HYDROFLO Workspace

Piping System Design Software
for Windows 

Download the Full Version of HYDROFLO 3 and use it FREE for 15 days!

The new features in HYDROFLO 3 allow you to do more work faster! Quickly create and solve networks, recirculating and gravity flow piping systems for their steady-state flows and pressures. The intuitive drag-and-drop interface with many new editing tools and analysis features make your valuable design and analysis time more efficient and productive. The unique vertical Hydraulic Grade Line workspace allows you to see piping system lines with their representative elevations, pressures and HGLs. Hover over an element to see it's parameters and operating results.

Our software is extensively tested for International use, making full use of Unicode and your localization settings under all Windows OS versions.

The Pipe Schedule Editor offers full creation and editing of any type of pipe material and size. Supply elements can now end branch lines allowing more sources and discharges within systems.

Communication between HYDROFLO and PumpBase is now bi-directional. HYDROFLO will determine a pump's operational parameters and send it to PumpBase for best pump selection. PumpBase then sends back the selected pump curves to HYDROFLO!

Advanced Pump Selection and Catalog Production

Just A Few Of The New PumpBase Features
Curve Entry via Image...

Graphical Curve Entry - PumpBase 3 introduces the ability to enter pump curves directly from images. Load jpg, bmp or gif images then click on the points of the curves to obtain head and flow values - eliminates guessing and estimating! (see image right) Curves are then plotted on top of the image for confirmation.

Multi-Stage Analysis - Detailed calculation of the exact trim sizes required for balanced multi-stage operation and their sequence order - this will save you a lot of time!

Catalog Building - Pump Manufacturers can now build complete Catalogs of their pump lines and combine them into a single file for distribution using the Catalog Builder version. PumpBase does version tracking so the latest information is always installed on a user's system and out-dated information is removed.

Catalog Builder - This version does it all from Pump Selection to Pump Catalog Production.

User - View and select Pumps and load any Pump Catalog.

Academic - This version is limited in Pump and Catalog capacity, but performs all the same pump selection, pump editing and calculations. It does not load additional Pump Catalogs and can only be used for research purposes.

New Academic versions of PumpBase 3, HYDROFLO 3 and HCALC are available!

Ever since our products have been included with 3 editions of Robert Mott's College level textbook "Applied Fluid Mechanics", published by Prentice-Hall, (Thank you, Bob!) we have had an excellent academic following. We continue those efforts by providing a new download page that provides software that is "free-to-use" for non-commercial use. We hope that up-and-coming engineers find the software useful in learning the methods and concepts of fluid system design theory and analysis. Educators and students can install the software on an unlimited number of teaching PCs. This is an economical way to expose students to the latest design technology for modeling piping systems.
