Pump Selection

Variable speed allows 4HS to cover a wide range of water flow and heads with just a few models; selecting the proper pump model for an application will help maximize performance and overall efficiency. Use the diagram in the brochure to select the most suitable 4HS pump model for your application

Energy Saving

If the water demand decrease's, 4HS will reduce the speed (proportional to the frequency) to maintain constant pressure. As you can see from the chart, a speed reduction corresponds a significant decrease of the power consumption. For example, maintaining constant the 6 bar, if the speed drops from 4800 rpm to 4200 rpm, input power decreases from 1600W to 700W

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 pressurization and irrigation.

Compared to conventional solutions, 4HS offers:

Energy-saving operation, Quick and simplified application, System reliability

4HS pumps are made entirely of AISI 304 stainless steel to ensure the long life of their components

CM: Control Module mounted above-ground, manages the pump operation by changing pump speed to maintain the desired pressure in the system regardless of water demand. Simply connect the pressure transducer, supplied as standard, and perform a quick setup of the sensor to configure the pressure range for the system. During operation, the CM control unit continuously monitors the electrical, hydraulic and thermal parameters providing complete protection against surges, undervoltage, overload and dry running.

4HS Comes complete with a 2.5 meter flat cable from the motor

If the distance between the pump and power supply is longer that the supplied cable it is necessary to make a junction performed by the special kit provided

3 core cable for the power, size to be determined

Plus 2 core 1.0mm for the signaling cable

The cable selection for additional power cable must be calculated considering the maximum allowed power loss
