LMI, a US-based controlled-volume metering pump manufacturer and a brand of Accudyne Industries, has introduced the Excel XR line of intelligent metering pumps.
The Excel XR metering pumps are designed for the specific requirements of municipal and industrial water and waste treatment.
Available in two control configurations, manual and enhanced, they also fit into the process control requirements of a wide range of applications, including general industry, agricultural, chemical, oil & gas, power generation, pulp & paper, textiles, and other applications.
The Excel XR features a mechanically actuated diaphragm that is driven by advanced variable speed technology to handle low flows, with rates as low as .023l/h all the way up to 68l/h, with turndown capabilities of 1,000:1, with ±1% steady state accuracy.
The pumps can handle a wide range of chemicals, polymers, viscous fluids, and slurries without being affected by changes in discharge pressure.
They can communicate with digital or analogue devices to administer a variety of control schemes such as pulse input, timed events, or batch processes, and remote connectivity enables control and feedback in real time.
A newly designed backlit colour display allows for convenient navigation in five languages (English, French, Spanish, Portuguese, Chinese), and the pumps also feature a universal power supply (100-240V, 50/60 Hz) to provide high flexibility.
A wide range of options and accessories are available to customize the new pumps to varying applications, including backpressure valves, safety valves, pulsation dampeners, calibration columns, and degassing valves and systems.
Multiple liquid end materials, including polypropylene, PVDF, and 316L stainless steel are offered to fit the application requirements.
The Excel XR metering pumps are certified to NSF 61, required by a growing number of municipalities, thus assuring potable water plants that the new pumps are safe to use and are compatible with the chemicals being injected into the water treatment process.
