A complete, hands-on training system supporting basic introductory training in centrifugal pump operation. Imbedded subjects include; the demonstration of pump cavitation, the effect of the variation in static head and piping configuration on flow and pressure, as well as fundamental basic operational principles.

A modular piping system, coupled with a variable-height support structure, allows for convenient repositioning of the tank, pump, and motor creating new flow and static head conditions. Additionally, optional or user-supplied pipe spool variations can be added, creating many process flow conditions allowing for introductory training in the flow of liquid through fittings and pipe networks.

Useful in all courses relating to the flow of fluids through piping systems, as well as within introductory operations and maintenance courses related to centrifugal pumps and process systems, this device makes training in fluid flow and pump operating principles more memorable and effective.
