ABSTRACT:
An improved surface treatment system, assembly, workstation and method for plating and the like. The assembly includes a suction pump along the treating liquid discharge end to circulate treatment fluid and avoid leakage. The assembly includes a member defining a fluid passage within the interior surface of a workpiece which is connected to a treating liquid feed channel and a treating liquid discharge channel. Advantageously, a washing fluid inlet is provided to permit a workpiece to be both treated and washed at the same workstation. The assembly may be used with a cover as an additional means to avoid leakage.
