Description |
Recommended Applications |
|
Single-Pump Operation |
When one pump is unavailable, the other pump independently handles the entire system load. |
Ensures normal water supply/drainage during maintenance or failure of one pump. |
|
Duty/Standby Mode |
One pump runs continuously while the other remains on standby; automatic switch on failure. |
The 3S smart water pump controller is designed for continuous water supply systems or critical production lines. |
|
Alternating Rotation |
Both pumps alternate operation to average usage time and avoid single-pump aging. |
Long-cycle systems, agricultural irrigation. |
|
Dual-Pump Simultaneous Start |
Both pumps start together to increase instantaneous supply/drain capacity. |
Peak supply periods, large-flow flushing. |
|
Timed Rotation Operation |
Switches the operating pump on a scheduled cycle to improve efficiency in unmanned scenarios. |
Night automatic operation systems, well replenishment systems, etc. |
Chip: ST Industrial MCU (Top 3 globally)
The ST MCU rapidly collects and processes multi-dimensional signals such as
voltage, current, liquid level, and pressure, ensuring faster and more precise
controller response.
Relay: HONGFA (Top 1 in China and Top 3
globally)
The HONGFA relay delivers highly reliable switching, ensuring precise and
stable pump motor start/stop, enhancing overall system reliability.
MCB: CHINT (Top 1 in China)
CHINT MCB quickly disconnects the circuit when current exceeds the rated value,
preventing motor overheating and equipment damage.
AC Contactor: CHINT (Top 1 in China)
CHINT AC contactor enables remote start and stop of the pump motor, ensuring
precise operation and enhanced control convenience.

Application Type |
On-site Challenges |
3S smart water pump controller Solutions |
|
Small-Scale Industrial Water |
Frequent start/stop cycles causing controller aging. |
Start/stop signal delay control plus multiple protections to extend equipment life. |
|
Landscape & Garden Pumps |
Seasonal operation demands make frequent parameter adjustments inconvenient. |
Alternating rotation plus timed modes for automatic operation, saving time and effort. |
Regularly clean the enclosure to prevent dust buildup from affecting heat dissipation.
Monitor pump run times and rotate duty/standby order as appropriate.
Inspect wiring terminals and relay contacts quarterly to ensure they are secure and free of corrosion.
If the equipment will be unused for an extended period, enable the automatic rotation/rust-prevention function to keep the pump shaft flexible.
Q1: How to avoid frequent start/stop due to
level fluctuations?
A1: Configure a 0–60 second start/stop delay to filter short-term level changes. The duplex
pump control panel also includes frequent-start protection logic.
Q2: What is included in the standard
package of the 3S intelligent pump controller?
A2: The standard package includes: duplex pump control panel, product manual,
certificate of conformity, and mounting screws—ready for quick
deployment out of the box.
