Product Description
Product Introduction
Constinfuse Constant Flow Syringe Pump is a high-precision continuous flow syringe pump designed for microliter-level liquid transferring, dispensing, and precise flow control applications.
With an advanced constant flow control system, Constinfuse provides stable and uninterrupted liquid delivery with a wide flow rate range from 0.06 μL/min to 70 mL/min. It is ideal for applications requiring accurate and continuous micro-liquid handling.
The system supports RS232 and RS485 communication interfaces with Modbus RTU protocol, allowing easy integration with automated equipment and OEM systems.
Equipped with a 4.3-inch industrial-grade true color LCD touchscreen, intelligent calibration function, closed-loop control, and overload protection, Constinfuse ensures reliable performance, convenient operation, and long-term stability.
