SmartLift Duplex
Runs on SmartController
Controls two pumps that empty a wet well. The lead pump starts when the well rises to the start level and the lag pump joins it if the level keeps climbing; both stop once the well is drawn down. Pumps can rotate the lead role every cycle so they wear evenly. Well level can come from a radar, an analog rod sensor, or four floats, and the station keeps running on a backup source if the primary sensor fails.
