Grundfos Redi-Flo 3 Submersible Pump SQ, SQE & SQE-NE Grundfos

The Grundfos   Redi-Flo3 pump is the most versital and easy to install environmental remediation pump on the market today. Redi-Flo3 pumps use an advanced electronically controlled “smart motor”. With the combination of integrated electronics and along with optional CU 300 control box and R100 remote, the user has communication with the   pump through the standard power leads. This feature allows the use of multiple sensors, relays, or digital imput without the additional controls that cost a lot of money! Add a level transducer to the CU 300 and maintain the pumping level you program, speeding up or slowing down as needed. Amazing! Or add a digital flow meter and you have your Redi-Flo3 stop pumping after the gallons you require were pumped. With the Grundfos Redi-Flo3 environmental pump you have complete control.

Permanent-Magnet Motor
Redi-Flo3 pumps use the Grundfos “Smart Motor”,. This permanent-magnet motor is single phase input and with a 2-wire design makes installation easy. The combination of integrated microelectronics in the pump with the optional CU300 status box and R100 at the surface allows communication with the pump through
standard electrical motor power leads. No additional wires are required. This feature allows the direct use of multiple sensors, digital input and relays without adding extra control electronics and costs.

Advanced Electronics
By combining advanced electronics, permanentmagnet motors, and Grundfos’ own micro-frequency converter, we are now able to control and communicate with pumps in ways never before possible. A few of the features that come out of this combination are Fluid Level Control, Soft-Start and integrated Dry-Run Protection.

Status Box/R100 Infrared Remote
The optional Redi-Flo3 status box and R100 at the surface allows you to communicate with the pumps integrated electronics through the standard power leads. No additional wires are required! This feature provides the direct use of multiple sensors, digital input and relays without adding any extra electronics and cost. Pump status readout and parameter changes can easily be performed at the surface with the R100 or the Redi-Flo3 PC Tool.

Rugged Design
Redi-Flo3 pump design uses “floating”, impellers. Each impeller has its own tungsten carbide/ceramic bearing. This design and the environmentally tough 316 stainless steel and PVDF construction provide excellent wear resistance and solids handling capability.

Reliable Check Valves
Reliable built-in spring loaded check valves let you operate the pump in any position from vertical to horizontal.
