Abstract
A foam liquid proportioner including a positive displacement water motor coupled to a positive displacement foam liquid pump is provided with a gear drive mechanism which steps up the RPM of the foam liquid pump to be much higher than the RPM of the water motor to a speed so as to reduce the ratio of the slippage of foam liquid to the total flow of the foam liquid through the foam liquid pump.
