Abstract

The invention relates to a high pressure cleaning device comprising a motor driving an internally toothed gearwheel pump for supply of a cleaning fluid, under high pressure, to an outlet device. Said internal tooth gear and/or an external tooth gear comprise a molybdenum containing chrome steel alloy which also contains a nitrogen component of 0.1 - 1 % and which increases the corrosion resistance and hardness of the toothed gearwheels.
