ABSTRACT:
An integrated system and method are disclosed for filtering a fluid and for dispensing a desired volume of the fluid. The integrated system includes a feed pump sub-assembly for receiving fluid and for directing the fluid through a filter. A filtration sub-assembly is joined with the feed pump sub-assembly for receiving fluid from the feed pump sub-assembly and for housing the filter. A dispense pump sub-assembly is integrally joined with the filtration sub-assembly and defines a dispense chamber for receiving filtered fluid from the filtration sub-assembly. The dispense pump sub-assembly includes a dispensing means which is moveable from a fill position to a purge position for purging at least a portion of any gas bubbles from the dispense chamber. The gas bubbles are purged through a purge outlet disposed above a fluid inlet and a fluid outlet of the dispense chamber. The dispensing means is also moveable from the purge position to a dispense position for dispensing a desired volume of the fluid from the integrated system.
