In 1990 PIP introduced its PIP Pulsators series 100 [US Patent 5,507,436].
The PIP Pulsators series 100 have been used since 1993 for humidity control, cooling and irrigation in greenhouses. In addition the PIP Pulsators series 100 are used for irrigating trees. In a test plot conducted by the University of Florida a drip irrigation system that was irrigating a 40-acre plot of citrus was converted to pulsating micro system in which the flow of each Pulsator was controlled by a 12-liter/hour dripper. The results show drastic production increase, additional net income per acre, and savings of large amounts of water. PIP is now producing different Pulsators with different innovated spraying devices for irrigating trees and bushes

PIP Pulsators series 100 and PIP Pulsators series 300 can be used with new strip jets that wet a strip of about 0.6 meters wide and 8 meters long. Each pulsating strip jet can be used to irrigate two trees.

The PIP Pulsators series 300 can be used also with different spraying devices that were previously used only to irrigate turf, and our PIP Pulsators series 500 can be assembled on a ½” nipple, eliminating the use of spikes and flexible tubes. Such Pulsators are especially useful for irrigating avocados, pecans and similar trees.

The PIP Pulsators, which can operate at super low flows of a dripper, are available with different Micro-Jets, Micro-Spinners, insert protected spinners, misters and sprayers.

The flow of a PIP Pulsating device can be controlled by a low flow of namely 12 l/h dripper, and operate with a rotating sprinkler that sprays water to a diameter of about 12 meters. Such pulsating sprinklers can be used for irrigation and for cooling different crops. In addition the PIP Pulsators can operate with a floating rotating sprinkler [US Patent 5,803,365]

During 1995 to 2005 several million pulsating strip jets type 100 were sold for frost protection and for cooling vineyards.

In 2006 PIP introduced its improved Pulsator Series 200 [US Patent 5,727,733] with a new innovated strip jet.

Since 2006, more than 500,000 of the new pulsating strips jets have been operating in areas such as California and in Chile for frost protection and for cooling vineyards.
The Pulsators series 200 and the Pulsators series 300 are used also for cooling and for frost protection of apples, blueberries, and similar crops.

The PIP Pulsators are also being used for cooling poultry and other livestock.

In addition to the Pulsators, which are used for agriculture applications, PIP is producing also Pulsators for irrigating turf. Our latest developments include pop-ups, and pulsating pop-up sprayers and sprinklers with a flexible stem, and a new innovated drip system in which a single drip lateral wets an area of about 12 meters wide. These innovative products are now being tested in different locations.
