Grundfos Rediflo VFD rental

Rent Grundfos Rediflo VFD 120V Pump Controller

The Redi-Flo Variable Frequency Drive is designed to operate and protect the Redi-Flo2® and the Redi-Flo4™ Variable Performance Pumps. With the push of a button, an operator can precisely control the discharge flow rate from the pump from 50 gallons per minute to 100 milliliters per minute, to depths down to 524 feet.

  • 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.
