Stone Age Nozzles

Root Cutting

The Warthog cuts a hole in a pine 1x8 in less than a minute, when jetted for 14 gpm at 4,000 psi. So there is no doubt that a waterjet alone can cutroots. But in real sewers other factors are important - like nozzle positioning, technique, and sewer diameter. Do not expect to cut 2 in. diameter roots! The Warthog has cut roots up to 1/4 in. diameter, or masses of smaller roots at joints. Bigger roots require water pressures as much as 8,000 psi.

WS 084 Centralizer

The WS 084 Centralizer adds length to prevent the WS-1/2, or WS 1/2-J from reversing direction causing a serious safety problem - in sewers up to 8 diameter. It also holds the front jet far enough from a plug for best results from the front jet.

Super Centralizer WG Models

The Super Centralizer places the Warthog closer to the sewer centerline, for more powerful cleaning of the top wall. It also keeps the nozzle back from blockage, allowing the powerful front jet to do its work. The Super Centralizer bolts to the standard centralizer.

Why Is The WARTHOG™ the Most Powerful
Jetting Nozzle Available


The Warthog's rotating jets follow a helical path down the pipe wall, much like the threads on a bolt. So the entire surface can be cleaned with as few as two powerful jets. The result is streak-free cleaning that passes the most demanding inspection. With stationary jets, the only way to
avoid streaks is to use more jets. The more jets in a nozzle; the less power is available for each.

Unlike other rotating jet sewer nozzles, the Warthog'sTM viscous fluid governor slows rotation to about 10 MPH along the wall, preserving jet quality and maximizing cleaning power. Un-governed rotating nozzles can spin as fast as 10,000 rpm. At that speed, the jets are moving nearly 360 MPH along the wall of a 12 inch diameter line. It's too fast, and destroys jet quality and hitting power.

When water flows through a hose, pressure is lost due to friction. As a result most jetters lose 20% and 40% of their power due to hose pressure drop. The effect is easily demonstrated by pumping at maximum throttle, with the hose end restrained, and no nozzle. The pump discharge pressure will be between 400 and 1200 psi - a direct measure of how much pressure is lost due only to flow through your hose. Jet power is directly proportional to pressure.

Jetting of the sewer nozzle is very important for delivery of jet power, because its orifices control the flow and pressures at which the jetting pump will operate. When we jet a Warthog nozzle, we run a computer analysis to be sure we're supplying the most powerful possible jetting.

That's why we ask how much flow the customer's pump puts out, at what pressure, as well as hose diameter and length.

The computer calculates pressure drop in the hose and in the Warthog nozzle, then calculates jet sizes. With this information, you can be sure that the Warthog will deliver the maximum possible jetting power.


Mineral or Corrosion Scale Removal

Mineral deposits or corrosion scale present a particularly difficult cleaning challenge, requiring direct impingement of the waterjet on the sewer wall. The job is accomplished by jetting through the line to the next manhole, then changing the jetting. The usual jets are plugged and two at 90° are used while the hose is retracted. The extra 90° ports can be added to Warthog Model WH and WG heads at a nominal charge. Some-times it is necessary to use higher pressure pumps than normal for sewer cleaning. The Model WH, operated at 8,000 psi pressure is frequently used for de-scaling.

Power

This thoroughly-engineered sewer nozzle s power is the result of fewer, more powerful jets, rotated at con-trolled speed. Every Warthog Nozzle sold is computer-jetted specifically for the customer s pump and hose combination to deliver the maximum possible waterjet power to the walls of the pipe or sewer. It s proven to be effective removing grease, roots, sand, silt, and debris from sewers.

Economy

Warthog users say that it is the only jetting nozzle used on their trucks. It uses less water and completes the job faster than other nozzles. Why spend money on others

Durability

Warthog Nozzles are built from corrosion-resistant stainless steel alloys, and the centralizer is zinc-plated carbon steel. StoneAge offers every individual part for replacement purposes. So the Warthog can be maintained, and re-built for many years. A complete Operator s Manual with parts lists,drawings and maintenance procedures is provided with every nozzle, to help the user get the most out of his nozzle.

Jet Quality

Warthog Nozzles use the StoneAge Attack Tip. Thanks to high efficiency nozzle design and unique 7-step manufacturing process, these are the best quality, longest lasting tips we have found. The flow straightener corrects power-robbing turbulence, insuring excellent jet quality. StoneAge tests show that the hardened stainless steel Attack Tip can even outlast tungsten carbide jets.
