توضیحات
4HS is a range of 4” electric submersible pumps for well applications, featuring:
– Three-phase, water-filled, permanent magnet synchronous motor with encapsulated resin stator, fully constructed of AISI 304 stainless steel.
– Built-in integrated inverter controlled by CM control module.
– Multistage pump made of AISI 304 stainless steel.
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.
