Introduction of the 4HS submersible pumps range 4HS is a 4” high speed centrifugal submersible pump for clean water composed by: high speed three phase asynchronous motor with wet rotor and canned type resin filled stator. Built-in inverter on board driven by a dedicated control module (CM) positioned outside the well.

4″ submersible pumps powered by renewable energy sources. 4HS MultiPower pumps can be powered by AC or DC with a wide range of operating voltage (90 – 265 VAC / 90 – 400 VDC). This means that 4HS MP pumps can be connected to solar panels, batteries, wind turbine and a diesel generator.

Multistage pump made of AISI 304 stainless steel. Inverter allows 4HS to: Change pump speed to maintain set-pressure re-gardless of water demand. Thus, the pump is oper-ated only when and as needed without wasting energy, and extending pump life. Starts and stops pump gently, thus reducing peak absorption, mechanical stress.

The 4HS is our range of high-frequency, high-performance borehole pumps – electric multi-stage submersible pumps designed for reliable water extraction across various applications.

4HS MultiPower pumps (4HS MP), powered by renewable energy sources, is a new range coming from the 4HS pumps with built-in inverter. 4HS MultiPower pumps can be powered by AC or DC with a wide range of operating voltage (90 – 265 VAC / 90 – 400 VDC).
