- Unmanned Pump Control, Choose 3S
Shanghai 3S Global Company Limited
Chemical plant backup pump systems, hospital dual water supply. This3 phase dual pump intelligent control box ensures 24/7 uninterrupted operation via dual pump duty/standby + Modbus protocol, seamlessly integrating with central control platforms.
◎Seamless Dual Pump Rotation, Ensures Continuous Water Supply
Utilizes advanced no-break switching technology for intelligent alternation between Pump A and B, eliminating water interruption risks during switching and guaranteeing stable system water supply.
◎Flexible Multi-Mode Control, Meets Diverse Needs
The3 phase dual pump intelligent control box supports alternation, duty/standby, and single pump independent control, with configurable rotation time for precise management and balanced pump lifespan.
1. Single Pump:
Used when one pump is under maintenance; the system keeps the other pump running continuously.
2. Dual Pump Simultaneous Start:
For applications with high flow demand or emergency use, where both pumps start together.
Pump A Duty / Pump B Standby (and vice versa):
Ensures redundancy; one pump works while the other stays on standby for automatic takeover if needed.
Dual Pump Alternation:
Designed to balance pump usage, alternating operation to reduce wear and extend lifespan.
Timed Rotation in Dual-Pump Alternating Mode
Ideal for continuous-duty systems (e.g., HVAC), where pumps rotate at fixed intervals to balance runtime and reduce wear, even without demand changes.
Cyclic Timing:
Suitable for systems with periodic demand, starting and stopping pumps at preset intervals.

Manual
Operator manually starts or stops the pump. Suitable for short-term operations, maintenance, or testing scenarios.
Auto
Pump operates based on sensor signals (liquid level, pressure, flow, etc.). Ideal for automated systems with dynamic requirements, like high-rise water supply or drainage.
Timer
Pump runs according to preset time schedules. Suitable for continuous processes without sensor feedback, such as HVAC or aeration systems.
Cyclic Timing Run Duration: Up to 999hrs 59min
Cyclic Timing Stop Duration: Up to 999hrs 59min
Remote management
Pump control and monitoring via remote platform. Suitable for distributed or unmanned systems, enabling real-time supervision and alerts.
| Application Type | Common Challenges | IP65 ABS outdoor water pump control starter Solution |
| Chemical Plant Backup System | Unstable operation under high corrosion, temperature, and load; slow backup pump response | This 3 phase dual pump intelligent control box supports duty/standby mode switching with independent runtime settings, enabling seamless backup pump activation for continuous operation in harsh conditions. |
| Hospital Dual Water Supply | Extremely high requirement for continuous supply, no interruptions or switching delays allowed | Utilizes no-break dual pump rotation control technology, intelligently managing pump operation to ensure uninterrupted water supply and system redundancy safety. |
