The Grundfos Redi-Flo 3 feature an all new high efficiency permanent-magnet motor that not only delivers an ultra-high starting torque, but also provides internal protection against pump dry-run, over and under voltage, plus overload and over-temperature safety. To review all the control advantages of a Redi-Flo3 see the atached brochure With the Grundfos Redi-Flo3 environmental pump you have complete control. Amazing! Or add a digital flow meter and you have your Redi-Flo3 stop pumping after the gallons you require were pumped.
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. With the combination of integrated electronics and along with optional CU 300 control box and R100 remote, the user has communication with the SQE-NE pump through the standard power leads. Redi-Flo3 pumps use an advanced electronically controlled "smart motor".
This wall mounted system maintains a constant pressure within the maximum pump performance in spite of varying water consumption.The Grundfos SQE-NE Redi-Flo3 pump is the most versital and easy to install environmental remediation pump on the market today. The Grundfos CU 321 is a constant pressure control system designed for use with 4' larger Grundfos SP pumps and motors. IO 351 The IO 351 is a module for exchange of digital. The CU 352 has application-optimised software for adapting the system to the application in question. The control panel enables manual setting and change of parameters such as setpoint. The CU 352 features a colour display, ten buttons and two indicator lights.1.1 Description The system maintains a constant pressure within the maximum pump performance in spite of a varying water consumption.
