Spray heads are the workhorse of most irrigation systems.
At Hunter Industries, the durable design of irrigation products is at the coreof what we do and all of our products are built with innovation in mind.
When Hunter developed the Pro-Spray line of products, it was a challenge to trulyengineer the best spray body in the industry.
With that challenge in mind, Hunter developed the Pro-Spray and pressureregulated PRS30 and PRS40.
Let me take you on a tour of our product verification lab where you'll see howstrong these products are and how we prepare them for the toughest site conditions.
Hunter has a multi-million dollar test lab where we test every product wemake and put them throughevery possible performance conditionto ensure Hunter products perform in every real world condition.
Next I'm going to take you through a series of tests to compare the Pro-Spraywith other bodies.
We'll go through burst test,surge test,flush-cap test and cap-leak test.
First, let's go to the burst test and test our Pro-Spray along with othercompetitors' spray bodies.
The burst test is exactly what it sounds like - seeing how much pressure a spray bodycan take before it literally explodes.
To do this test,we cap the body off at the nozzle so no pressure can escape.
Then we fill a bladder tank with water.
Behind that tank, we have a nitrogen pressure tank that'll push the water upinto the body.
The pressure we're pushing into the body is measured by a gaugeand on release, the gauge marks the burst point.
Let's start with the Pro-Spray.
We put it into the chamber and start adding pressure.
200, 300, 400, 600and finally a burst at 650.
You can really see the water exploding out at high pressure!Next, we test the top selling body we callCompetitor 1.
Ready? 200, 300 and burst at only 300 PSI.
This body has a large hole at 300 PSI.
Next, we'll test Competitor 2,their top of the line spray body.
Ready? 200, 300 andburst at only 350 PSI.
Another break and at only half the pressurethe Pro-Spray body can handle.
Let's inspect the spray bodies.
Hunter's tough ABS plastic and molding process leaves only a small fracture woundwith a burst all the way up to 650 PSI.
The competitor bodies have large cracks that burst into wide holes due to theirinferior plastic and molding procedure.
These bodies burst at only 300 and 350 PSI.
Next is the surge test.
This test emulates the harsh demands of winterizationas well as surge pressure going through the spray bodies.
In the surge test, we thread the body onto a riser.
This time we fill a bladder with waterand surge water and air at 100 PSI straight through the body and out thenozzle.
This test is done twice at 10 cycles or until the body fails.
We tested the 4", 6" and 12" pop-up models.
Let's take a lookat just a few of the results.
Here's the 6" Pro-Spray going through the test.
Wow! You can hear the screeching water as it's pushed through the body so quickly.
First 10 cycles, no failure.
Second 10 cycles, still no failure.
The Pro-Spray has successfully gone through 20 cycles of 100 PSI watersurge test.
Check out the Hunter 12" Pro-Spray going through the same test.
Hunter performs as expected and easily handles all 20 cycles.
Now let's look at how some of the competitor models did in the test.
Here's what happened with competitor 1's 4" spray body.
Ready? Go! Boom! Competitor 1 flew right apart on the first cycle!You can really see the whole body justblew apart straight into the air.
The quick surge of 100 PSI just destroys the body on the first cycle.
How did competitor 2's 12" spray body hold up?Here we go.
In the first set of cycle, we notice the riser sticking.
Let's push it back down and let it go through the next cycle.
Once again, the riser sticks after each surge and needs to be physically reset.
It made it through 20 cycles,but not without a sticking riser.
Let's inspect these spray bodies to see what's happening.
On Competitor 2,the wiper seal has been mangled and distorted.
With the seal in this mangled condition, the body will stay popped up and willbe damaged by elements or routine landscape maintenance and we'll need areplacement.
When we look at the Hunter Pro-Spray,the innovative co-molded wiper seal has no signs of damage even after 20cycles.
The Pro-Spray is built tough to withstand any demand.
It's time to do some field tests around installation of bodies.
With Pro-Spray bodies, Hunter took everything into accountincluding the routine task of flushing the spray body.
The Pro-Spray flush caps are directional to allow you to control the large streamof watertowards the location you want.
Simply point the cap to where you want the water,flush the system,and there'll be no water mess at your location.
Now let's look at Competitor 1 and 2 caps.
It's just a hole with a tab.
There's no ability to control the water when flushing the system.
Water flies up and your'e left with a mess.
Hunter's Pro-Spray flush cap is another way that Hunter listens to ourcontractors in the field and constantly improves our products with the irrigationprofessional in mind.
It's time to do a cap leak test.
Let's see what happens when a cap is looseneddue topoor installation,environmental conditions, or vandalism.
In this test,spray bodies are mounted above ground running at 40 PSIto see how loose a cap can get before water starts leaking out.
First we tighten down the cap fully and mark the closed position.
All bodies are running as expected with no leaks.
We do our first test at a 1/4 turn.
Both Competitor 1 and Competitor 2 are already leaking.
Let's close them down and try this again.
This time we'll only do an 1/8 of a turn.
Once again, Competitor 1 and 2 are leaking,even with such a slight cap turn.
Let's take this test to the extreme and see what a full turn of the capwill do.
The Hunter Pro-Spray is still not leaking.
In fact, the Pro-Spray body can go a full turn and a half before signs of a leakappear.
With the Hunter Pro-Spray body and co-molded seal design, you can ensureif a cap is slightly loose in the field, the Pro-Spray won't let water leakaway.
The Hunter Pro-Spray is the best spray body in the irrigation industry.
Pro-Spray has a rugged body and cap,strong spring,and ratcheting riser,and a true engineering innovation - co-molded wiper seal.
The Pro-Spray should be the professional'sfirst choice in spray bodies.
