DM DIGITAL METERING PUMP

DM DIGITAL METERING PUMP

SUMMARY

To address the trends of automation and intelligentization, Ligo Pumps, drawing on years of experience in positive displacement pump applications, has developed its own intelligent digital metering pump, providing customers with intelligent solutions for precise chemical dosing. This digital metering pump innovatively employs stepper motor vector drive and an advanced MCU... The microcontroller unit and software program are customized and optimized to achieve accurate metering and dosing over a wide range. The digital metering pump features a simple mechanical structure , convenient installation and maintenance, and integrates multiple intelligent designs. It offers manual/automatic and remote/local modes, and monitors and controls flow, level, pressure, time, and safety alarms.  The system is automated through an integrated microprocessor for computation and feedback, and supports Modbus RTU.   The communication protocol enables bidirectional communication, and it features a user-friendly human-machine interface system (HMI/LCD). Make the operation more convenient .
