2 points inter filament (1/4) diameter 12.5MM

Pressure range

1.0-1.7bar 380V (1300W)

1.4-2.8bar 220V/380V

2.0-3.0bar 220V/380V

2.1-3.5bar 220V/380V (1100W)

2.5-4.0bar 220V/380V

2.6-3.5bar 220V/380V (1100W)

3.5-5.0bar 380V (2200W)

Remarks

For example, if the pressure range is 1.5-2.2bar, the technical explanation is that the water pump will automatically start when the water pressure reaches 1.5bar, and stop working when the pressure reaches 2.2bar.
