How It Works

Working diagram

The BMNP system uses a purely mechanical float to control the pump. As the tank fills, the float rises and mechanically trips a switch to cut power to the motor when the full level is reached. When the water level falls, the float drops back and the switch closes, allowing the motor to run again. This gravity-based mechanism requires no sensors, no electronics, and no extra power to detect levels.
