⚙️ Key Features & Engineered Advantages
Dual Motor Sump & Borewell Operation
Designed to control one sump motor and one borewell motor pumping to a single common overhead tank.
Intelligent Mode Switchover
Operates on Sump Mode when water is available; when sump water drops below the foot valve level, it automatically switches over to Borewell Mode, resuming Sump Mode once the sump refills.
3-Position Pump Selector Switch
Features a physical selector switch for Auto, Pump 1, or Pump 2 operation. In Auto, both run automatically; selecting an individual pump isolates the other.
Advanced AC Sensing Technology
Software-driven AC sensing eliminates electrode polarization in water, paired with stainless steel molded conductive electrodes lasting up to 10 years.
Dry-Run & Voltage Protection
Includes dry-run detection with a 120-second delay, automatic voltage cut-off below 170V or above 270V AC (single phase / 360V-480V 3-phase), and built-in surge protection.
Manual, NEED & Bypass Switches
Includes Auto/Manual soft switch for utility tasks, an optional NEED switch to force-start irrespective of tank levels, and a Rocker Bypass Switch for failure overrides.
