Since 1936, Milton Roy has set the global standard for controlled-volume fluid handling. Our metering pumps, industrial mixers, and engineered dosing systems operate in thousands of installations across six continents — delivering ±1% accuracy, chemical resistance, and decades of reliable service in industries where precision isn't optional.
As part of the Ingersoll Rand family of fluid handling brands - alongside Dosatron, LMI Pumps, ARO, Seepex, and YZ Systems - we offer an unmatched ecosystem of complementary technologies for every fluid challenge your operation may face.
Water & Wastewater Treatment
From potable water production to desalination and industrial effluent treatment, Milton Roy provides precision chemical dosing and mixing solutions for every stage of the water treatment lifecycle. Our metering pumps and agitators ensure accurate injection of coagulants, disinfectants, pH control agents, and membrane protection chemicals — helping operators meet regulatory standards while optimizing costs.
Energy
Milton Roy provides precision chemical injection, metering, and mixing solutions across the full energy spectrum. Our API 675-compliant pumps and engineered systems serve upstream oil & gas production, midstream pipeline operations, downstream refining, power generation, and petrochemical processing — delivering the accuracy, safety, and reliability that energy operators demand in the most challenging environments on earth.
Renewables & the Energy Transition
The world is accelerating its transition to sustainable energy — and Milton Roy is enabling it. Our metering pumps and industrial mixers support the production of renewable diesel, Sustainable Aviation Fuel (SAF), and Renewable Natural Gas (RNG) from waste feedstocks. From HEFA hydrotreatment reactors to final ASTM-compliant fuel blending, we deliver the precision and reliability these emerging processes demand.
Mining & Mineral Processing
The electrification revolution runs on lithium — and Direct Lithium Extraction (DLE) is the technology unlocking it sustainably. With recovery rates of 70–90% and production timelines measured in hours instead of months, DLE relies on the precise dosing of aggressive reagents (HCl, H₂SO₄, NaOH) at every stage. Milton Roy metering pumps are engineered for this exact environment: chemically resistant, high-accuracy, and built for continuous operation in remote, demanding conditions.
General Industry
Wherever a process demands precise, repeatable, and chemically resistant fluid control — Milton Roy delivers. From pharmaceutical cleanrooms to food processing lines, from pulp & paper mills to nuclear containment systems, our metering pumps and industrial mixers serve virtually every industry where controlled-volume accuracy matters. And with the Ingersoll Rand ecosystem behind us, we can pair our dosing technology with ARO's FDA-compliant transfer pumps, Dosatron's water-powered injectors, and Seepex's progressive cavity pumps.
