ABSTRACT:
The present invention discloses a liquid dispensing system and a method for dispensing liquid that includes two hermetically sealed tanks each having a liquid container with a conduit pipe connecting the two containers. A differential pressure exists between the two tanks such that a process liquid can be fed from the second container into a dispensing nozzle under the differential pressure and the gravity of the liquid without the need of a pumping system. The problems of gel formation normally observed in conventional dispensing systems can be eliminated. A high viscosity, short shelf life liquid can be most suitably dispensed by the present invention novel dispensing system and method.
