HUNTER PRO-SPRAY
PRS 40 SPRAY SPRINKLER
The sprinkler shall be capable of covering a __________foot (meter) radius at _________ PSI (bars; kPa), with a full circle discharge rate of _______GPM (m3/hr; l/m).
The sprinkler shall be available with a 4-, 6-, or 12-inch (10-, 15-, or 30-cm) pop-up stroke, depending on the body specified, to bring the nozzle into a clean environment. The sprinkler shall have the option of either a factory-installed or field-installed drain check valve capable of checking up to 14 feet (4.3 m) in elevation change. The sprinkler shall come with a gray body cap to indicate the MPR40 product line for easy identification in the field except for conditions as when reclaimed water units are ordered. The sprinkler shall have available an optional, snap-on cap, molded in purple, a replacement body cap, molded in purple to indicate the use of reclaimed water, or a pre-installed molded purple body cap to indicate the use of reclaimed water.
The sprinkler shall have a standard pressure-regulating device as an integral part of the pop-up riser. This regulator will provide optimal distribution uniformity of the MP Rotator by maintaining a constant outlet pressure of 40 PSI with inlet pressures of up to 100 PSI, regardless of the rotator installed.
The body of the sprinkler shall be constructed of corrosion and UV-resistant, heavy-duty A.B.S. The riser of the sprinkler shall be constructed of abrasion and UV-resistant A.B.S. and shall be adjustable for pattern alignment. The riser shall be compatible with female threaded nozzles and shall have a stainless steel spring for positive retraction when irrigation is complete.
The sprinkler shall have a pressure-activated, multi-function, UV stable wiper seal that will clean debris from the pop-up stem while it retracts. The seal shall be molded around a rigid plastic ring to prevent seal deformation. This seal shall prevent the sprinkler from sticking in the up position and be capable of sealing the sprinkler riser stem to the sprinkler cap under normal operating pressures. The seal shall be removable from the cap for easy service and shall be replaceable.
The sprinkler shall have a factory-installed, removable flush cap with a pull-up tab that shall prevent debris from entering the sprinkler during installation and allow the system to be flushed before installing the nozzle. The flush cap shall have a directional flushing action that allows the water to escape only in one direction. The flush cap shall open as the stem extends and completely close when the stem is in the retracted position.
The sprinkler shall have an exposed surface diameter after installation of 2-1/4 inches (6 cm). The sprinkler shall have a 1/2-inch Female National Pipe Thread (FNPT) bottom inlet. In addition, the 6-inch (15 cm) and 12-inch (30 cm) sprinklers shall be available with a 1/2-inch FNPT side inlet. When specified with a factory-installed check valve, the 6-inch (15 cm) and 12-inch (30 cm) sprinklers will be supplied without the side inlet.
The sprinkler shall carry a five-year, exchange warranty (not prorated).
The sprinkler shall be manufactured by Hunter Industries Incorporated, San Marcos, California.
