Twin Motor Driver
Two pumps from one controller — duty shared, each motor protected on its own.
Runs a pair of pumps as one set: the lead pump alternates so both wear evenly, one or both run as demand needs, and each motor has its own full set of protections. Single or three phase.
| Supply | Single phase (1Φ) or three phase (3Φ) versions |
|---|---|
| Pumps | Two, from one controller |
| Working pumps | One at a time, or both together — you choose |
| Duty sharing | The lead pump alternates by start count, so both machines wear evenly |
| Protections | The full Motor Driver set on each pump separately — dry run, overload, under load, voltage, phase, over-cycle and over-run |
| Metering | Current on each pump · voltage on every phase |
| Applications | Level · pressure · temperature · dewatering |
| Connectivity | Wi-Fi to the Devyami app and web portal · over-the-air updates · RS485 Modbus RTU |
Why two pumps belong on one controller
Two pumps on two separate starters usually means one pump does all the work and the other sits idle until the day it is needed — and then turns out to have seized. The Twin Motor Driver treats the pair as one set. The lead role alternates, so both machines get run, and where the duty needs more than one pump both can run together.
Each motor keeps its own protection, so a fault on one pump is that pump’s fault — it is tripped, logged and reported while the set carries on.
For three or more pumps, see the Multi Pump Controller and multi-pump systems.
What it is used for
Each page shows the system working — the diagram, the logic and how it is installed.
Tank level automation
Fills the tank when it is low, stops when it is full — and never runs the pump on an empty sump.
See how it works →Remote control & alerts
Start, stop and see every pump from your phone — with the reason attached to every trip.
See how it works →Pressure boosting (HPN)
One steady pressure on every floor — held by a PID loop and a drive, not a pressure switch.
See how it works →Multi-pump sets
Two to six pumps share the work, stage in on demand and cover for each other on a fault.
See how it works →Motor protection
Dry run, overload, voltage, phase and over-cycling — caught before they burn a motor.
