Tank Washing Spray Nozzles

Tank washing nozzles can be used to clean, wash, and rinse every size container from small bottles and medium-sized drums to large railroad tankers. BETE has stationary tank cleaning nozzles, rotating tank cleaning nozzles, and tank cleaning machines.


What BETE nozzle series and types produce this spray pattern?

How is this spray pattern achieved through nozzle design?

Water emitting from slots in the spray head causes the spray head to rotate, providing a quick, uniform rinsing action in an omnidirectional 360 degree spray.

Water flow through a rotor in the Orbitor body driving a series of gears that cause spray jets on the nozzle head to rotate in a controlled fashion with an omnidirectional 360 degree pattern. The jets provide high impact force for cleaning large tanks with hard to clean residues.

Water shears off the turns of the spiral design to create concentric rings of spray, resulting in available spray angles of 270 or 180 degrees. Coverage is not as uniform as other tank wash nozzle types, but the TW series can fit through smaller tank openings due to its smaller physical size.

A manifold distributes water to several standard full cone nozzles with orientations positioned to achieve a full omnidirectional spray coverage.

Operating Specifications & Frequently Asked Questions for Tank Washing Nozzles

Typically, an omnidirectional spray pattern covers 360 degrees in all directions. Other patterns such as 270 and 180 degree spray angles are available for applications where only certain areas need coverage, for instance, in tanks with open tops where a standard tank wash nozzle would spray out the top.

Larger droplets carry more momentum for better cleaning performance, so recommended operating pressures are selected to balance large drop size and high emitting velocity.

We recommend Orbitors operate between 45 and 145 psi. All other tank wash nozzles work best in the 30 to 50 psi range, as higher operating pressures result in smaller droplets and decreased cleaning performance.

Ideal flow rate is most significantly influenced by the size of the tank. Larger tank diameters will require nozzles with higher flow rates. Nozzle data sheets have maximum recommended tank sizes based on nozzle model and operating pressure.

Tank washing nozzles are the only nozzles that provide omnidirectional 360 degree coverage suitable for washing all surfaces from floor to ceiling of a given bottle, drum, tank or enclosure.

It is important to keep in mind that internal obstructions within the tank such as mixers, agitators, baffles, etc. can cause “shadowing” from the tank wash nozzle, so hidden surfaces may not get cleaned properly. In these cases, it may be necessary to install multiple nozzles to ensure coverage on all surfaces.
