Abstract
A fluid driven tank cleaning apparatus which uses part of the cleaning fluid supplied to the device for lubricating the gear train located in a separate compartment. Passageways are positioned and sized so as to maintain the separate compartment substantially filled with the cleaning solution at a relatively low pressure and flow rate therethrough. The device is constructed to minimize the corrosive effects of cleaning fluid on the moving parts.
