4HS is a range of 4" electric submersible pumps for well applications:

• three phase water-filled asynchronous motor with encapsulated resin stator, fully constructed of AISI 304 stainless steel.
• built-in integrated inverter controlled by CM control module.
• mutlistage pump made of AISI 304 stainless steel.

An inverter allow 4HS to:

• change pump speed to maintain set-pressure regardless of water demand. Thus, the pump is operated only when and as needed without wasting energy, and extending pump life.
• starts and stops pump gently, thus reducing peak absorption, mechanical stress.
• protects pump and drive from overload, surges, under/over-voltage, dry running, and any abnormal conditions.

4HS product range matches applications in 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.
