- Version 3 - Piping System Design Software


HYDROFLO 3 is a powerful, yet easy to use Pump and Piping System Analysis software tool. Any type of incompressible liquid flow can be analyzed. Many types of conveyance systems can be modeled including open source/discharge, closed re-circulating and gravity flow systems. Industrial process, water supply, wastewater treatment, fire protection, sprinkler systems, chemical process, mine de-watering, swimming pool, pond/irrigation and HVAC systems can be quickly created, analyzed and solved for steady-state flows and pressures and operating parameters. Models can contain up to 10 sources and discharges with 9 branches and 1000 elements. Virtually any type of piping system element can be described using the wide variety of hydraulic modeling components available. Custom element head losses can be described using flow vs. head loss curves, fixed head losses (at any flow) or by specifying custom friction coefficient values.

HYDROFLO 3 is fully International and Unicode compliant, offers all standard English and metric/SI units and is localization tested. Academic versions of HYDROFLO, PumpBase and HCALC have been included in 3 editions of collegiate level textbooks.

Systems are built in a unique vertical workspace that offers easily viewable suction and high-head conditions along with Hydraulic Grade Line elevations and pressures. The Hazen-Williams and Chezy-Manning equations are available for use with water systems and the Darcy-Weisbach equation is available for use with any type of incompressible fluid of known viscosity (a full database of liquid properties is available for selection).

New HYDROFLO to PumpBase Data Transfer - Once HYDROFLO determines your system's Total Dynamic Head and Operating Flow, one click brings up  PumpBase™ to find the best pump for your application. The selected pump's curve can then be sent back to HYDROFLO for use in your design. The two programs work together seamlessly, finding and launching each other if they are not currently running.

Fluid conveyance system models can be built quickly and easily by dropping elements (pipes, pumps, tanks, gauges, fittings and valves) onto the workspace in sequence using the many editing features included with HYDROFLO (see our video tutorials). Both a Clipboard and Group Editor are available for the mass editing, storage, moving and copying of elements. The Clipboard facilitates moving large groups of elements between lines and separate projects. Clipboard files can be saved with or separately from project data files, so that large groups of elements can be easily imported into other designs. The Group Editor allows the detailed location and selection of elements based on specified criteria and applies mass editing actions to those elements. Fly-over element inspection (hovering over elements) lets you rapidly identify system properties and results. Elements can be increased in size for easier viewing. Many example problems are available and can be loaded and used as templates for your own system designs.

The extensive help file describes hydraulic theory, efficient program use and practical application techniques. Solution statistics are presented to help determine design stability and accuracy. Suggestions are presented to guide the user in correcting model errors. Once a system is built, PDF reports of head losses, flows, pressures, line and pump graphics and other operational results can be previewed and printed.

A full selection of Pipe Schedules is available for use and the available Pipe Schedule Editor allows users to add, edit, export and import their own schedules.
