Fsh-Fmi2020-B Fluid Injection Metering Dispensing Pump
**FSH-FMI2020-B Series High-Precision Fluid Dispensing / Refilling Pump**
The FSH-FMI2020-B series is a high-precision fluid dispensing and refilling pump system that combines a digital control box, a stepper motor, and one or two high-precision rotary ceramic pump modules driven by the motor. Its flexible design allows for easy integration into various systems, making it ideal for both automated and semi-automated production environments.
Key features include a 7-inch color touch screen interface with user-friendly English and Chinese options, standard communication interfaces such as PLC I/O, CC Trig, and AUX OUT, and a wide power supply range (100V–240V) without the need for voltage selection. The system’s high-precision ceramic pump modules are corrosion-resistant, maintenance-free, and designed for easy assembly and disassembly.
