Hydraulic Diaphragm Metering Pump

The DM and JM digital metering pump series feature a fully modular hardware and software digital control architecture, supporting universal adaptation to mechanical diaphragm, plunger, and hydraulic diaphragm metering pumps.

For human-machine interaction, the JM series utilizes a large high-definition backlit LCD screen with physical key operation for stable, intuitive control. The DM series features a full-touch HMI for enhanced user experience, plus additional pressure and liquid level monitoring with fault alarm functions for high-accuracy fluid dosing with programmable timing, cyclic, and intermittent operating modes.
