Abstract
A fluid-driven chemical product dispensing system dispenses fluid chemical product concentrates. The dispensing system includes a fluid drive unit powered by flow of a fluid, such as a diluent, and a pump which delivers the fluid chemical product concentrate from a supply to a destination. Upon exit from the fluid drive unit, the diluent is also delivered to the destination, where it mixes with the dispensed fluid chemical product concentrate to form a use solution. The dilution ratio of the volume of fluid chemical product concentrate dispensed per unit time versus the volume of diluent exiting the drive unit per unit time is constant over a defined range of diluent flow rates.
