LMI Milton Roy’s ROYTRONIC EXCEL Series AD pump is the new digital series of pumps within LMI’s solenoid-driven metering pump product lines. The series offers microprocessor control options and improved electro-magnetics to meet flow/pressure ratings and offers solutions for more versatile chemical injection with greater turn-down capability. The pumps are available for applications up to 250 PSI, with capacities between 0.002 and 2.0 GPH. Push-button controls for stroke speed and mode, LCD-user interface, stroke adjustment and a low-level float switch connection are available. Select models include a graphical display, alarm modes, external control options, pulse divide/multiply modes, pulse and 4-20 mA input and output connections, dual low-level switch connection, universal voltage and advanced electronic features for pump configuration. The line features an advanced design fitting system for secure, leak-proof tubing connections on standard liquid ends and includes half-inch NPT connections. The new design includes a plastic enclosure that prevents leakage, watertight electrical connectors with enhanced corrosion resistance, and a durable clear cover to protect control features.
