PW Intelligent Controller – 380V Twin Pump (Dual Operation)
Multifunction intelligent controller for automatic control and full electrical protection of
two direct-start three-phase pumps (0.75kW to 15kW). Designed for twin-pump booster,
borehole and irrigation systems using duty/standby or alternating operation.
What this controller is designed for
This PW Intelligent Controller is designed to control and protect a
twin-pump (dual pump) three-phase 380V system.
It is typically used where reliability is important—one pump runs as the primary pump
and the second pump serves as standby, or the controller alternates between pumps to balance run-time.
Twin pump control is normally used for duty/standby or alternating operation.
If you require both pumps to run together at the same time (true parallel boosting),
confirm this requirement before ordering so we supply the correct setup.
How twin (dual) pump operation works
- Duty/Standby: Pump 1 runs normally; Pump 2 takes over if Pump 1 faults or cannot meet demand.
- Alternating: The controller alternates between Pump 1 and Pump 2 to equalise wear and run hours.
- Fault handling: In the event of a fault (phase loss, over-current, dry-run, etc.), the controller alarms and can switch to the standby pump (if configured).
Key features & protection functions
- Automatic or manual control of two pumps
- Duty/standby and alternating operation (system dependent)
- Dry-run protection with adjustable time and current settings
- Over-current protection
- Over-voltage and under-voltage protection
- Short-circuit protection
- Phase loss protection (3-phase)
- Built-in isolator / air switch
- High-definition LCD display
- Visual and audible fault alarms
Supported control modes
The controller supports multiple working modes and can be connected to:
- Pressure sensors
- Float switches
- Level probes
- Mechanical pressure switches
- Electrical contact pressure gauges
Technical specifications
| Parameter | Value |
|---|---|
| Supply voltage | 380V (three-phase) |
| Pump control | Twin pump (dual pump) |
| Pump power range | 0.75kW – 15kW (per pump) |
| Dry-run protection | Adjustable time & current |
| Display | LCD (voltage, current, faults) |
Important: For twin systems, confirm the full load current (amps) for each pump and the desired operating logic
(duty/standby, alternating, or both pumps together if required).
Typical applications
Twin booster pump sets, commercial water supply systems, irrigation setups requiring redundancy,
borehole applications with backup pump capability and any installation where continuous water supply is critical.
