A fluid mixing apparatus (10) for combining into a uniform mixture at least two liquid components includes a reciprocating left positive displacement pump (18) and a reciprocating right positive displacement pump (20) isolated from the left pump (18). The left pump includes a first metering cylinder (22) associated with a first liquid component and a second metering cylinder (24) associated with a second liquid component. The right pump (20) includes a first metering cylinder (26) associated with the first liquid component and a second metering cylinder (28) associated with the second liquid component. While the left pump (18) is measuring a predetermined volume of the first and second liquid components, the right pump (20) is pumping a predetermined volume of the first and second liquid components to a receptacle (14), and vice versa for when the right pump (20) is measuring in order to provide a continuous flow of the first and second liquid components to the receptacle (14).
