Pump Health Monitoring & Control
Autonomous dry-run protection, Motor Current Signature Analysis (MCSA), and cloud switching to eliminate catastrophic pump burnout.
Introduction
Catch pump trouble before the motor burns out.
Pumps are the workhorses of water infrastructure, yet dry running, voltage surges, phase failure, and bearing wear cause frequent breakdowns and expensive rewinding. Bulfro Aqua ESG’s Pump Health Monitoring & Control (PHMC) platform continuously evaluates electrical waveforms and thermal signatures, stopping faults instantly and putting full on/off control in the palm of your hand.
Predictive Intelligence
Active Motor Current Signature Analysis
Traditional thermal overloads only trip after the motor windings have already heated up to damaging levels. PHMC uses high-speed digital sampling to track voltage and current harmonics in real time.
When an intake pipe loses suction or a foot-valve gets clogged, the system instantly identifies the current drop, cuts the contactor within milliseconds, and flags an immediate dry-run alarm to your operators.
Core Capabilities
Total Pump Safeguarding & Control
Designed for industrial plants, lift irrigation schemes, and municipal water pumping stations.
Instant Dry-Run Tripping
Monitors active power factor and current drop under no-load condition, tripping the motor in seconds to save the impeller.
Millisecond DetectionFull Phase Protection
Prevents motor burnout caused by phase loss, single phasing, unbalance (>5%), or wrong phase sequence during grid switching.
3-Phase Voltage & CurrentMobile App & SMS Switching
Command pumps remotely via cloud web dashboard, Android/iOS app, or standard SMS commands with automated status feedback.
Remote On / Off ControlEnergy & Efficiency Audit
Continuous logging of kWh, running hours, and power factor to pinpoint degrading pump performance before catastrophic failure.
Class 1.0 Energy MeteringAutomated Tank Interlock
Integrate seamlessly with Bulfro Aqua ESG tank level sensors (BTLMS) to start pumping when tanks are low and auto-stop on full capacity.

Frequently Asked Questions
Frequently Asked Questions
Find direct answers to common questions regarding PHMC motor protection, dry-run detection, switching, and starter wiring.
When a pump loses water suction, the mechanical resistance on the impeller drops sharply, causing an immediate change in active current and power factor (cos φ). PHMC analyzes these electrical signatures through Motor Current Signature Analysis (MCSA) at the surface starter, cutting the motor off without requiring downhole water probes.
Yes. The PHMC unit connects via 4G/GSM to the Bulfro Aqua ESG mobile application and cloud dashboard. Authorized operators can switch the pump on or off from anywhere, set daily automation schedules, or even send simple SMS commands if cellular internet is weak.
Yes. PHMC connects directly into the control wiring of existing DOL, Star-Delta, Soft-Starter, or VFD panels. Its potential-free relay contacts control the starter's contactor coil without requiring replacement of your existing switchgear.
If any phase drops or voltage unbalance exceeds preset limits (typically 5%), PHMC trips the pump within milliseconds to prevent extreme winding overheating. Once healthy voltage returns and stabilizes for a configurable delay, the unit can auto-restart the pump safely.
Yes. PHMC includes Class 1.0 energy calculation measuring voltage, current, active power (kW), total energy (kWh), and running hours. This lets you calculate specific energy consumption (kWh per cubic meter) when paired with a flow meter.
The internal lithium battery backup immediately detects grid collapse and triggers an emergency SMS and cloud alert to the maintenance team, confirming whether the stoppage was caused by a grid outage rather than an internal mechanical fault.
