The Grundfos Redi-Flo2 Pump is designed specifically for environmental groundwater purging and sampling of monitoring wells.  The Redi-Flo 2 is the only 2 inch pump that works down to 300 feet.  Use the Redi-Flo 2 pump for environmental sampling in 2 inch or larger wells.    The Grundfos Redi-Flo2 pump works great either as a portable sample/purge pump or in a dedicated system, Environmental Equipment & Supply builds both.  The Redi-Flo2 Variable Performance Pump combines state of the art technology into a compact powerful submersible pump for precise and reproducible groundwater purging and sampling.  The Grundfos VFD (variable frequency drive) is required for operating the Redi-Flo2 pump.  The VFD is available in 115 or 230 volt and comes in a case.  The Grundfos VFD allows the user to slow or speed up the pump as needed making precision sampling easy.  Purging and low flow sampling is easy.  For reliable results, count on the Grundfos Redi-Flo 2 for a smooth uniterrupted flow..
