Grundfos Redi-Flo VFD Converter

Variable Performance Pumping System

Magnify

Grundfos’ Redi-Flo Variable Frequency Drive (VFD) Converter is designed to protect and operate the RediFlo2 Sampling Pump and the Redi-Flo4 Sampling and Remediation Pump. Through the Redi-Flo VFD it is possible to switch between the Redi-Flo2 pump and the Redi-Flo4 variable performance pump with a button press. Another button provides the operator with the ability to control the discharge flow rate from a minimum of 100 mL/min to a maximum of 50 GPM, at depths up to 524 feet of head. The Redi-Flo VFD, unlike most variable frequency drives, is compatible with both 120V or 230V single-phase AC input power. To accommodate a given voltage the operator only needs to change the power cord.

The Redi-Flo VFD also protects enclosed Redi-Flo variable performance pumps from destructive motor conditions such as overcurrent, over-and-under-voltage, or a groundfault. The Redi-Flo VFD NEMA 4 enclosure is designed to survive outdoor use and protect its contents against incidental exposure to splashing water or rain.

Redi-Flo VFD orders can be placed with a carrying case for easy transportation of equipment to job sites, or without for dedicated installation.
