Pump with variable-speed controller 4HS

centrifugalwaterwith asynchronous motor

All the advantages of built-in electronics An inverter allows 4HS to: Change pump speed to maintain set-pressure regardless of water demand. Consequently the pump is operated only when and as needed without wasting energy, thereby extending pump life. Starts and stops pump gently, thus reducing peak absorption, mechanical stress. Protects pump and drive from overload, undervoltage, surges, dry running and any abnormal conditions. Integrated on-board inverter avoids the use of expensive filters and shielded cables reducing electromagnetic emissions to a minimum. 4HS product range meets the needs of commercial and residential markets for water supply, water pressurisation and irrigation. Compared to conventional solutions, 4HS offers: Energy-saving operation. Quick and simplified application. System reliability. Construction characteristics and use of specific materials allow 4HS to be suitable for drinking water applications.
