ABSTRACT:
A water pressure intensifying system for providing elevated water main pressure from water at a relatively low pressure head, such as may be available from a slowly flowing stream, for example. The basic system comprises two in-line cylinders of different diameters with the pistons being coupled together by a connecting rod. Associated valving directs water flow so that the low pressure water driving the large piston causes the small piston to produce water flow at substantially increased pressure. Multiple pumps can be driven in parallel in a companion pump battery from control valving associated with a single pump in a basic system, thus substantially reducing the cost of adding flow capacity to a basic pumping system of the invention. A modification of the system can be used as a proportional flow mixing system such as, for example, adding chlorine to a water supply in a municipal treatment plant.
