Description

The Grundfos CU 301 is an intelligent constant pressure pump control. The CU 301 works with the pump, controlling its speed, allowing you to receive the water you need while supplying it at a constant pressure. The SQE SmartFlo range works with SQE pumps available in 4 sizes: .5hp, .75hp, 1hp, and 1.5hp. Add our constant pressure kit with the pump and CU 301 controller to complete your system. Once installed the Grundfos SmartFlo system will constantly adapt pump performance to meet your water demands. Pump reliability is ensured as the controller continually monitors your system for problems, protecting from issues like low or high voltage and run-dry (stopping the pump from damage).

The SQE constant pressure system complete is one complete solution without the need of additional controls or wiring. The system is comprised of the CU 301 controller with the constant pressure kit (CPK). The system includes the CU 301 controller, 8 litre X-Trol water tank, pressure transducer, manifold, pressure gauge, and relief valve. All of these features, complete in one kit, guarantee to save time and money!
