JMA digital metering pump- Eco Online

JMA series digital metering pump - the best choice for precise metering and dosing

The intelligent JMA series digital metering pump created by Ligao Pump Industry provides customers with intelligent solutions for precise chemical dosing. The digital metering pump has a simple mechanical structure, easy installation and maintenance, and a unique drive design that makes flow control simple and precise. The pump integrates multiple intelligent designs and controls flow, liquid level, pressure, time, and other aspects. It is automatically operated and fed back through an integrated microprocessor, and the user-friendly touch based human-machine interface system makes operation more convenient.
