ABSTRACT:
A self-purging auxiliary fluid supply system for supplying washout or makeup water or other fluids under pressure to a truck-mounted concrete mixing/dispensing drum is disclosed. The system includes a truck-mounted fluid reservoir for containing a quantity of fluid connected to supply fluid to an air-operated diaphragm pump connected to supply auxiliary fluid from the fluid reservoir under pressure to a discharge assembly. The pump further provides an integral purge system for displacing fluid in the fluid supply system after use.
