• Precise Flow Control — The ten-turnpotentiometer provides greater control over thepump’s discharge flow rate for better accuracyand precision during sampling.

• Wide Performance Range — Instead ofoperating according to one performance curve,the Redi-Flo VFD allows for coverage of arange of performances and can function at anypoint of operation within that range.

• Motor Protection — The Redi-Flo VFD willprotect the Redi-Flo Variable PerformancePumps from adverse motor conditions such as,over-and-under-voltage, over-current, andgroundfault.

• Dual Input Power Capability — Either 120V or 230V, single-phase AC input power isaccommodated simply by changing the powercord terminations.

• Dual Functionality — The Redi-Flo VFD can be easily switched to operate either theRedi-Flo2® pump or the Redi-Flo4™ VariablePerformance Pumps.

• Remote, Automatic Operation — The Redi-Flo VFD can be remotely operated andcontrolled by an external 4-20 mA signal from adevice like a pressure transducer or flow meter.With the use of a PID, along with a pressuretransducer or flow meter, the Redi-Flo VariablePerformance Pumps can maintain a constantdraw down within the well, or maintain aconstant flow rate from the pumps.

• Dry-Run Protection — The Redi-Flo VFD canbe configured to protect pump and motor fromexperiencing a prolonged “dry-run” condition.The drive can be automatically restarted after aspecified delay.

The Redi-Flo VariableFrequency Drive

Redi-Flo2 ® and Redi-Flo4™ VariablePerformance Pumps

The Redi-Flo2 ® VariablePerformance Pump combinesstate-of-the-art technologyinto a light, compact and yetpowerful submersible pumpfor precise, accurate andreproducible groundwatersampling. Designed for long-term reliability indedicated monitoring wells,the Redi-Flo2 ® providesoptimal sample quality witheither traditional purging prior to sampling, or lowdraw-down passive samplingwhen operated with the newRedi-Flo VFD.

Study after study has shownthe Redi-Flo2 ® VariablePerformance Pump is theideal sampling device forrepresentative groundwatersamples.

The Redi-Flo4™ VariablePerformance Pumps aresubmersibles constructedof virgin Teflon® andstainless steel to handlethe rigors of contaminatedgroundwater monitoringand continuous operationin remediation applications.The Redi-Flo4™ VariablePerformance Pumps aredesigned to operate in 4inch and larger wells todepths of 590 feet. TheRedi-Flo4™ pumps havea built-in check valve toprevent back-flow in thewell after the pump isshut down. A user-friendly cable guard aidsin the ease of variablelength motor leadinstallation.

Discharge/Pump Housing*corrosion-resistant with Female NPT

discharge pipe connection

Integral Check Valve(Redi-Flo4™ only)

offers reliable, jam-free back flow prevention

Guide Vane*increases pump efficiency by

providing optimal fluid movement

Impeller*long-wearing, corrosion-resistant with

a high strength-to-mass ratio; afabricated design allows for optimum

hydraulic performance

Spacer Ring and Wear Ring(Redi-Flo2 ® only)

placed at each impeller, eliminating vibration and maintains

pump efficiency

Seal Ring and Intermediate Bearing(Redi-Flo4™ only)

placed at each stage to support theshaft and maintain pump efficiency;constructed of 100% virgin Teflon®

Inlet Screen*non-corrosive inlet screen prevents

the impellers from clogging

*On these features, the material of constructionfor the Redi-Flo2® is 316 stainless steel, and

the Redi-Flo4™ is 304 stainless steel.

The Redi-Flo Variable FrequencyDrive (VFD) has been uniquelydesigned to operate and protectthe Redi-Flo2 ® VariablePerformance GroundwaterSampling Pump and the Redi-Flo4™ Variable PerformanceSampling/Remediation Pumps.Due to the revolutionaryelectronics within the Redi-FloVFD, the operator can easilychange between the Redi-Flo2 ®

Pump or the Redi-Flo4™ VariablePerformance Pumps by simplyturning a knob. With the turn ofanother knob, the operator canprecisely control the dischargeflow rate from the pump from amaximum of 50 gallons perminute to a minimum of 100milliliters per minute, to depths to 590 feet of head.

Unlike most variable frequencydrives, the Redi-Flo VFD iscompatible with either 120V or230V single-phase, AC inputpower. The operator can simplychange the terminations of thepower cord to accommodate thedifferent voltages.

The Redi-Flo VFD can also beoperated in the “Automatic Mode”in which the drive’s outputfrequency is directly related to a4-20 milliamp input signal.

The Redi-Flo4 ™ provides up to50 gallons per minute for purgingand remediation.

Smooth, continuous, uninterrupted dischargeflow rate is possible with the Redi-Flo2 ®.
