2 Tank cleaning nozzles General design families Shared characteristics: Lowpressure application. Your benefit: lower energy consumption coupled with less wear and tear. Rotational cleaners: driven and lubricated by the cleaning liquid. Your benefit: no need for elaborate drive mechanisms. A B C Freespinning heads The cleaning liquid turns the spray head by means of specially positioned nozzles. Rapidrepetition impact loosens the dirt and washes it off of the tank surfaces. The effect is best at low pressures in small to mediumsize tanks. Series , , , 566/569/573/583 Typical gravity drainage flow 1" 22,71 l/min 1 1/2",20 l/min 2" 87,10 l/min 2 1/2" 132,48 l/min 3" 189,25 l/min F D Internal regulated drive The liquid flow powers the head by way of an internal turbine. This keeps the speed of the head within its optimal range across a wider span of pressures, and the nozzle develops more powerful spray propagation and a wider range. Series 5/519 Static spray balls Static spray balls do not rotate, so they require a comparatively large amount of liquid in order to generate turbulent flow. They are used primarily for washing down relatively small tanks and vessels. Series 540/591 For more information please ask for our special brochure Tank Cleaning Nozzles Typical applications A Position the tank cleaning nozzle(s) at the center of the tank, roughly onequarter of the distance from top to bottom. B Nozzles invariably leave an unsprayed shadow area directly overhead, the size of which varies according to the type of nozzle and the piping. C The distance between the top of the tank and the nozzle should amount to approximately onequarter of the nozzle's action radius. Size your unit to ensure sufficient flow to the top part of the tank wall. D The film of liquid grows thicker toward the bottom of the tank, where the washing effect is the most pronounced. Standing water reduces impact and allows solids to accumulate. Make sure that the drain can handle whatever you put into the tank. F The longest spray distance is from the nozzle to the bottom corner, so the nozzle should be sized for this "effective washing distance". All pressure data are stated in terms of differential pressure directly at the nozzle, so be sure to take the linepressure drop into account. 7.2
