PW Intelligent Controller – 220V Twin Pump (Dual Operation)
The PW intelligent controller for 220V twin pump systems provides automatic control and full
electrical protection for two direct-start single-phase pumps.
Designed for twin-pump booster and transfer 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) 220V single-phase 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 (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
- 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 | 220V (single-phase) |
| Pump control | Twin pump (dual pump) |
| Pump power range | 0.37kW – 2.2kW* (per pump) |
| Dry-run protection | Adjustable time & current |
| Display | LCD (voltage, current, faults) |
*Actual maximum motor size depends on current rating. Always confirm motor full-load amps for each pump.
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 domestic booster sets, tank transfer systems, small irrigation with redundancy,
and light commercial water installations where continuity of supply is important.
