LMI ROYTRONIC® Series A chemical metering pumps are positive displacement pumps with a NEMA 4X/IP-65 enclosure. Relevant model codes are NSF, UL/CUL or CE certified and offer control options and improved electromagnetics to meet all flow/pressure ratings. Designed for commercial applications, the pumps are available for applications up to 250 psi with capacities between .001 and 2.0 GPH. Dual manual control options with pulse input or 4-20 mA input are available. Standard FastPrime™ liquid ends are equipped with a valve that allows for opening the head to atmospheric pressure to assist in pump priming. Standard half-inch NPT connections allow for ease of configuration. Ferrule designed fittings offer secure, leak-proof tubing connections.

LMI ROYTRONIC EXCEL™ Series AD pumps achieve a new level of innovation in solenoid-driven metering pump technology. Offering a robust design, microprocessor control options and improved electromagnetics to meet all flow/pressure ratings, ROYTRONIC EXCEL™ Series AD chemical metering pumps will provide industry solutions for more versatile chemical injection with greater turn-down capability.
The line includes an advanced design fitting system for secure, leak-proof tubing connections. Every pump with a FastPrime™ or AutoPrime™ liquid end includes half-inch NPT connections to allow for ease of configuration.
Standard FastPrime™ liquid ends incorporate a unique design to bleed the head without depressurizing the discharge tubing. FastPrime™ liquid ends are available with a variety of material constructions to meet demanding application requirements. Optional AutoPrime™ liquid ends automatically and continuously purge entrapped air from process fluid, eliminating "vapor lock" with liquids such as sodium hypochlorite, even in remote installations. High Viscosity liquid ends engineered to pump your most challenging viscous fluids are also available.
