Grundfos Redi-Flo 2″ Variable Frequency Drive (VFD) W/Case


The Redi-Flo Variable Frequency Drive (VFD) has been uniquely designed to operate and protect the Redi-Flo2® Variable Performance Groundwater Sampling Pump and the Redi-Flo4® Variable Performance Sampling / Remediation Pumps.

Due to the sophisticated electronics within the Redi-Flo VFD, the operator can easily change between the Redi-Flo2® Pump or the Redi-Flo4® Variable Performance Pumps by pressing a button.

With the pressing of another button, the operator can precisely control the discharge flow rate from the pump from a maximum of 50 gallons per minute to a minimum of 100 milliliters per minute, to depths to 524 feet of head.
