The year was 1980 in Indiana, Pennsylvania where Engineered Software, Inc. co-founder, Carolyn Popp took courses in Microcomputer programming while her partner, Ray Hardee worked at a coal power plant, where he used a programmable calculator. Due to the extensive data entry, they realized there had to be a more efficient way to calculate the flow of fluids. Carolyn soon began writing the award winning software known today as PIPE-FLO® on a wooden door held up by a kitchen stool and TV box. 

Fast forward to 1982 – the year when TIME Magazine’s “Man of the Year” was a computer - ESI was born. Soon afterwards, PUMP-FLO™ and NET-FLO were developed and the software was packaged as the FLO-SERIES. A majority of the first copies of the software were sold in Portland, Oregon at the Pressure Vessel and Piping Show.

With nearly a decade under their belt, ESI hired their first employee, began interfacing with AutoCAD and jumped on board with Windows version 1. (Yes, version 1.) After a few successful direct mail marketing campaigns, ESI was able to land Goulds Pumps – one of the largest pump manufacturers in the world.

It’s now mid 1990’s and ESI’s employee count has reached double digits and their sales department was born. This allowed Ray and Carolyn to attend events such as the National Software Retail Association where they met Bill Gates and talked personally about the future of Windows. Soon afterwards, PUMP-FLO hit the ‘world wide web’ – known today as the internet.

In ESI’s 33 years of existence, it has grown into a global software provider for over 3,000 clients worldwide. With partners such as Weyerhaeuser, Shell Oil and Chevron, ESI continues to grow through their unsurpassed software development and ethical business practices.

Our Products

Engineered Software, Inc.’s hydraulic analysis program, PIPE-FLO®, is widely used for Engineering, Commissioning, and Operations of gas and liquid piping systems around the world to help companies design, optimize, and reduce capital and operating costs of their fluid piping systems.

Originally conceived in 1986, PUMP-FLO™ was the world’s first centrifugal pump selection program. Today, the PUMP-FLO™ suite of products is used by pump manufacturers, distributors, and buyers to streamline their pump sizing, configuration, selection, quotation, and pricing processes.

The most recent addition to ESI’s growing portfolio of products is ESI Learning. Launched in 2008, ESI Learning offers several training courses on industry related topics ranging from Centrifugal Pumps to Piping System Assessment and Optimization that bring valuable information to industry professionals.

Our Vision and Mission

Engineered Software, Inc. envisions a world where fluid piping systems are intelligently designed to leave a smaller environmental footprint while improving the reliability and ROI of industry's hidden infrastructure.

ESI’s Mission is to assist our customers in realizing energy efficiencies through improved piping system understanding and superior equipment selection. We do this in three ways:

1. Develop flexible software which simulates, troubleshoots, and communicates the optimal operation of liquid and gas systems over the lifetime of a facility.
2. Create intuitive software for efficient pump and equipment selection and configuration.
3. Advance industry knowledge and propagate best practices in the design and operation of plant systems through strategic partnerships, industry advocacy and educational programs.
