Jingjin Pump Applications and Solutions in Flow Chemistry

Meichen Luo, Technical Sales Engineer, Hangzhou Jingjin Technology Co., Ltd.

Continuous flow chemistry requires stable, reliable liquid delivery, but conventional pumps face challenges including pulsation, clogging with solids or viscous fluids, complex maintenance, seal failures with reactive chemicals, and metal contamination.
This presentation introduces Jingjin Pump, featuring four targeted solutions:

1.    JINGJIN Precise feeding system with triplex plunger – Designed for demanding applications, particularly solids-containing and high-viscosity liquids.

2.    JINGJIN Seconds-Switchable Integrated Flow Path Pump – Entire pump head replaces in <60 seconds, reducing downtime by >90%; fault recovery in under a minute.

3.    JINGJIN Lithium Reagent Pump – Specialized design prevents crystallization and leakage when handling air-sensitive lithium reagents.

4.    JINGJIN Metal-Free Pump – Achieves <1 ppb metal leaching (ICP-MS verified) with =0.2% accuracy for semiconductor and ultra-pure applications.

All Jingjin pumps feature proprietary in-house cam design achieving pulsation < ±0.02 mL/min, and 36-point pressure-flow calibration maintaining ±0.5% accuracy across 0–42 MPa. Flow rates range from 0.003 mL/min (lab) to 1000 L/h (production). Widely adopted across chemical, pharmaceutical, and semiconductor industries.
