Reliable water supply – on grid power or solar.
4HS is a submersible well pump for boreholes, water supply, irrigation and pressure boosting. With integrated frequency control, the pump adapts to actual demand, delivering constant pressure, lower energy use and safer operation – whether the system runs on the grid, solar power or both.
Key benefits
All-in-one pump
The permanent magnet motor and variable frequency drive are integrated into the pump, reducing the need for external equipment.
Solar power or regular electricity
The pump runs on both direct and alternating current: 90–400 VDC or 90–265 VAC.
Flexible choice of energy source
Can be connected to solar panels, the grid, batteries, wind power or a generator.
Automatic use of available energy
The pump adapts its performance to the energy source and the power available.
Steady, stable water pressure
When used with a pressure sensor, the pump adjusts its speed to water demand and maintains the desired pressure.
Energy-efficient permanent magnet motor
High motor efficiency and demand-driven speed deliver lower energy consumption than traditional on/off operation.
Soft start and stop
Frequency control reduces inrush current, pressure surges and mechanical stress on the pump and piping.
Built-in protection
Electronic monitoring and protection functions support safer pump operation and a lower risk of damage.
Robust construction
Multistage pump and permanent magnet motor in AISI 304 stainless steel, designed for installation in 4" wells.
Wide capacity range
Models with flow rates up to 14 m³/h and heads up to 230 meters, depending on the model.
Smart monitoring options
Operating data, alarms and settings can be accessed locally or via communication solutions, depending on the equipment selected.
Automatic switching between solar and grid
With the optional HMA, the system can switch automatically between solar power and the grid or a generator.
Connectivity & options
How the system connects, is controlled and monitored.
Bluetooth SMART
Local connection for easy configuration and service.
Wi-Fi / GSM
Remote monitoring and alerts via the internet or mobile network.
