Tank cleaning nozzles are typically stationary or rotating, and the type of nozzle you select will depend on the requirements for your application. Static nozzles work best where clogging is a problem because they have no moving parts. Rotating tank cleaning nozzles use mechanical force to provide better spray impact for effective soil removal. Also known as rotary spray heads, these devices require less time for cleaning and use fewer resources.
Types of Operating Principles
Stationary
Stationary nozzles, also known as static nozzles, have no moving parts. The low-maintenance designs of our innovative HydroClaw and spiral TW provide sizable free passage superior to standard static spray balls. The versatile size range and narrow form of the TW series ensure compatibility with small vessel openings.

Reactionary
These are fluid-driven tank cleaning nozzles use the reaction force of the spray media to drive the rotation of the nozzle head. These provide complete 360° coverage and efficient cleaning through impact and repetition. Rotating nozzles increase tank washing efficiency over static spray balls, saving time and money by reducing water and cleaning agent consumption, while decreasing downtime.
Rotary Spray Ball Nozzle
Rotary jets use the spray media flowing through internal gears on the body to rotate sets of high impact jet nozzles through an efficient 2-axis orbital pattern, providing complete 360° coverage. The jet pattern nozzles utilized on these assemblies provide significantly more impact and impingement force than other styles of tank cleaning nozzles, making them ideal for hard-to-clean residues and larger vessels.


Applying greater mechanical force to the cleaning process can reduce time, temperature, and chemicals, resulting in less water consumption and effluent discharge. The illustration below compares the mechanical force of a traditional static spray ball to a rotary tank cleaning device.
Spray balls are the main components for cleaning tanks and vessels, e.g. storage tanks, CIP tanks, milk collecting trucks. They offer a variety of sizes, flow rates and configurations for a broad scope of cleaning jobs. Spray balls as static cleaners are designed for flush cleaning with a high flow rate, thus providing powerful flushing at low pressure.
Advantages
- Low capital outlay
- No wearing parts
- Various possible spray patterns, materials and surfaces
- High flow rates
- Available for tank safety system VARITOP®
Applications
The Spray Balls ensure a professional and sustainable cleaning result in low pressure applications with a high cost efficiency and simple handling. They are ideally suited for low flow applications of soiling class 1 and are being used in numerous industries.
