Reliable Dual Pump Control for Water Supply, Drainage and Industrial Pumping Systems
The One Control Two Pumps Control Panel is designed to control two water pumps from one electrical control cabinet. It is commonly used in water supply systems, drainage systems, sewage pumping stations, irrigation projects, industrial water treatment and building water management.
Instead of installing two separate control boxes, this panel allows two pumps to work in one coordinated system. The control panel can start and stop the pumps automatically according to water level, pressure signal or external control signal. It also helps balance pump operation, reduce manual operation and improve the reliability of the whole pumping system.
For different project requirements, we offer two configuration options:
- Standard Components Version
- CHINT Components Version
Both versions share the same basic control logic. The main difference is the internal electrical component configuration.
What Is a One Control Two Pumps Control Panel?
A One Control Two Pumps Control Panel, also called a dual pump control panel or duplex pump control panel, is an electrical control system used to manage two pumps in one cabinet.
It can be used for:
- One working pump and one standby pump
- Two pumps working alternately
- Two pumps starting together when water demand increases
- Automatic water level or pressure control
- Manual and automatic pump operation
In many water systems, using two pumps is safer than using only one pump. When one pump needs maintenance or cannot meet the required flow, the second pump can help keep the system running.
Standard Version and CHINT Components Version
We provide two common versions for different customer needs.
Standard Components Version
The Standard Version uses reliable general electrical components. It is suitable for normal water pump applications where customers need stable performance and a more cost-effective solution.
This version is commonly used for:
- Small and medium water supply systems
- Building drainage systems
- Agricultural irrigation
- General industrial water transfer
- OEM pump equipment
CHINT Components Version
The CHINT Components Version is equipped with CHINT electrical components such as breakers, contactors, relays or other key control parts according to project requirements.
This version is suitable for customers who prefer branded electrical components and easier component replacement in local markets.
It is commonly selected for:
- Engineering projects
- Municipal water and drainage systems
- Industrial pumping stations
- Distributor projects
- Customers with specified electrical component brand requirements

Main Functions
1. One Panel Controls Two Pumps
The panel is designed to control two pumps in one system. It simplifies wiring, saves installation space and makes daily operation easier.
2. Automatic and Manual Operation
The panel supports automatic operation through float switches, pressure switches, level sensors or other signal devices. Manual operation is also available for testing, maintenance and emergency use.
3. Lead-Lag Pump Alternation
The two pumps can work alternately. Pump A runs first in one cycle, and Pump B runs first in the next cycle. This helps balance the working time of both pumps and reduces wear on a single pump.
4. Standby Pump Function
When one pump fails or cannot meet the required flow, the second pump can start as a backup. This improves system reliability, especially in drainage, sewage and water supply applications.
5. Overload and Short Circuit Protection
The control panel can be equipped with overload protection, short circuit protection and phase protection according to the pump motor and power supply requirements.
6. Water Level or Pressure Control
The panel can work with float switches, liquid level controllers, pressure switches or other sensors. It starts and stops the pumps automatically according to actual system conditions.
7. Clear Operation Status
Indicator lights, switches and meters can be added to show power status, pump running status, fault status, voltage or current. This makes operation and troubleshooting easier.
Typical Applications
The One Control Two Pumps Control Panel is suitable for many pumping systems, including:
- Building water supply systems
- Basement drainage systems
- Sewage lifting stations
- Wastewater treatment systems
- Agricultural irrigation systems
- Industrial water circulation
- Fire water auxiliary systems
- Rainwater collection and discharge
- Cooling water circulation
- Pump rooms and water treatment projects
Product Features
Stable Dual Pump Control
The panel provides stable control for two pumps and keeps the system running more safely than a single-pump setup.
Flexible Control Logic
The panel can be designed for alternate operation, main-standby operation, simultaneous operation or customized control logic.
Easy Installation
The internal wiring can be arranged clearly before delivery. Customers only need to connect the power supply, pump motor cables and sensor signals according to the wiring diagram.
Customizable Electrical Configuration
Voltage, motor power, control mode, enclosure size and component brand can be customized based on project requirements.
Suitable for Different Pump Types
The panel can be used with submersible pumps, sewage pumps, booster pumps, centrifugal pumps, drainage pumps and other water pump systems.
Cost-Effective for B2B Projects
Compared with using two independent pump control boxes, one integrated dual pump control panel offers better system coordination and a cleaner installation layout.
Optional Configurations
Available options include:
- Standard electrical components

How Does the Dual Pump Control Panel Work?
When the control panel receives a start signal from a float switch, pressure switch or level controller, it starts one pump automatically. In the next working cycle, the other pump can start first to balance the operating time.
If the water level rises quickly or the flow demand increases, the second pump can start to support the first pump. When the water level or pressure returns to the set range, the panel stops the pumps automatically.
This control logic helps reduce manual operation and improves the stability of the pumping system.
