The self-compensating dripper has a silicone membrane that works under pressure: that is, the membrane closes when the water pressure increases so that the volume of water that comes out does not increase, and thus always remains the same as the desired flow rate.

With this system we can better control the output of the water, and the possibility of making much longer lines while maintaining flow uniformity between the first branch and the last.

An advantage of the membrane is that it serves to get rid of the dirt that clogs the dripper, thanks to the movement of the diaphragm under the effect of pressure.

Self-compensating drippers, in order to regulate the pressure exerted by the water between 0.5 to 4 bar and achieve the desired flow rate (0.5 to 25 L/H), require a long-lasting silicone diaphragm or membrane.

The silicone membrane with special chemical and mechanical properties is responsible for keeping the output flow constant for the pressure range considered. The membrane is resistant to chemicals normally used in agriculture (fertilizers, herbicides, acids...) and supports a minimum value of pH2.
