Pump Automation
Single-phase to three-phase. Borewell, submersible, jet, and booster pumps. Dry-run protection, phase failure protection, level-sensor integration. 0.5 HP to 50 HP.
The most common reason a motor burns in India is not a winding defect. It is a protection gap. Subtech pump automation panels close all three gaps automatically.
What Does a Pump Automation Panel Do?
A pump automation panel does three things a manual starter cannot: it starts the pump automatically when water is needed, stops it automatically when the tank is full or the borewell is dry, and shuts the motor down before damage occurs if a protection condition is detected.
For a borewell pump, the panel monitors the water level in the borewell via a float switch or electrode probe.
For overhead tank filling, the panel monitors the tank level via electrodes or a float switch and stops the pump when full.
Municipal and institutional installations typically run two or more pumps. The automation panel handles auto-changeover between pumps, equal run-hour rotation, and start/stop sequencing.
Why this matters for your facility
Dry-Run Protection. The Motor Stops Before It Burns.
Borewell and submersible pump motors fail when they run against air. The panel detects zero-flow or low borewell level and stops the motor within seconds.
Phase Failure and Phase Imbalance Protection.
A three-phase pump motor running on two phases draws 40-50% more current on the remaining phases and fails within minutes.
Auto Start / Stop on Tank Level.
Electrode probes or float switches in the overhead and sump tanks tell the panel exactly when to start and stop.
Auto-Changeover Between Duty and Standby Pumps.
For jockey-plus-main pump pairs, the panel automatically rotates duty to equalise run hours.
GSM / SMS Remote Control (Optional).
An optional GSM module lets you start or stop the pump by SMS or via a mobile app.
Over-current, Under-voltage, and Over-voltage Protection.
The panel monitors supply voltage continuously.
Where Subtech panels are deployed
Borewell Pumps for Agriculture
Submersible borewell pumps on agricultural land run unattended for hours.
Residential and Commercial Booster Stations
Apartment complexes and commercial buildings rely on booster pump panels to maintain water pressure.
Municipal Water Supply: UP Jal Nigam, Delhi Jal Board
Gram panchayat and municipal pumping schemes use Subtech pump automation panels with GSM telemetry.
Hotels, Hospitals, and Institutions
Domestic water supply for a 100-room hotel or a 300-bed hospital cannot depend on a manual operator.
Industrial Process Water and Cooling Towers
Process water supply for manufacturing plants and cooling tower circulation pumps need continuous operation.
