Variable Performance Pumps
Model REDI-FLO2 / REDI-FLO4


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. Unlike most variable frequency drives, the Redi-Flo VFD is compatible with either 120V or 230V single-phase, AC input power. The operator can simply change the power cord to accommodate the different voltages. The Redi-Flo VFD can also be purchased without the carring case for use in dedicated applications.

Features
  • Precise Flow Control — The push button control pad provides greater control over the pump’s discharge flow rate for better accuracy and precision during sampling.
  • Wide Performance Range — Instead of operating according to one performance curve, the Redi-Flo VFD allows for coverage of a range of performances and can function at any point of operation within that range.
  • 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.
  • Dual Input Power Capability — Either 120V or 230V, single-phase AC input power is accommodated simply by changing the power cord.
  • Dual Functionality — The Redi-Flo VFD can be easily switched to operate either the Redi-Flo2® pump or the Redi-Flo4® Variable Performance Pumps.
  • Enclosure — The Redi-Flo VFD NEMA 4 enclosure is designed for outdoor duty and is resistant to damage as a result of incidental exposure to rain or splashing water.

How it works
The Redi-Flo2® Variable Performance Pump combines state-of-the-art technology into a light, compact and yet powerful submersible pump for precise, accurate and reproducible groundwater sampling. Designed for long-term reliability in dedicated monitoring wells, the Redi-Flo2® provides optimal sample quality with either traditional purging prior to sampling, or low draw-down passive sampling when operated with the new Redi-Flo VFD.

The Redi-Flo4® Variable Performance Pumps are submersibles constructed of virgin Teflon® and stainless steel to handle the rigors of contaminated groundwater monitoring and continuous operation in remediation applications. The Redi-Flo4® Variable Performance Pumps are designed to operate in 4 inch and larger wells to depths of 524 feet. The Redi-Flo4® pumps have a built-in check valve to prevent back-flow in the well after the pump is shut down. A user-friendly cable guard aids in the ease of variable length motor lead installation.
