Chemical Feed Systems,
Dosing Pumps &
Water Treatment Equipment

LibertyCES supplies complete chemical feed systems including metering pumps, diaphragm dosing pumps, mag-drive sealless centrifugal pumps, chemical dosing skids, and PLC-controlled dosing panels for water treatment, wastewater, and industrial chemical applications. Every system is specified to the exact chemistry, flow rate, pressure, and compliance requirements of the application — not selected from a catalog.

LibertyCES supplies electromagnetic diaphragm metering pumps, motor-driven diaphragm pumps, peristaltic hose pumps, mag-drive sealless centrifugal pumps, and AODD/EODD transfer pumps from manufacturers including ProMinent, Blue-White Industries, Finish Thompson, and Graco. Pump selection is matched to chemical compatibility, flow accuracy requirements, and system back-pressure.

Chemical dosing pumps integrate with SCADA systems via 4–20mA analog signals, pulse frequency control, or Modbus/Profibus communications. LibertyCES specifies dosing systems with compatible signal outputs, differential pressure monitoring for pump health, and dry-run protection through level sensors and flow switches — enabling full remote visibility and alarm integration with existing plant SCADA infrastructure.

LibertyCES supplies XLPE crosslinked polyethylene tanks for oxidizers and sodium hypochlorite, HDLPE extrusion-wound tanks for aggressive acids and bases, double-wall SAFE-Tank systems for SPCC secondary containment compliance, cone-bottom tanks for solids-bearing chemicals, and FRP containment enclosures. Tank selection is matched to chemical family, concentration, temperature, and regulatory requirements.

The terms are often used interchangeably, but in precise engineering usage, a metering pump specifically refers to a pump with calibrated, repeatable flow accuracy — typically ±1% — used where precise chemical dose rates are critical. A dosing pump is the broader category. All metering pumps are dosing pumps, but not all dosing pumps meet the accuracy standard required for precision metering applications such as disinfection dosing or pH neutralization.

LibertyCES verifies material compatibility at the component level for every specification — wetted pump materials, valve seats and seals, tank liner materials, piping alloys, and gasket compounds are all checked against the specific chemical, concentration, temperature, and pressure of the application. James Riggins does not rely on generic compatibility charts for critical applications. Compatibility is verified before equipment is specified.

LibertyCES serves municipal water and wastewater treatment plants, industrial wastewater treatment, chemical processing facilities, mining and mineral processing operations, agriculture and fertigation systems, food and beverage manufacturing, and industrial facilities requiring EPA and SPCC compliance. LibertyCES is headquartered in California and serves industrial plants and utilities nationwide across the United States.

Yes. LibertyCES specifies and supplies SCADA-ready chemical dosing systems including 4–20mA transmitters, pH/ORP sensors, differential pressure monitors, flow meters, and PLC control panels. These systems provide real-time chemical feed visibility, automated dose-rate adjustment, and alarm outputs compatible with existing plant SCADA infrastructure.
