Grundfos Rediflo 2 Submersible Pump

Description

The Grundfos Redi-Flo2® Electrical Submersible Pump provides smooth, uninterrupted water flow during groundwater sampling or conducting aquifer tests to depths down to 280 ft. Both high flow rates needed for purging and low flows recommended for sampling are achieved with the same pump.
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 Redi-Flo VFD (Variable Frequency Drive).

Features

Purging and sampling with the same pump is extremely efficient.
The unique design and superior materials allow for easy operation, decontamination and maintenance as well as disassembly and re-assembly.
All replacement and maintenance parts for the Grundfos Redi-Flo2® are immediately available at Geotech Environmental Equipment, Inc. a certified Grundfos Master Distributor.

Maximum Current (SFA): 5.5 amps
Motor Protection: Thermal overload –Thermik Geratebau, Series SY6 (176°F/80°C)
Current Overload: Incorporated into Redi-Flo VFD (9.0A for 10 seconds)

Grundfos Rediflo VFD 120V Pump Controller

Description

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.

Features

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.
