ReliaPump™ – the control brain for VFD-driven pumps

Uses the drive's own data (speed, current, torque) to know where the pump is on its curve, protects it from operating conditions that destroy seals and bearings, then optimises for energy savings. No extra flow meters or pressure sensors needed.

In simple terms: a good driver does not need a gauge to know the car is straining. ReliaPump is the same: it hears the pump "straining" through the VFD, adjusts speed automatically, stops the pump running dry or against a closed valve, and shares the work evenly across the station so fewer pumps need to run.

How it works

How ReliaPump works

1stepsReads VFD data2stepsDetermines the pump's operating point3stepsProtects & optimises speed4stepsCoordinates multiple pumps, reports
Dry-run protection – no false tripsDetects loss of liquid from VFD data and stops at the right time, without tripping on mere air bubbles.
Dead-head protectionA pump running against a closed discharge valve is the root cause of many seal failures – ReliaPump detects and handles it.
Run-out protectionPumps running too far right on their curve cavitate and vibrate – ReliaPump keeps them in the safe region.
Sensorless flow controlDigital Flow: flow-based control without a flow meter (hardware dependent).
Multi-pump flow balancingBalances flow rather than speed, compensates automatically for wear between old and new pumps, reduces the number of running pumps.
Makes use of VFD dataVFD data that is usually wasted goes to the cloud for reliability, energy and forecasting analytics.

How to start

If your plant has multi-pump stations, send us trends from the DCS or VFDs.

PlusSmart will tell you whether the pump group is at risk of unplanned failure, and whether the Sync or IQ module would help – before you invest in anything.

FAQ

ReliaPump frequently asked questions

Which VFD brands does it work with?

ReliaPump works with common industrial VFDs; some features (sensorless flow control, flow balancing) depend on the hardware – PlusSmart checks this during the assessment.

Do we have to replace our PLC or DCS?

No. ReliaPump integrates into your existing control system; the 24-pump geothermal project was upgraded without stopping the plant and without original documentation.

What are the main benefits?

No more seal failures from dead-head or dry running, no water hammer, fewer pumps running, energy savings and data for predictive maintenance.
