Industry Overview


As a full-service engineering firm, Parker, Messana & Associates work on large, complex systems with multiple branches and pumps. Many of their projects are rebuilds and retrofits where they are adding to existing systems where problems are already occurring. In order to conduct hydraulic analysis the company used a spreadsheet designed in-house by one of their engineers. However, because the spreadsheet was limited to analysis of one pump, in complex systems multiple spreadsheets were needed to conduct the analysis. This was both cumbersome and time-consuming. Parker, Messana & Associates needed a hydraulic analysis tool that was both efficient and easy-to-use.


Searching for a hydraulic analysis tool that could effectively troubleshoot existing systems as well as design new systems, Parker, Messana & Associates turned to PIPE-FLO®.

“PIPE-FLO® is a very powerful tool when we are examining an existing system that has a problem but we don’t know what it is. We simply plug in the whole system, determine the problem, and run scenarios to fix the problem. This allows us to troubleshoot the system at a minimal cost,” Parker said.

Another outstanding feature of PIPE-FLO® is the ability to select pumps from over 70 pump manufacturers directly from the program.

“Being able to do our pump sizing in PIPE-FLO® by looking at the digitized pump catalogs is a major timesaver. It is great to be able to consider variable speed drive pumps and look at the pump curves to see how they will run in the system. PIPE-FLO® pump selection allows us to do a better job of selecting the right pump for the right situation,” Parker said.

Parker, Messana & Associates work with clients who also use PIPE-FLO®, creating the opportunity for a lifetime design document and collaborative engineering.

“We have clients who have the PIPE-FLO® program so we are able to hand them the design to use after construction is complete. We have even had situations where we have handed the system off to our clients during the design phase and traded it back and forth. It creates a dynamic design tool,” Parker said.

Overall, the company is pleased to have a hydraulic analysis tool that makes their job easier.

“PIPE-FLO® is a joy to operate from an ease-of-use standpoint. It is much quicker and much easier than using a spreadsheet. Many decades ago, when I was first getting into hydraulic analysis, I was hopeful that somebody could create the ideal program to meet the needs of engineers. I have found the ideal program in PIPE-FLO®,” Parker added.
