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

Pressure range

0.8-1.6bar (Suitable for 100W)

1.0-1.8bar (Suitable for 125W) (more commonly used)

1.2-2.0bar (Suitable for 125W)

1.5-2.2bar (Suitable for 250W/300W/371W) (more commonly used)

1.6-2.4bar (Suitable for 250W/300W/371W)

1.8-2.6bar (Suitable for 550W)

2.2-3.0bar (Suitable for 750W) (more commonly used)

2.8-3.5bar (Suitable for 750W/1100W)

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.
