Real-time pump-curve and system-curve interaction
Adjustable pump speed and valve position with a live operating point.
PiPump is real-time centrifugal pump and pump-around loop simulator software that models pump-curve behavior, flow-pressure interaction, and NPSH/cavitation risk, without putting a real pump at risk. Built by PiControl Solutions, PiPump is process control simulation software for engineer training, pump-system troubleshooting practice, and fluid-mechanics education. It runs the operating point where the pump curve and system curve intersect in real time, so engineers can watch how valve position, pump speed, and suction conditions move that point, and how close it gets to a cavitation limit.
Cavitation and dead-heading are two of the most common causes of unplanned rotating-equipment damage in a plant, and both are easy to trigger by accident on a real pump-around loop. PiPump reduces that risk by letting engineers practice low-flow operation, suction-lift changes, and pump-speed adjustments on a digital twin first, so the first time they push a real pump toward its limits is not the first time they see what happens.
PiPump simulates the real-time dynamics of a centrifugal pump-around loop (pump curve, system curve, suction and discharge pressure, and flow) so engineers can build intuition for pump-system behavior and cavitation risk under realistic conditions. PiPump runs on standard Windows hardware, requires no rotating equipment, and models the same interaction between flow and pressure that engineers later manage in advanced process control of pump and compressor networks.

Industrial plants use PiPump to train new process engineers and operators on pump-around loop behavior, cavitation avoidance, and pump-speed and control-valve coordination before they touch live rotating equipment. Because building and testing physical pump loops is costly and time-consuming, PiPump's digital-twin approach gives plants a repeatable way to build that judgment for equipment used across industrial process control systems.
Engineering colleges and universities use PiPump to teach pump-curve fundamentals, system-curve interaction, NPSH and cavitation theory, and process control concepts in fluid mechanics and unit operations courses. PiPump replaces static pump-curve handouts with hands-on simulator practice on a fully interactive digital twin.
PiPump's feature set is built for one outcome: engineers who understand pump-system behavior, and its limits, before they operate a real pump-around loop.

Cavitation and dead-heading are among the most common causes of unplanned rotating-equipment damage in a plant, and both are the kind of mistake an engineer usually only makes once. The traditional ways of learning pump-system behavior (a handbook pump curve, a classroom lecture on NPSH, and on-the-job practice on a live pump-around loop) share one structural limitation: none of them shows the learner how the operating point actually moves in real time as speed, valve position, and suction conditions change together.
A handbook pump curve shows head versus flow for one fixed speed and one fixed system resistance. It never shows how the operating point slides when a valve is throttled, a pump is slowed down, or suction pressure drops. Engineers who can read the chart are often unprepared when the real loop behaves differently.
NPSH and cavitation theory transfer terminology but not judgment. An engineer who can recite the NPSH margin formula can still dead-head a pump or run it too far into low flow, because recognizing cavitation risk comes from watching a margin shrink in real time, not from a lecture slide.
OJT on a live pump-around loop is how most engineers actually learn, and it carries real cost: impeller damage, seal failure, and unplanned downtime, accepted as the price of learning. Plants would prefer that learning curve to happen somewhere else.
PiPump removes the structural problem: a live pump curve and system curve, a live NPSH margin, and a digital-twin loop that reacts the way a real pump-around loop reacts, with no rotating equipment at risk.
PiPump focuses on pump-curve and NPSH behavior. For the other loops that surround a pump-around system, PiControl builds standalone simulators for each control variable.
PiFlow simulates a flow controller in a heat-exchanger loop, capturing flow-loop dynamics with realistic valve characteristics and pump curves, a natural companion to PiPump's pump-around loop focus.
PiDeltaP simulates pressure-drop dynamics across piping, control valves, and process equipment, the discharge-side counterpart to the suction-and-cavitation behavior PiPump models.
PiLevel simulates a level controller in a vertical tank, modeling integrating-process behavior and cascade level-flow control, which routinely feeds the pump-around loops PiPump trains engineers on.
Engineers train on PiPump across every sector PiControl serves — each runs pump-around loops with different dynamics, and PiPump's configurable pump and piping data reproduce the loops their own plant runs.
PiPump is used by process engineers and instructors across water management, refining, petrochemical, and chemical-manufacturing operations, and by university fluid-mechanics and process-control programs, as part of PiControl's simulator family for engineer training and operator preparation.
