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
• 1.8-inch diameter.
• Flow rates range from 30 LPM to 100 mL/min.
• Portable solid state converter, eliminating the need for control valves.
• Continuous flow.
• Portable or dedicated configurations available.

The Grundfos Redi-Flo2® is quoted as part of a sampling sustem with the Redi-Flo VFD (Variable Frequency Drive). 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.  The 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.
