Product Description
Product Introduction
The ZU-I 8 Channel Intelligent Syringe Pump System is a multi-channel precision liquid handling system designed for laboratory research and automated liquid dispensing applications.
Featuring a 7-inch industrial-grade color touchscreen controller, the system can simultaneously display the working parameters and operating status of up to 8 independent pump units, providing an intuitive and efficient operation experience.
The split-type design allows flexible configuration of multiple pump units according to experimental requirements. Each pump unit can operate independently or work together under a logic control mode, making it suitable for complex liquid transfer processes requiring synchronized infusion and withdrawal.
With intelligent calibration, online micro-adjustment, real-time monitoring, bubble elimination function, and RS232/RS485 Modbus communication, the ZU-I provides accurate, stable, and flexible liquid dispensing solutions for laboratories and automation systems.

Key Features
1. 8 Channel Independent Control
The system supports 1–8 optional pump units.
Each pump unit can work independently with:
- Different flow rates
- Different operation times
- Independent infusion or withdrawal parameters
This allows multiple liquid handling processes to be performed simultaneously.
2. Independent Mode & Logic Mode
Two flexible working modes are available:
Independent Working Mode
Each pump unit operates independently.
Users can set:
- Different flow rates
- Different volumes
- Different operating times
for each channel.
Logic Working Mode
Multiple pump units operate according to preset time relationships.
Features:
- Synchronized operation
- Different infusion/withdrawal ratios
- Flexible multi-step liquid transfer processes
3. Intelligent Calibration System
The intelligent calibration function improves dispensing accuracy by compensating for volume deviation.
Additional functions:
- Online micro-adjustment
- Individual pump volume correction
- Reduced dispensing error
4. Real-Time Monitoring
The 7-inch touchscreen controller provides:
- Real-time operating status display
- Animated operation monitoring
- Flow alarm notification from each pump unit
Users can easily monitor the entire system during operation.
5. Bubble Elimination Function
The adjustable back distance setting helps:
- Remove bubbles inside the syringe
- Improve dispensing accuracy
- Maintain stable liquid delivery
6. Fast Forward & Reverse Function
The fast forward and backward functions simplify:
- Syringe loading
- Tube washing
- Flow protection unlocking
Improving daily operation efficiency.
7. Flexible Communication & Integration
Supports:
- RS232 communication
- RS485 communication
- Modbus RTU protocol
Suitable for integration with:
- Laboratory automation systems
- Analytical instruments
- OEM equipment
