The history of Milton Roy dates back to 1936, when Milton Roy Sheen and his son, Robert T. Sheen, formed a partnership to manufacture and sell controlled volume pumps. The first pumps were designed to satisfy a chemical feed requirement discovered by Robert, and they were assembled in the basement of Milton Roy’s home. It was there he created the initial patters for castings.
The pumps proved so successful for various chemical applications that the Sheens soon devoted all their time to this fast-growing enterprise. Since its humble beginnings, Milton Roy has evolved and grown immensely over the years. By 1964, the company had diversified into the biomedical field and was instrumental in the development of the first artificial kidney machine. Milton Roy worked closely with a team of physicians and scientists to deliver one of the first single-patient dialysis systems.
Other Milton medical breakthroughs include the manufacturing of early contact lenses and the first air-fluidized bed specifically designed for burn patients. Milton Roy continued to expand into new industries with an innovative approach and a steadfast commitment to quality. These values continue to drive the company today.

PRODUCT OVERVIEW
Milton Roy is the world’s largest manufacturer of controlled volume (metering) pumps that set the industry standard for performance, accuracy and durability. Milton Roy concentrates its scientific, engineering and production resources on the development and manufacture of equipment that accurately controls fluids ranging from water to high-viscosity polymers, corrosive or abrasive chemicals, toxic substances and other difficult-to-pump media.
In addition to a wide range of pumps, Milton Roy also provides pulsation dampeners, streaming current detectors, tanks and chemical feed systems.
METERING PUMPS
The metering pump is a positive displacement chemical dosing device with the ability to vary capacity manually or automatically as process conditions require. It features a high level of repetitive accuracy and is capable of pumping a wide range of chemicals including acids, bases, corrosive or viscous liquids and slurries.
The pumping action is developed by a reciprocating piston, which is either in direct contact with the process fluid or is shielded from the fluid by a diaphragm. Diaphragms are actuated by hydraulic fluid between the piston and the diaphragm.
Metering pumps are generally used in applications where one or more of the following conditions exist:
- Low flow rates in mL/hr or GPH are required
- High system pressure exists
- High accuracy feed rate is demanded
- Dosing is controlled by computer, microprocessor, DCS, PLC or flow proportioning
- Corrosive, hazardous or high-temperature fluids are handled
- Viscous fluids or slurries need to be pumped.
SOLAROY Solar-Powered Chemical Injection Pumps
SOLAROY pumps are designed with innovative features that provide ultimate solar-powered performance. Compact and economical, SOLAROY solar-powered pumps are driven by solar energy and built to work in the harshest environments and the most remote locations. Additionally, SOLAROY Solar-Powered pumps are designed to last. These “set it and forget it” pumps work continuously, reducing shutdowns and lost production.
mROY Series Metering Pumps
The mROY Series sets the metering pump standard for durability and performance in a compact and cost-effective design. First introduced in 1962, the mROY has proven itself to be a 24/7 metering pump with installation life expectancy of 20 years or more. Various models and frame sizes provide capacities from 0.21 GPH (0.8 l/hr) up to 170 GPH (644 l/hr). There are models that can generate up to 3,000 psi (207 bar) but still provide economical performance at low pressures.
The mROY is used in a wide variety of applications including water and wastewater treatment, boiler chemical feed, oil and gas additives, process chemical injection, pH control chemicals, and many others. A wide range of options assure that the mROY will meet all the application requirements within its range.
PRIMEROYAL Series Metering Pumps
Milton Roy’s PRIMEROYAL series pumps combine robust, field-proven technology, flexible design, and the capability to accurately dose a broad spectrum of chemicals, making these pumps suitable for a large number of industrial processes.
These pumps feature a variable eccentric drive with a no-lost-motion design. This drive enables precise control of the pump delivery rate while meeting or exceeding industry standards for steady-state accuracy and repeatability.
PRIMEROYAL pumps achieve reliable performance within a minimal footprint. With five frame sizes with wide flow rate and pressure ranges and a selection of liquid-end configurations and options, PRIMEROYAL pumps can be precisely configured for your applications.
Milton Roy’s new PRIMEROYAL X Series pump extends capabilities in even the most challenging environments at 20K PSIG. This latest addition to the PRIMEROYAL series of pumps pushes the boundaries for greater flow and higher pressures in a wide range of oil and gas applications. The PRIMEROYAL X helps to prevent hydrate formation, wax and scale deposits, and corrosion to manage production effectively.
