ABSTRACT:
An assembly for cleaning a tube bundle includes a plurality of elongate tubular lances movable within an outer shell. A flexible fluid hose within the shell extends from an input port in the upper portion of the assembly to the manifold in the lower portion of the assembly, which in turn transmits pressurized fluid to the plurality of lances. The hydraulic motor powers a rack and pinion assembly to reciprocate the lances, while a plurality of spring biased plates each cover a slot in the lance housing. The assembly of the present invention utilizes a receiving manifold and a lance manifold connected by a plurality of nipples for a desirable low pressure drop. A pair of series connected valves allows the hydraulic fluid flow and the pressure to the drive motor to be separated controlled.
