Features:

1. It is a kind of dual piston series pump with reciprocating constant pump, with high flow accuracy; 

2. By applying stepping motor control technology, it ensures the motor to run smoothly and accurately in low speed, which improves the accuracy and  repeatability of analysis under low flow rate and ensures the stability of flow phase composition under low flow rate and high pressure gradient system; 

3. The installation way of floating guide plunger rod, high-quality plunger rod, seals and other key components ensure its infusion pump stability and durability under long-running;

4. It functions with double correction of mobile phase compressibility and flow rate accuracy of the correction. According to solvent systems difference, it can conduct flow rate error compensation within ± 15%, which ensures high flow rate accuracy;

5. Through RS-485 for external control of chromatography workstation, users can easily get high-precision dual high-pressure gradient system, meanwhile achieve flow rate radiance to satisfy various demands of production and scientific research; 

6. Real-time pressure monitoring display, high and low pressure limit alarm functions to ensure the safety of the instrument under working; 

7. Large flow flushing solvent replacement to decrease solvent replacement time, thus improve work efficiency; 

8. OLED module display, friendly man-machine interface, easy and flexible to operate.
