Pulsator irrigation is the most innovative development in micro irrigation. The pulsator combines the advantages of pressure compensation, the low volume flow of an emitter and the increased wetted diameter of a sprayer.

Low volume flow reduces system cost (mains and submains are smaller in diameter) and pumping cost. The pulsator is ideal for all fruit trees and can be used on any size and shape of field.

Pulsators are small plastic, hydraulic devices used in micro irrigation systems to reduce emitter and system flow rates to very low levels for higher efficiencies.

The pulsators have a built in dripper with a discharge of 4-8 L/hr that feeds an integral silicon sleeve chamber. This acts as a miniature pulsating pump generating hundreds of pulses per hour and emitting the water (see picture). The silicon sleeve remains closed when the water pressure drops with the termination of the irrigation and prevents the water in the system from draining. Pressure compensating pulsators are also available for use on sloping terrain.

Thus, they can convert a low continuous flow into an instantaneous pressurised emission of water in short pulses. They are attached to emitters one for each micro sprinkler or sprayer and one for 20-70 drippers accordingly.
