For more detailed information including performance data, request Catalog 15, A Guide to Safe and Effective Tank Cleaning.
– An external air, electric or explosion-proof electric motor drives the nozzle hub where two to four high-impact solid stream sprays rotate and clean large tanks up to 80' (24.4 m) in diameter.
• Fluid-Driven Tank Wash Nozzles:– The liquid flow is all that is needed for rotation. Nozzles can
either be free spinning or rotating at nearly constant speed and can clean tanks up to 25' (7.6 m) in diameter.
Choose from a comprehensive selection of tank washers and nozzles in different sizes, materials, spray coverages, flow rates, pressures and connections.
For total tank cleaning automation, our turnkey AutoJet® Tank Cleaning System can be configured with any Spraying Systems Co. tank wash nozzle or tank washer. These systems include all the necessary pumps, motors, valves and washdown control panels to ensure optimal performance of the tank washer or tank wash nozzles and minimize the need for operator intervention.
• Motor-Driven Tank Washers:
This section provides an overview of our automated tank cleaning systems, tank washers and tank wash nozzles.
You’ll find clean-in-place and portable solutions to help automate rinsing, sanitizing, disinfecting and sterilizing tanks up to 80 ft. (24.4 m) in diameter.
Spray distance is usually measured in terms of tank diameter. However, you should also consider the tank
length and height. You may need to use more than one tank washer to clean the entire tank thoroughly.
Impact values are based on theoretical total impact formula:
Impact = .0526 x flow rate x =pressure
Selection and Optimization Tips
Automated tank cleaning offers many benefits: increased productivity, reduced maintenance time and labor costs, decreased chemical and water costs, improved worker safety and cleaner tanks.
Address These Factors First to Identify the Best Tank Wash Solution for your ApplicationResidueIs the substance sticky or easily cleaned? Can it be dissolved by the cleaning liquid? What is the level of impact required to dissolve it and wash it away?Level of Cleaning• Rinsing: Majority of residue is loosened and removed with water.• Cleaning: Remaining residue is loosened and removed with water and cleaning agent.• High impact cleaning: Utilizes the impact of the spray to break apart difficult and stubborn
residues and wash them away.• Sanitizing: Chemical agent is applied to all surfaces to kill microorganisms to an
acceptable level.• Disinfecting: Kills most bacteria with the exception of spores.• Sterilizing: Eliminates all forms of life.Cleaning Solution and Required Temperature of the Cleaning LiquidChemical additives are typically used to remove contaminants, improve tank wettability and reduce droplet formation. Heat can improve the cleaning action of many water-based detergent chemicals.Tank Size and Spray DistanceSpray distance is usually measured in terms of the tank diameter, however, it is important to consider the tank length and height. For example, if a tank is 20 ft. (6 m) in diameter and 40 ft. (12 m) long, use two tank washers that specify 20 ft. (6 m) or a single tank washer that can clean up to 40 ft. (12 m).Flow RateUse the lowest possible flow rate to achieve your cleaning objectives. The lower the flow, the less liquid required, less effluent for disposal and less energy consumed. A general guideline is to work with a minimum of 0.2 gal/min/ft2 (7 l/min/m2).A more moderate recommendation is 0.4 gal/min/ft2 (15 l/min/m2). This guideline generally applies to stationary nozzles where all the surfaces of the tank are sprayed at the same time. Nozzles that rotate usually contact part of the tank at one time, thus less flow rate is needed.Spray ImpactHard-to-clean residues require a higher level of impact than residues that are easily rinsed. It is difficult to determine the exact impact value of each tank wash nozzle.However, a general rule of thumb can help you increase the level of impact when determining the optimum cleaning requirements for your application. Increasing flow rate is more effective than increasing pressure. As the chart below shows, doubling the flow rate increases impact as much as 100%, while doubling pressure provides only 40% more impact.
spray PatternSolid stream sprays provide the greatest impact, followed by flat fan and full cone sprays. Typically, fixed spray nozzles with full cone sprays are used for gentle rinsing and washing. Fluid driven nozzles with flat fan sprays offer more impact and are commonly used for cleaning. High-pressure and motor-driven nozzles use solid streams for maximum impact.
spray coverage and obstructionsCleaning coverage provided by various spray angles ranges from 65° to 360° degrees. Multiple nozzles may be required if a spray cannot reach a part of the tank due to internal obstructions such as a mixer or agitator.
cleaning cycle durationMost cleaning cycles last from 10 to 30 minutes and include three to four stages: pre-rinse, which should remove 90% of the soil; cleaning; post-rinse and sanitizing.
nozzle Material and connection TypeFor most applications, stainless steel nozzles are used for their durability and ability to withstand high temperatures. For corrosive applications, nozzles made of polytetrafluoroethylene (PTFE) or polyvinylidene fluoride (PVDF) are preferred. For sanitary applications, standards may require materials, such as PTFE, and stringent design and mounting specifications.
Types of Tank cleaning nozzles
High-pressure(motor-driven)
Two to four nozzles rotate on a motor driven gear hub
Fluid-driven(reactionary force)
Rotational velocity increases as
pressure increases
Fluid-driven(constant speed)
Rotates at constant speed as pressure
fluctuates
Fixed(stationary)
Multiple orifice assemblies stay in position while
Ensure Efficient Delivery to Nozzles with Strainers and Lances
Line strainers are another critical component of your automated system. Particulates in the liquid can clog nozzles or stop rotation, which results in insufficient cleaning and potential product contamination. Filtering the liquid with line strainers prevents clogging and also extends the wear life of downstream equipment including nozzles and pumps.
For fine straining, woven wire mesh screens provide very small openings to strain particulates down to 200 mesh (74 microns). The mesh screen should be made of stainless steel for strength and corrosion resistance. The screen is critical to the operation of the strainer, and an extra screen should be kept on hand for each strainer installed.
Tank wash lances are more than just an installation component. Lances ensure efficient delivery of the liquid to the nozzle. We design and fabricate lances for any of our nozzles to ensure trouble-free system performance and offer single-source convenience.
Lances are available in different lengths for optimal positioning within the tank. In many cases, nozzles are positioned so the spray impacts directly on the heavily soiled areas or skim lines.

Integrate All System Components
To optimize cleaning performance all components – tank wash nozzles, pumps, motors, valves and strainers – should be integrated into an efficient system. Our sales engineers help solve tank cleaning application problems and integration issues on a daily basis. They are available for on-site, no-obligation consultation upon request.
For total tank cleaning automation, an AutoJet® Tank Cleaning System is an ideal solution. AutoJet Tank Cleaning Systems include pump/motor sets sized for best performance, inlet/outlet valves with pressure gauges and inlet strainers. Cycle timing control and chemical injection are optional features that enhance cleaning efficiency, effectiveness and consistency. The systems are easy to install, operate and maintain.
