Rotary Spray Nozzle: Can Increase Power for Your Pressure Washer.
 
 
Rotary Spray Nozzles

Once, when 100% of anything was reached, it used to be considered complete…at maximum capacity…whole. One-hundred percent of something was virtually all that something could give, get, have, obtain, sustain, offer, need, or otherwise. Somewhere in the last 20 years or so, the event of being 100% has morphed into a curious state of being able to be more. Physicists must have a time of it, but these days we are often asked to give 110% of ourselves… or exclaim we need 150% of something 150% of the time!

If anything can boast such a condition, it is the power a rotary spray nozzle can add to your pressure washer! Rotating spray nozzles can increase your pressure washer’s cleaning power by almost 200% more than a flat fan nozzle. (Forgive us, Einstein!)

Rotary spray nozzles are turbo charged by centrifugal force. The water comes across spinning! Including this circular motion to a 0° spray pattern adds up to twice the power of other nozzles. Before rotating spray nozzles, a 0° spray nozzle was the ultimate power obtained in a jet of water while pressure washing. Now, spray nozzles add to this power, with water alone, by spinning it, which literally acts like an added abrasive. A spray nozzle can strip paint, remove barnacles from marine vessels, knock gum off sidewalks, and clean off rust, graffiti, mud and clay, etc. from most surfaces in half the time of a regular power washer spray nozzle.

The difference in a rotary spray nozzle is the increased impact caused by centrifugal force. This causes a super intense strike against a surface and increases the efficiency of any pressure washer. Your cleaning time is cut in half just by the voracity—even though the spray pattern covers just 4-8 inches at a time.

All rotary nozzles have ¼” quick connects. The nozzles are ceramic, which are very resistant to abrasion. There are light-duty, medium, and heavy-duty heads. They are usually encased in plastic and need from 2,500 PSI (pounds per square inch), up to 5,000 PSI with 4 – 4.5 GPM (gallons per minute). There are also industrial heavy-duty stainless steel heads with ceramic nozzles that operate with 7,350 PSI and 5 GPM. That’s a lot of cleaning power!

Rotary spray nozzles have no gears or bearings to wear down. They have no teeth to jam or break. The only part that may show wear on a spray nozzle is the ceramic orifice and seat, or the threads may become damaged. Replacement parts for the nozzles are easy to get and they are quick repairs. You may also want to consider using a nozzle filter, which is purchased separately. These filters help keep debris from clogging / ruining a nozzle.

Rotary spray nozzles tips come in brass, aluminum, stainless steel, hardened stainless steel, ceramic, nylon, or plastic. Brass has a tendency to re-act badly to certain chemicals. You must be careful what you use. Brass can also be worn down if used with some abrasive materials. It is more susceptible to corrosion than nylon or plastic, too.

Nylon and plastic wear well, but the threads on these can be damaged more easily than brass. It can be damaged, mostly, by over-tightening. Some solvents can cause nylon or plastic to swell. There are plus’s and minus’s to both materials. Evaluate your needs and determine which is best for you.

Rotating spray nozzles must be started with care. With this kind of waterpower, you never want to be facing the rotating spray nozzle while it is, or even may, accidentally come on. Eye protection is extremely important while using a rotary spray nozzle. Once you get going, you may find you can get pretty wet on the job. Your next purchase can be a rotary nozzle shield that attaches easily to you nozzle!
