HF-N6-3L (DZ25)

The Closed-loop stepper motor drives a standard industrial peristaltic pump, using a 3.2″ true color LCD display. The flow rate and speed are displayed on the same screen. The knob speed adjustment + pure imported keys; speed range: 0.1-600 rpm, flow range: 0.211-3600 ml/min; it can be applied to a variety of pump heads and various external control methods. It supports RS232/RS485 communication and standard MODBUS communication protocol (RTU mode). It is suitable for industrial sites with large flow, wide range and high-precision liquid transmission.
