DM/JM Series Digital Metering Pumps
DM/JM Series Digital Metering Pumps feature modular-designed hardware and software for precise digital control. These pumps are compatible with mechanical diaphragm, plunger, and hydraulic diaphragm metering pumps and can meet explosion-proof requirements. With simple mechanical structure and easy installation & maintenance, they integrate multiple intelligent functions for broad application coverage.
The JM Series features a large-size high-definition backlit LCD with keypad operation, while the DM Series offers touch-screen HMI for enhanced convenience. Building on JM Series functions, the DM Series supports pressure and liquid-level monitoring & alarm, plus high-precision metered dosing in timing and cyclic operation modes.
