This invention relates to a self-contained, portable apparatus for admixing a plurality of liquids. The liquids, generally a diluent (such as water or an organic solvent), together with dilutable liquid chemical concentrates such as pesticides, fertilizers, and the like, are automatically proportioned and blended together to produce a resultant mixture, with controlled dispensing of the resultant mixture. The apparatus, which may be hand carried, is preferably powered by a battery source that is operatively connected to a positive-displacement pump. Such positive-displacement pump draws the liquids into the pump, utilizing the pump vacuum force, mixes the liquids in the pump chamber or housing, and thereafter discharges the resultant mixture from the apparatus, utilizing a suitable dispensing device.
