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.A ready to use product.The 4HS range of submersible pumps are suitable for drinking water applications and are designed to provide customers a readyto use product and come packaged in a kit, comprising:4HS pump including 2.5 mtr/8 foot flat cable lead (ACS-WRAS-KTM compliant).surface control module (CM).cable junction kit.pressure transducer 0-16 bar/0-250 psi.operating manual.
