Tygon Tubing

Grundfos Variable Frequency Drive

Quick Overview

The Redi-Flo Variable Frequency Drive (VFD) is designed to operate and protect the Redi-Flo2® and the RediFlo4™ Variable Performance Pumps. With the push of a button, an operator can precisely control the discharge flow rate from the pump from 50 GPM (189 LPM) to 100 milliliters per minute, to depths down to 524 feet (160m).

* Required Fields




  • Precise Flow Control - The push button control pad provides greater control over the discharge flow rate for better accuracy and precision during sampling.
  • Wide Performance Range - Not just one performance curve, the Redi-Flo VFD covers a range of performances and can function at any point of operation within that range.
  • Dual Input Power Capability - Either 120V or 230V, single-phase AC input power is accommodated simply by changing the power cord terminations.
  • Dual Functionality - Easily switched to operate either the Redi-Flo2® or the Redi-Flo4™ Variable Performance Pumps.
  • NEMA 4R Enclosure - The NEMA 4R enclosure is designed for outdoor duty and is resistant to damage as a result of incidental exposure to rain.
  • Optimized Volts ⁄ Frequency Pattern - The Redi-Flo VFD V/Hz pattern is specially optimized to allow the most efficient operation of Redi-Flo2® and Redi-Flo4™ variable performance pumps.
  • Motor Protection - The Redi-Flo VFD will protect the Redi-Flo Variable Performance Pumps from adverse motor conditions such as, over- and under-voltage, over-current, and groundfault.
