Mixing apparatus is described in which a plurality of chemical materials are to be incorporated in a carrier liquid, which may be a solvent, such as water, and which is quantitatively predominant, some of the chemical materials being incompatible if brought together directly, or in a wrong sequence, or which are difficult to combine, the materials being combined in the desired proportions in a series arrangement of liquid filled rotary motor driven pumps, the respective materials in the desired proportions preferably being supplied from separate sources of materials by reciprocating pumps, the delivery of the carrier liquid being to a first rotary motor driven pump to which a first chemical material is supplied, the first rotary motor driven pump having a fluid connection between its intake and delivery portions for repeated circulation and agitation of the liquid for mixing, with a tap for fluid input of the carrier liquid and first chemical material and a tap for fluid delivery connected to a fluid connection. Additional rotary motor driven pumps are provided for repeated circulation and agitation of the liquid for mixing and each with fluid input taps and delivery connections. The pumps are preferably simultaneously driven from a single power source with shut-off upon exhaustion of one of the materials and with continued operation of the rotary pumps after the reciprocating pumps have been shut-off.
