        Self-Generating Pump

        Stress Engineering Services (SES) was asked to design and build a prototype chemical sprayer that would automatically and accurately mix chemical as needed at EXTREMELY high mix ratios (512:1), with great accuracy.

        Based on a list of design requirements, the SES development team designed and bench tested several concepts to identify the best approach.  The design calculations and bench testing were used for component selection/sizing, as well as early identification of the technical hurdles to be overcome.  SES based the initial prototypes on a commercially available platform that permitted most of the components to be hidden within the water tank.  The prototype passed client internal review and was approved for consumer placement testing.  SES assembled multiple units for consumer testing and additional marketing studies.
