Product Description
Hydraulic Diaphragm Metering Pump
Product Overview
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.
The complete series offers customized explosion-proof configurations for hazardous working conditions. With streamlined mechanical structure, these pumps enable effortless on-site installation and routine maintenance, while diverse intelligent functions expand application versatility across industrial scenarios.
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.
