Frequency converter SMART FLOW S for pumps and home water systems

Product detailed description

Frequency converter SMART FLOW for pumps up to 8A, 1x230V, with output up to 1.1kW The SMART FLOW S frequency converter is an all-in-one, in-line control unit that maintains constant pressure in the system by regulating the pump speed. SMART FLOW is designed for deep well pumps, multistage self-priming pumps and submersible pumps By changing the motor speed of the pump, it maintains a constant, set water pressure. Automatic operating modes of the frequency converter protect the pump and reduce its load and number of starts. Connecting the pump with a frequency converter saves 30% to 60% of energy. Protective functions of the SMART FLOW S frequency converter Special dry-run protection technology without the need to install probes/sensors in the well Protection against overcurrent / overvoltage / undervoltage Short-circuit protection Protection against impeller blockage Overtemperature protection Overpressure protection Freeze protection Water leak warning Advantages of the SMART FLOW S frequency converter Energy efficiency. Compared to traditional water supply methods, a constant-pressure water supply system with a frequency converter saves up to 30%-60% of energy. Simple operation: Using the SMART FLOW frequency converter is very simple. All functions can be set with the push of a button, without the need for complicated setup. Longer pump service life when controlled via a frequency converter: The average torque and wear on the pump shaft are lower due to the reduced average rotation speed, extending the pump's service life. Thanks to the soft start and stop function, the frequency converter eliminates water hammer – a sudden pressure spike caused by rapid stopping or starting of the liquid flow. Quiet operation Use of the SMART FLOW S frequency converter The SmartFlow S frequency converter is used in all applications where constant water pressure needs to be maintained in the system. It is also used to control and protect the pump. In family homes, apartments, holiday homes for supplying water from a well, garden irrigation, and collecting and using rainwater. In agricultural operations for irrigating farmland and supplying water Pressure setting range 1 – 6 bar How the SMART FLOW S frequency converter works When a tap is opened or irrigation starts, the pressure in the system begins to drop. The frequency converter's control unit evaluates the situation via a pressure sensor and starts the pump. The pump speed is regulated to maintain constant pressure in the system even as demand changes. To put it simply, the frequency converter runs the pump at, for example, 17% at low demand, 57% at increased water demand, and 97% at high demand. The converter's current and dry-run protection are pre-set. The pump is stopped, started, and has its pressure increased or decreased quickly and easily by the frequency converter, whenever needed. The SMART FLOW S frequency converter is suitable for all systems where constant water pressure, pump control, and pump protection are required.
