Gearing for storm tank cleaning

The gearing for the StormBlaster™ is modified to produce a quicker but slightly less precise cleaning pattern than other rotary jet cleaners such as our Orbitors.  For hygienic applications the Orbitor will build up a very precise spray pattern over time.  The jets will effectively cover every square millimetre of the tank over time.  This is not strictly necessary for a non- hygienic application like stormwater attenuation tank cleaning.  A quick but robust wash cycle is required so that debris and residue can be removed for minimum water usage.

Sealed gear box
One of the most important design features is the presence of a sealed greased gear box within the machine. Process industry tank cleaners are normally lubricated by the cleaning fluid with an exposed gear system. This is sensible
in hygienic applications where contamination from lubricants is a considerable concern. In the oil tanker cleaning applications such contamination concerns are not present so a sealed lubricated gear box can be used. This then allows

far more particulate to be passed through the tank cleaner with little or no risk of clogging the cleaner.

In addition to its gearing, the StormBlaster™ is uniquely placed to clean large, dirty tanks due to:

Tough design
When designing rotary tank cleaners for use in process vessels the focus is on creating a hygienic and self-cleaning machine. It need to be polished and free from any nooks and crannies where contaminants or bacteria might hide. This

inevitably means some sacrifices need to be made in ruggedness. In contrast, stormtank cleaners have none of these concerns and so have been designed to be extraordinarily tough.

Large nozzles
The big tanker cleaners will have 14, 16 or even 20 mm nozzles. These can throw a cleaning jet over 25 meters. Bear in mind that means a cleaning radius of 25 meters meaning a 50 meter diameter tank could be cleaned with a single machine.
