The Grundfos Smartflo Kit includes - Selected Pump Assembly, Constant Pressure Kit (CU301 control box & 0-120 PSI pressure transducer), 2 gallon expansion tank and a underwater splice kit.
The Grundfos SQE SmartFlo constant pressure system input power is standard house 230V or 115V on select systems. The Grundfos SQE pump includes 2 power wires + 1 ground wire. The Grundfos SQE pump was designed to fit inside a 3" I.D. up to a 6" I.D. well casing (larger well casings require installing a pump sleeve). The Grundfos SQE pump is approved to operate horizontally with proper mounting. The Grundfos CU301 control center communicates with the Grundfos SQE pump at a higher frequency (similar to DSL) over the same two power wires to the Grundfos SQE pump reducing the need for additional wires. The Grundfos SQE pump soft starts reducing starting amp. surge and wire size requirements. The Grundfos SQE SmartFlo system maintains constant pressure throughout its pumping range simulating a city water supply. The Grundfos SQE SmartFlo pump system also includes over/under voltage protection, dry run protection. It is suitable for operation on a 1200 watt,115 or 230 volt invertor generator or a true sign wave inverter with correct voltage available. The Grundfos SQE SmartFlo system has a 2 year manufactures warranty and a proven track record over many years in the field.
The Grundfos SQE Smartflo system is simple to install making it DIY friendly. The Grundfos SQE pump uses only 2 hot wires to the pump instead of competitors 3 wires reducing the cost for a long length of wire. The Grundfos SQE Smartflo Kit is the only system you can still operate the pump without a controller. This is major advantage over competitors 3 phase systems because when they fail your pump CANNOT be operated without the controller that usually needs to be ordered. The Grundfos CU301 controller works with all Grundfos SQE Smartflo systems making it easy to stock avoiding stocking competitors multiple controllers for different size pumps.The Smartflo CU301 controller is also about half the price, weight and size of most competitors controllers.
NOTE: The Grundfos CU301 status box version 6 doesn’t allow for the pressure to be set higher than 75 PSI. This can be field adjusted with the appropriate remote control.
