One platform, two modes

Steady-State & Dynamic — in one tool

Flowmax handles both normal hydraulic design and transient surge analysis within a single interface, so you never need to switch tools mid-project.

Mode 01

Steady-State

Hydraulic network analysis

Model pipes, pumps, valves, and tanks. Calculate pressure drops, flow distribution, and size your hydraulic system with confidence.

Mode 02

Dynamics

Transient & surge simulation

Simulate water hammer, pump trips, valve closures, and surge events. Evaluate surge protection and cavitation risk.

What Flowmax does

Build and solve hydraulic networks

Model complete liquid networks from simple pipe runs to complex multi-loop industrial systems.

Model pipes, pumps, valves, tanks, and pressure drops

Comprehensive component library covering all standard hydraulic elements used in process engineering.

Run different operating scenarios

Evaluate multiple operating conditions, flow rates, and configurations within a single model.

Export reports and calculation results

Generate structured engineering reports and export calculation data for documentation and review.

Designed for process, hydraulic, and oil & gas engineers

Built around the workflows and standards used by practicing engineers in industrial environments.

Visualise results

Clear pressure and flow profiles

Flowmax plots pressure and flow rate along any pipeline path, making it easy to identify bottlenecks, verify minimum pressures, and communicate results to clients.
