Shanghai 3S Global Company Limited
3S-32-PA High-Compatibility Duplex Pump Smart Control Panel
It supports multi-power output and 8 control logics, with built-in automatic duty/standby switching. The 3 Phase Booster pump controller is compatible with booster pump sets, water supply pump sets, and fire pump sets, helping pump manufacturers efficiently achieve complete machine matching.
1. Signal Input Compatibility: Adapts to different pump sets and project needs, easily connecting to various control signals.
Booster pump sets (pressure maintenance): 0-5V remote pressure gauges, electric contact pressure gauges, 4-20mA pressure transmitters, flow switches, pressure switches, etc.
Water supply pump sets (liquid level control + dry running prevention): Float switches, 4-20mA liquid level sensors, electrode-type liquid level probes, etc.
Fire pump sets (emergency start + ultra-high reliability): Pressure switches, flow switches, 4-20mA pressure transmitters.
2. Power Supply Compatibility: Whether for countries with low, standard, or high voltage, one unit works universally, effectively reducing inventory pressure of different controller types.
This 3 Phase Booster pump controller supports single-phase AC110-250V and three-phase AC220–415V (AC440-490V optional), and can automatically adapt to 50Hz/60Hz power grids.
3. Start-up Mode and Power Compatibility: Easily adapts to 0.37–500 kW pump sets
The Duplex Pump Smart Control Panel can freely combine DOL, star-delta, auto-transformer reduced voltage starting, and soft start modes.
4. Extended Function Compatibility: Easily meets personalized project needs, leading the new era of intelligent IoT.
The signal board reserves multiple sets of terminals for easy expansion of additional signal devices.
The 3 Phase Booster pump controller can be expanded with remote control, including RS485 (Modbus RTU), IoT, and WiFi, enabling seamless integration into PLC, BMS, SCADA, DCS, and HMI systems.
8 dual-pump control logics adapt to entry-level to high-end control needs
Logic feature: One pump operates, the other stops.
Value for pump manufacturers: Used in small systems or entry-level models, this Duplex Pump Smart Control Panel helps manufacturers provide low-cost solutions to meet basic water supply needs.
Simultaneous Dual-Pump Start
Logic feature: Both pumps run simultaneously to instantly enhance water supply capacity.
Value for pump manufacturers: This 3 Phase Booster pump control is ideal for matching fire pumps or emergency booster pump sets, making manufacturers’ products easier to pass safety standard certifications.
Duty/Standby – Pump A Duty, Pump B Standby
Logic feature: Pump A runs long-term, while Pump B stands by.
Value for pump manufacturers: Ensures water supply continuity, reduces user complaints and after-sales risks, and improves the overall reliability of pump sets.
Duty/Standby – Pump B Duty, Pump A Standby
Logic feature: Pump B runs, while Pump A stands by.
Value for pump manufacturers: the Duplex Pump Smart Control Panel flexibly adapts to different owners’ needs, reducing modification costs for manufacturers across various projects.
Alternating Duty
Logic feature: The two pumps automatically switch based on operation time or frequency.
Value for pump manufacturers: Extends the lifespan of pump bodies and motors, reduces customers’ long-term maintenance costs, and enhances manufacturers’ competitiveness in bidding or promotion.
Timed Rotation Under Alternation Duty
Logic feature: Forces pump switching at fixed intervals even without task changes.
Value for pump manufacturers: Prevents pump damage caused by long-term continuous operation of a single pump, ensures balanced operation time of the two pumps, and improves manufacturers’ reputation.
Parallel Alternation with Load Sharing
Logic feature: Depending on system needs, the pump set can operate alternately or in parallel, intelligently distributing loads.
Value for pump manufacturers: This 3 Phase Booster pump control supports high-end projects such as smart buildings and industrial systems, helping manufacturers enter higher-end market segments.
Pure Timer Control
Logic feature: No need to connect any sensors; controls the start/stop of the two pumps solely through time logic.
Value for pump manufacturers: Suitable for low-cost scenarios or simple pump sets, helping manufacturers expand price-sensitive markets.
From entry-level to high-end projects, the 3S-32-PA Duplex Pump Smart Control Panel provides pump manufacturers with an all-in-one dual-pump control solution, reducing design modifications and lowering development difficulty.
