Abstract

A precision pumping system is disclosed. The pumping system includes an electric motor assembly powering a first drive shaft driving a first pump at a first flow rate and powering a second drive shaft driving a second pump at a second flow rate. A proportioned fluid output includes a first fluid pumped by the first pump and a second fluid pumped by the second pump. The pumping system provides a desired ratio of the first fluid to the second fluid at the proportioned fluid output, relatively independently of pressure and flow rate at the output.
